13 Chapter 2 Unpacking and Installation This chapter outlines the unpacking and installation requirements. Read and follow the instructions carefully. Fryer must be installed and used in such a way to prevent water from contacting the shortening. Any shipping damage should be noted in the presence of the delivery agent and signed prior to his or her departure. NOTICE Installation of this unit should be performed only by a qualified service technician. This appliance is not intended to be operated by means of an external timer, extension cord or a separate remote control system. 2.1 Unpacking the Appliance Carefully remove the shipping crate and packing. Take care when moving the fryer to prevent personal injury. The fryer weighs approximately 665 lbs (302 kg). Do not puncture the fryer with any objects such as drills or screws, as electrical shock or component damage may result. To avoid personal injury, all counterweights must be installed and secured before attempting to unlatch the lid. 1) Cut and remove the plastic bands from the packing box. 2) Remove the packing box lid, and then lift the remaining packing box sides off the appliance. 3) Remove the 4 corner packing supports. 4) Cut the stretch film from around the carrier/rack box and remove it from the top of the lid. 5) Cut, remove and dispose of the metal bands holding the fryer to the pallet. Unpacking and Installation 3

14 2.1.1 Unloading the Appliance Carefully remove the appliance from the shipping pallet. The following steps requires a two person lift to prevent injury or damage to the appliance. 1. Set the casters in a forward position to prevent unexpected movement. 2. While one installer steadies the appliance, to prevent it from falling off the pallet, pry both side rails off the pallet. 3. Remove the counterweights from beneath the appliance. 4. Either prop a ramp against the pallet for each set of casters, and then roll the appliance off the pallet or lift the appliance off the pallet and set it on the floor Installing Counterweights Counterweights are used to offset the heavy lid, which is used to seal the vat during cooking. Carefully install the counterweights in to the rear of the appliance. Do not drop counterweights or personal injury may result. Each counterweight weighs approximately 20 lbs. (9 kg.) each. Unpacking and Installation To avoid personal injury, all counterweights must be installed and secured before attempting to unlatch the lid. 1. Remove the top and rear panel covers to access the counterbalance weight carriage assembly. 2. Insert the first through fourth counterweight segments into the counterbalance weight carriage assembly. 3. Remove the two bolts marked A to release the counterbalance weight carriage assembly. 4. Install the rear panel cover, and then the top panel cover. 4

15 2.1.3 Finish Unpacking the Appliance 1. Cut warning tags from lid assembly. 2. Open the carrier by unlatching the lock. 3. Remove the accessories from inside the filter drain pan. 4. Remove the protective paper from the fryer cabinet. 5. Clean exterior surfaces with a damp cloth. 2.2 Selecting The Location The proper location of the appliance is very important for operation, speed, and convenience. Choose a location which provides easy loading and unloading without interfering with the final assembly of food orders. Operators find that frying from raw to finish, and holding the product in a warmer provides fast continuous service. Landing or dumping tables should be provided next to the fryer. The best efficiency is obtained by a straight line operation, i.e. raw in one side and finish out the other side. Order assembly can be moved away with only a slight loss of efficiency. To properly service the fryer, 24 inches (60.96 cm) of clearance is needed on all sides of the fryer including access for servicing by removing a side panel. To prevent severe burns from splashing hot oil, position and install fryer to prevent tipping or movement. Restraining ties may be used for stabilization. To avoid fire and ruined supplies, the area under the fryer should not be used to store supplies. 2.3 Leveling The Fryer For proper operation, level the fryer from side to side and front to back. Use a leveling tool on the flat areas around the vat collar and a crescent wrench to adjust the castors. Failure to follow these leveling instructions can result in oil overflowing the vat which may cause serious burns, personal injury, fire and/or property damage. 2.4 Ventilation of the Fryer The fryer should be located with provision for venting into adequate exhaust hood or ventilation system to permit efficient removal of steam exhaust and frying odors. The exhaust canopy must be designed to avoid interference with the operation of the fryer. Consult a local ventilation or heating company to help in designing an adequate system. NOTICE: Ventilation must conform to local, state, and national codes. Consult your local fire department or building authorities. Unpacking and Installation 5

16 2.5 Electrical Requirements This fryer must be adequately and safely grounded (earthed) or electrical shock may result. Refer to local electrical codes for correct grounding (earthing) procedures or in absence of local codes, with The National Electrical Code, ANSI/NFPA No. 70- (the current edition). In Canada, all electrical connections are to be made in accordance with CSA C22.1, Canadian Electrical Code Part 1, and/or local codes. To avoid electrical shock, this appliance must be equipped with an external circuit breaker which will disconnect all ungrounded (unearthed) conductors. The main power switch on this appliance does not disconnect all line conductors. The electric fryer requires 208, 240 or 480 volt, three phase, 50/60 Hertz service. The power cord may be already attached to the fryer, or provided at installation. Check the data plate to determine the correct power supply. A separate disconnect switch meeting over-voltage category III conditions with proper capacity fuses or breakers must be installed at a convenient location between the fryer and the power source. It should be an insulated copper conductor rated for 600 volts and 90 C. For runs longer than 50 feet (15.24 m), use the next larger wire size. Unpacking and Installation 6

17 2.6 International Electrical Requirements Units being used outside the United States may not be shipped with the power cord attached to the unit because of the different wiring codes. The fryers are available from the factory wired for 200, 240, 380 and 415 volts, 3 phase, 50 Hertz service. A terminal block is mounted inside the fryer for the cable wiring. For equipment with CE mark only; to prevent electric shock hazard this appliance must be bonded to other appliances or touchable metal surfaces in close proximity to this appliance with an equipotential bonding conductor. This appliance is equipped with an equipotential lug for this purpose. The equipotential lug is marked with the following symbol. CE units require a minimum wire size of 4 mm to be wired to the terminal block. If a flexible power cord is used, it must be HO7RN type. NOTICE: The supply power cords shall be oil-resistant, sheathed flexible cable, no lighter than ordinary polychloroprene or other equivalent synthetic elastomer-sheathed cord. It is recommended that a 30 ma rated protective device such as a residual current circuit breaker (RCCB), or ground fault circuit interrupter (GFCI), be used on the fryer circuit.

31 Chapter 5 Oil Maintenance This unit was designed to operate with a reduced amount of oil as compared to previous models. Additionally it is designed with software driven controls that optimize oil life. Typically operators can expect 30 days of useful life from one vat of oil before replacement is required. These results vary based on the amount and frequency of product cooked and the operators adherence to a consistent maintenance schedule, which includes operator specific settings, filtering and polishing frequency, and cooking habits. NOTICE: To lengthen oil life and to keep product quality high do not skip oil filtration. The proper level of cooking oil is automatically maintained as long as the fresh oil tank is filled. See 3.4 Fill the Fresh Oil Tank, page 13 for procedures for filling the fresh oil tank. 5.1 W.A.S.S.H. W.A.S.S.H. is an acronym that Henny Penny uses to describe the environmental elements that breaks down oil prematurely, shortening the useful life of the oil, which drives up the cost of ownership. They are as follows: Water - Moisture naturally occurring in product along with other sources of water degrades oil. Reducing water contamination by filtering often and cleaning off excessive ice crystals before dropping product can extend the life of the oil. Air - Oil slowly oxidizes when it is in contact with air. Properly maintaining the fryer mechanically and hygienically, and following recommended cooking procedures can reduce oil usage. Close the lid when the unit is not in use. Salt - Salt within product and breading makes its way in to the oil during the cooking process. Reducing additional salt contamination by following best practices when breading, cooking, and seasoning product increases oil life. Never season or shake excess breading off over a vat of oil. Soap - Soap residue, even in undetectable amounts, left behind after the washing process degrades oil. Ensure vats are rinsed thoroughly after washing to protect oil life. Heat - The controls are designed to make frying product the most efficient process as possible. Following best practices when using the Henny Penny fryer ensures the longest oil life possible. One best practice is selecting a product menu and placing the fryer in Cool Mode when not in use. Oil Maintenance 21

32 5.2 Boil-Over Prevention The following rules are provided to prevent personal injury to the operator and damage to the appliance. Failure to follow these instructions can result in oil overflowing the vat which may cause serious burns, personal injury, fire and/or property damage. The oil may be stirred only during the morning start up procedure. Do not stir the oil at any other time. Brush all cracklings from vat surfaces during the vat clean out process. Make sure the unit is sitting on a stable surface and has been leveled during installation before use. Be certain the oil is never above the vat upper fill line. Be certain that the gas control valve and burners are properly adjusted (gas units only). Do not overload the racks with product (24 lbs. (10.9 kg) maximum), or place product with extreme moisture content into racks. Always use a high quality frying oil. Some low grade oils have a high moisture content and cause foaming and boiling over. When it is necessary to drop frozen product, dip the basket of product in the oil for just a moment and then remove. Wait a moment and then place the basket of product back in to the vat, and then start the timer. 5.3 Filtering Filtering prolongs the life of the oil, the unit as well as improves product quality. There are various ways to filter the oil. As an example, a quick filter automatically runs between cook cycles to clean the oil and remove debris from the vat. A daily filter is run at the end of the day to thoroughly clean the unit. A polish is a prolonged filtration cycle used to extend the useful life of the oil. This section explains how to access and navigate the filtration menus. Oil Maintenance With prolonged use, the flashpoint of the oil the point at which oil bursts in to a flame is reduced. Discard oil immediately if it shows signs of excessive smoking or foaming. Serious burns, personal injury, fire, and/or property damage may result. INFO: Drain the oil at 250 F (121 C) or less. Higher temperatures cause cracklings to burn on the steel vat surfaces after the oil has drained. 22

33 5.3.1 Filter Menus 1) Press and hold the Menu button until *MAIN* displays. Refer to 4.5 Main Menu, page 18. 2) Select 1. FILTER from the menu. Menu options display. 3) Push the Menu button repeatedly to access additional menus. Menu (screen) 1 Menu (screen) 2 Menu (screen) 3 Menu (screen) Quick Filter The 1. QUICK option allows operators to perform a quick filter of the oil on-demand. A quick filter runs automatically after every cook cycle. During the filtering cycle the oil does not fully drain. It maintains a constant level during filtering. Arrows pointing up and down with a sequence of tracing light displays. 1. Select 1. QUICK FILTER. A confirm prompt displays. If the operator selects: NO x, the display returns to the previous menu. YES, the drain opens automatically and the oil begins filtering. After a few moments, the drain closes and the oil returns to the vat. When the vat is close to full, the control panel chirps and a display timer starts counting down. If the unit does not detect the oil returning to the vat and displays IS POT FILLED?, check the oil level to confirm the vat is full. If the oil is: Level with the hot fill line on the back of the vat, press YES. Not level with the hot fill line on the back of the vat, press NO x. The filter pump motor runs for an additional 30 seconds and pumps oil from the drain pan. Oil Maintenance 23

34 5.3.3 Daily Filter The 2. DAILY option allows operators to perform a daily filter of the oil and a wash cycle if desired. This filter cycle drains the oil from the vat completely enabling the user to clean the crumbs out of the vat and wash then down the drain. The crumb catcher in the drain pan holds the debris and the filter cleans the oil. 1. Select 2. DAILY. A confirm prompt displays. If the operator selects: NO x, the display returns to the previous menu. YES, the drain opens automatically and the oil begins draining. As the oil drains a brush symbol displays. Then three prompts display: FILL, WASH, DRAIN. The control attempts to detect when the pot does not empty properly. The control monitors the main temperature probe, and looks for it to begin cooling at a predetermined rate, as evidence that the oil has drained down below the probe and the probe is now air cooling. If by the end of the initial -Draining- step, the control has not detected sufficient temperature cooling on the main temperature probe, the control activates a display that graphically represents a blocked drain, and displays the messages DRAIN BLOCKED?, CLEAR THE DRAIN. The display continues until the expected cooling rate is observed on the main probe, or until the operator presses a button to acknowledge the message. Do the following: 2. Select the WASH option and the wash cycle begins, WASHING displays. Once completed, the display returns to the previous menu. Press STOP at any time to discontinue wash. Oil Maintenance 3. Press FILL to return the filtered oil to the vat. After a few moments, the drain closes and the oil returns to the vat. When the vat is close to full, the control panel chirps and a display timer starts counting down. Press STOP at any time to discontinue fill. If the unit does not detect the oil returning to the vat or if the vat sensor detects the oil is below the full line the message IS POT FILLED? displays. Check the oil level to confirm the vat is full. If the oil is: Level with the hot fill line on the back of the vat, press YES. Not level with the hot fill line on the back of the vat, press NO x and the filter pump motor runs for an additional 30 seconds. 24

35 5.3.4 Polish The 3. POLISH option extends the usable life of the oil by removing debris through an extended polishing (filtration) process. An automatic polish to help increase the life of the oil automatically occurs during the morning startup, after every cook cycle, and during the daily filter.

Empty the condensation drain pan and rinse it out with clean water. Maintenance 27

38 Clean the drain pan and replace the filter Daily Filter A daily filtering of the oil is essential to prolong the life of the oil and the unit. This unit uses less oil than traditional fryers so attention must be paid to the build-up of crumbs and cooking debris in the bottom of the vat(s). A quick filter runs after every cook cycle to keep the oil clean and debris to a minimum; however, a daily filter allows for a more thorough cleaning of the oil, vat, drain pan and a filter change. 1) Perform a daily filter cycle. Refer to Daily Filter, page Wipe Down the Unit Wiping down the outside of the unit is a sanitary practice that presents a professional appearance and improves product quality. While the unit is in Daily Filter mode do the following: 1) After covering the vat(s) with a sheet pan, use warm, soapy water and a cleaning sponge to wipe down the external components of the unit. Keep the sponge dry as possible to prevent the warm, soapy water from splashing in to the vat, contaminating the oil. 2) Clean around the vat band being careful not to drip water or drop debris in to the vat. 3) Wipe off the nylatron filler strips. Once a month a more thorough cleaning is required. Refer to 6.5 Cleaning Nylatron Filler Slides - Monthly, page 29. 4) Once the daily filter cycle is complete, clean the control board after enabling Wipe Mode. Refer to 6.2 Wipe Mode, page Clean the Fresh Oil Tank (ATO) The fresh oil tank (box) is a storage tank of fresh oil for the Automatic Top Off (ATO) system. Daily pull the tank out half-way, lift the lid, and then top off with fresh oil. As necessary, pull the tank out, clean, and then refill with fresh oil. While the daily filtering process is cycling do the following: Maintenance NOTICE: Inspect the fresh oil tank o-rings and replace if damaged or every 90 days. 1) Pull out the fresh oil tank halfway and open the lid. Refer to 3.4 Fill the Fresh Oil Tank, page 13 and Chapter 4 Operation, page 15. 2) Pull the tank out half way and then lift up, continue pulling out the tank. 3) Empty the oil in to a bulk oil disposal container. 4) Clean the tank with warm soapy water, and then rinse thoroughly. 5) Dry thoroughly, and then install the tank back in to the unit. 6) Add fresh oil to the tank as required. 7) Close the lid and carefully push the fresh oil tank back in to place. 28

39 6.3.4 Clean the Drain Pan The drain pan is a self-contained assembly underneath the unit that filters and polishes the oil to prolong oil life. In addition it catches and holds debris such as breading that falls off product during the cooking cycle. Once the daily filter process completes do the following: NOTICE: Inspect the drain pan o-rings and replace if damaged or every 90 days. 1) Carefully pull the drain pan assembly out from under the unit. 2) Remove the lid, clean, dry, and then set aside. 3) Remove the crumb catcher, clean, dry, and then set aside. 4) Remove the filter assembly. 5) Remove the filter envelope and discard. 6) Clean, dry, and then set aside the filter assembly components. 7) Clean, dry, and then set aside the drain pan. 8) Refer to 3.2 Drain Pan Assembly, page 10, install a new filter envelope, and then reassemble the drain pan. 9) Insert the drain pan under the unit until it latches. 6.4 Clean the Castor Wheels - Weekly Spray Henny Penny biodegradable, food safe, foaming degreaser (part no.12226) on castor wheels at least once a week as part of the normal cleaning routine. This prevents the long term build up of grease and dirt which can inhibit the normal operation of the wheels. Wheels laden with grease and dirt may stick or stop rolling which can make the fryer wobbly and unstable when moving. An unstable fryer can spill oil or tip over, causing damage to the fryer or serious personal injury. 6.5 Cleaning Nylatron Filler Slides - Monthly The Nylatron Filler Strips prevent food debris from entering the inside of the unit. Keeping them clean prolongs the life of the strips. Missing, broken or worn strips must be replaced. Or the internal mechanics of the unit becomes clogged with oil and food debris. 1. Spray Henny Penny biodegradable, food safe, foaming degreaser (part no.12226) on Nylatron filler strips. 2. Raise the lid up and down several times to spread the degreaser. 3. Wipe the Nylatron filler strips to remove food soil, grease, and degreaser residue. Maintenance 29

40 6.6 Oil Disposal Oil disposal is unique to each fryer. Three unique oil disposal types are available; manual, rear or front disposal. The manual method of bulk oil disposal, which requires a mobile cart Oil Disposal Shuttle (ODS), replaces the filter drain pan during the disposal process. The oil is drained directly from the vat in to the cart. Once the cart is full it is removed and taken to a bulk oil container where it is emptied. This process is repeated until the vat is drained of old unusable oil. The rear disposal process requires an on site external bulk oil disposal container which is permanently connected to the rear of the fryer by tubing. The oil is pumped from the rear of the fryer to a remote bulk oil container. The front disposal method requires a portable tank or external bulk oil disposal container that uses a hose to connect to a spigot on the front of the fryer, just to the left of the drain pan. The disposal type must be initially selected in the Special Programming menu by the installer at setup. If the disposal method changes over time the setting can be modified as required. Refer to 8.5 Special Programming, page 73, SP-17 menu for detailed instruction Dispose Menu Overview Select the 1. FILTER menu, and then press the Main menu button twice to select 7.

41 6.6.2 Manual Oil Disposal This section explains the manual process for draining and disposing of oil. Once the oil has degraded, the vat is drained completely and refilled with new oil. The degraded oil is manually transported to an oil storage container, using an Oil Disposal Shuttle (ODS). Use PPE. Oil can be dangerously hot. Allow the oil to cool to 100 degrees before removing. Hot oil should not be manually transported in a non-approved container, even for short distances. Always use an Oil Disposal Shuttle (ODS) or approved container, such as a metal pan with insulated handles and a locking lid. Ensure the drain pan is empty prior to preforming these procedures. The ODS and all metal pans transfer heat, which can cause serious burns. Pumping hot oil through the ODS damages the pump over time. NOTICE: To protect community sewer lines, oil must be trapped and disposed of through bulk removal. Hot oil can coagulate when cooled, which clogs pipes and sewer lines. Always dispose of oil in to an approved bulk oil disposal storage container or approved grease trap. Never pour oil down a public sanitation drain. Henny Penny recommends using an automated bulk oil disposal system, or a manually operated Oil Disposal Shuttle (ODS) to drain degraded oil from the vat and transport it to an approved oil disposal storage container Access the Dispose Menu Use the following steps to access the disposal menu.

49 6.7 Clean-Out Mode After the initial installation of the fryer and during every oil change, the vat must be thoroughly cleaned. There are two ways to clean the vat using the clean-out mode, heated and cold soak. Operators can fill the vat with warm water and cleaning solution, enable heat, and then scrub the vat immediately (P.M.) or let it soak overnight cold and scrub it in the morning (A.M.). Cleaning the vat immediately is called a Heated Clean-Out and allowing the vat to soak overnight is called a Cold-Soak Clean-Out. The choice of which type of clean-out an operator uses is set during installation within the software settings. Refer to Drain and dispose of the oil before performing these procedures. Refer to 6.6 Oil Disposal, page 30 for instructions. Do not close lid with water and/or cleaner in vat. Water under pressure becomes superheated. When lid is opened, escaping water and steam can result in severe burns. Always wear chemical splash goggles or face shield and protective rubber gloves when cleaning the vat as the cleaning solution is highly alkaline. Avoid splashing or other contact of the solution with your eyes or skin. Severe burns and possible blindness can result. Carefully read the instructions on the cleaner. If solution comes in contact with your eyes, rinse thoroughly with cool water and see a physician immediately. Do not use steel wool, or other abrasive cleaners or cleaners/ sanitizer containing chlorine, bromine, iodine or ammonia chemicals, as these deteriorate the stainless steel material and shorten the life of the unit. NOTICE: Do not use a water jet (pressure sprayer) to clean the unit, or component damage may result. Do not bang brushes or scrapers on the pot band. Damage to the pot band may cause gaps around the gasket disallowing pressure to build when sealed. Make sure the inside of the vat, the drain valve opening, and all parts that come in contact with the new oil are as dry as possible Setting the Clean-Out Mode Type Operators can choose between a Heated and a Cold-Soak clean-out.

53 Chapter 7 Annual Inspections Operators should perform the following inspections every 90 days. A certified technician should inspect the entire fryer once a year. 7.1 Inspect Castors and Frame Ensure the fryer s castors are clean and operational by doing the following. A cracked frame creates a tipping risk. If cracked frame is found, immediate attention is needed to repair the frame by having it professionally repaired by a welder, or having the fryer replaced. Ensure the fryer sits level, casters are mechanically sound and able to hold the weight of the fryer, and that the tube steel frame is not cracked or bent. If the fryer is not level, inspect the condition of the floor. Repair the floor as necessary, have any missing or cracked tiles replaced. If there is a slope due to a floor drain, the fryer may need to be repositioned so the caster is on level flooring. Casters on the fryer cannot be adjusted up or down. Inspect casters and the tube steel frame by removing the side panels and using a flashlight to look for cracks and/or bent framing. Replaced any damaged or broken casters by doing the following: 1. Raise the lid to lower the fryer s center of gravity. 2. Discard oil from the fry pot. 3. Remove the racks from the carrier. 4. Position two floor jacks under the frame (A), near the casters (B), on the same side of the fryer. 5. Block the casters on the opposite side of the fryer with small wheel chocks. 6. Raise the fryer approximately 2.5 (63mm). 7. Use an adjustable wrench to remove the caster (B). 8. Use an adjustable wrench to install the new caster. Ensure a snug fit but do not overtighten. 9. Continue to the next inspection or reinstall components as applicable. Annual Inspections 43

54 7.2 Inspect Counterweight Cables This unit uses two cables in the counter-weight mechanism that helps in the raising and lowering of the lid. Cables should be visually inspected yearly, either as part of a planned maintenance program or during a routine service call. Cables more than 10 years old should be replaced regardless of inspection results. Call for service to have both cables replaced. : If the lid becomes difficult to operate, stop using the fryer and call for service because the cables need to be replaced. Worn Counterweight Cable Usable Counterweight Cable 1. Use a 3/8 socket, to remove the 6 keps nuts around exterior of rear cover and remove the back shroud. 2. Inspect the counter-weight cables. If cables have cracks in the jacket, missing pieces in the jacket, or other obvious signs of wear, replace both cables. Annual Inspections 3. Continue to the next inspection or reinstall components as applicable. 44

55 7.3 Inspect and Lubricate the Carriage Wheels The carriage wheels inside the back of the fryer should be lubricated at least once a year to allow for easy lid movement. 1. If necessary, use a 3/8 socket to remove the 6 keps nuts around exterior of rear cover and remove the back shroud. 2. Inspect the carriage wheels and ensure proper operation. 3. Use spindle lube (PN 12124) and place a small amount on all four (4) wheels, both top and bottom, left and right rollers. 4. Continue to the next inspection or reinstall components as applicable. 7.4 Oil Migration Inspect behind the left side panel for excessive oil seeping through either the high limit pot fittings, the temperature probe pot fitting, level probe fitting, pressure transducer fitting, or the heating element fittings.

SP-22 CLEAN-OUT TYPE The Clean-Out function supports two different water based clean-out modes, Heated and Cold-Soak. Heated is heated and timed while Cold-Soak is unheated and not timed. KFC software is hard-coded for Cold-Soak only, it cannot be changed. SP-23 CLEAN-OUT TEMP If Heated mode is selected in the SP-22 menu, operators may select a temperature between 40 F 195 F with which to heat the water. Higher temperatures require Personal Protective Equipment (PPE) to prevent burns. If Cold-Soak mode is selected in the SP-22 menu, this setting displays Cold-Soak and can not be changed. SP-24 CLEAN-OUT MINUTES If Heated mode is selected in the SP-22 menu, operators may select a time 1 Min. to 99 Min. The timer starts after the water is heated to the temperature selected in SP-23. The clean cycle time allows the amount of time necessary to scrub the vat and lid before prompting to drain and rinse. If Cold-Soak mode is selected in the SP-22 menu, this setting displays Cold-Soak and can not be changed. Programming 75

86 8.6 Filter Control The Filter Control mode allows the parameters during a filter cycle to be modified for the best results depending on the oil type. Each parameter is grouped into a section that controls a particular settings. See Table 8-3 Filter Settings, page 76. To access the Filter Control menu do the following: 1) Press and hold the menu button until *MAIN* displays. 2) Press the menu button again. The 4. PROG menu displays. 3) Select 4. PROG. 4) Type 123. The 6. FLTR CTRL menu displays. 5) Select 6. FLTR CTRL. 6) Use the left or right arrow to navigate through the options. Table 8-3 Filter Settings Program Code Display Description Quick Filter Settings INFO: The Start-up Mix and the Cook Mode Auto Mix operations are specialized versions of the Quick Filter, and share some of the Quick Filter programmable parameters. For example, both of the Mix operations use the Quick Filter s Max Pump Time setting. For very thin (low viscosity) cooking oils, drain opening setting may need to reduce from the default value and you might need to reduce the drain opening setting from the default value. For 50 Hz systems, or if the control routinely gives up before the pot is refilled, you might need to increase the max pump time from the default value 50 Hz pumps may run more slowly than 60 Hz pumps. These parameters control the Quick Filter operation. The Quick Filter has three basic steps: 1. DROP - Opens the drain and drops the oil level by a certain amount. Depending on settings, may drop the oil level just a few inches during this phase, or could drain the entire pot. Programming 2. FILTER - Runs the filter pump with the drain partially open for a given time, pumping the oil through the filter paper to clean the oil. This operation typically holds a relatively constant oil level in the pot. 3. FILL - Closes the drain fully and runs the filter pump to refill the pot. Watches for a temperature rise on the upper temperature probe (level probe) to indicate that the pot has refilled. Runs the pump a bit longer to get the last of the oil out of the drain pan, then turns the pump off. FC-1 FILTER TRACKING MODE There are two options, GLOBAL and MIXED MODE. GLOBAL - If selected, continue at FC-1A. 76

121 11.6 Nylatron Filler-Strip Replacement Nylatron filler strips are used to cover the open slots the lid's lifting arms use to travel up and down through during normal operation. The strips prevent grease laded vapors and breading from entering the counterbalance weight carriage assembly area in the rear of the unit. The strips do not bear any of the lid's counterbalance weight. One end of the strip is connected to the internal end of the lid's arm, and the other to the counterbalance weight carriage assembly in the back of the unit. The strip moves through a channel in the front shroud as the arm and counterbalance weight carriage assembly moves up and down with the lid. The counterbalance weight carriage assembly is connected to the lid's arms with cables that bear and counterbalance the lid's weight. Without proper cleaning the channels fill with debris and add friction to the movement of the Nylatron filler strips. Eventually the strips fail and must be replaced. Objects can fall and splash hot oil or hot water while performing this procedure. Cover the vat with a sheet pan or drain the vat and allow to cool otherwise serious burns may result. Lid may be hot. Allow lid to cool before performing this procedure, or burns may result. The lid and counterbalance weight carriage assembly moves with force and can cause injury Inspect the Nylatron Filler Strip Kit Part Number: SLIDE-SHROUD VERTICAL Before disassembling the fryer unit, open and inspect the Nylatron filler strip replacement kit.
