Manitowoc does not recommend the use of GFCI/GFI circuit protection to energize our equipment. If code requires the use of a GFCI/GFI then you must follow the local code. The circuit must be dedicated, sized properly and there must be a panel GFCI/GFI breaker. We do not recommend the use of GFCI/GFI outlets to energize our equipment as they are known for more intermittent nuisance trips than panel breakers. Part Number: 9291482 05/16 9

For installation of remote MF series units, consult a refrigeration service company to connect refrigeration lines to the remote condensing unit. Drain Connections If a mechanically cooled refrigerated base does not have a condensate evaporator supplied, you must connect the condensate line to a suitable drain. Otherwise, water will collect on the floor, causing a potentially hazardous situation. Caster Installation Legs or casters must be installed and the legs or casters must be screwed in completely to prevent bending. When casters are installed the mass of this unit will allow it to move uncontrolled on an inclined surface. These units must be tethered/secured to comply with all applicable codes. The unit must be installed in a stable condition with the front wheels locked. Locking the front casters after installation is the owner s and operator s responsibility. Use a jack to lift the refrigeration unit off the ground just far enough to remove the caster. Place blocking underneath the unit. Do not work underneath a raised unit without proper blocking. Do not lift the unit more than necessary to remove the caster. Lifting the unit too far can make the unit unstable. 1. Carefully place the unit on its back. 2. Located at each caster mounting location are 4 bolts, for a total of 16. Remove them. 3. Place a locking plate caster over one of the front holes, matching the 4 mounting holes to the pre-drilled holes in the underside of the unit. Insert 4 bolts and tighten. 4. Repeat step 3 with the other three casters. 5. Carefully lift the unit upright.,caution After installing casters, the unit must stand upright for twenty-four (24) hours before being powered up to assure oil return to the compressor sump. Moisture collecting from improper drainage can create a slippery surface on the floor and a hazard to employees. It is the owner s responsibility to provide a container or outlet for drainage. All refrigerators have drains located in the bottom of the tank. An appropriate drainage area or container must be provided by the owner. 10 Part Number: 9291482 05/16

Section 4 Maintenance It is the responsibility of the equipment owner to perform a Personal Protective Equipment Hazard Assessment to ensure adequate protection during maintenance procedures. Failure to disconnect the power at the main power supply disconnect could result in serious injury or death. The power switch DOES NOT disconnect all incoming power. Disconnect electric power at the main power disconnect for all equipment being serviced. Observe correct polarity of incoming line voltage. Incorrect polarity can lead to erratic operation. Cleaning and Sanitizing Procedures,Caution Maintenance and servicing work other than cleaning as described in this manual must be done by an authorized service personnel. GENERAL When using cleaning fluids or chemicals, rubber gloves and eye protection (and/or face shield) must be worn. You are responsible for maintaining the equipment in accordance with the instructions in this manual. Maintenance procedures are not covered by the warranty. Never use sharp objects or tools to remove ice or frost. Do not use mechanical devices or other means to accelerate the defrosting process.

Maintenance Section 4 INTERIOR CLEANING Not When cleaning interior and exterior of unit, care should be taken to avoid the front power switch and the rear power cord. Keep water and/or cleaning solutions away from these parts. Not Never use a high-pressure water jet for cleaning or hose down or flood interior or exterior of units with water. Do not use power cleaning equipment, steel wool, scrapers or wire brushes on stainless steel or painted surfaces. The interior can be cleaned using soap and warm water. If this isn t sufficient, try ammonia and water or a nonabrasive liquid cleaner. To help prevent corrosion of the evaporator coil, store all acidic items, milk is slightly acidic, in seal-able containers. Immediately wipe up all spills. Cleaning the NLFAC milk dispensers This instruction applies to the model NLFAC dispenser only. A drain is supplied to simplify cleaning of the interior. Open the drain tube clamp. Drain accumulated liquid from the cabinet. Be sure to re-clamp the tubing before resuming operation of the NLFAC unit. After cleaning the interior and exterior as described, be sure to return the milk case loading tray to the bottom of the unit. The load tray is required not only for easy self-locating of milk cases, but it also ensures proper air flow through the evaporator coil for the air curtain. Not Any restriction to the air flow path, including leaving the milk case load tray out of the cabinet, will result in the voiding of your warranties. Self-Contained Units Evaporator Maintenance Each unit has a drain located inside the unit that removes the condensation from the evaporator coil and routes it to an external condensate evaporator pan. Each drain can become loose or disconnected during normal use. If you notice water accumulation on the inside of the unit, be sure the drain tube is connected to the evaporator drain pan. If water is collecting underneath the unit, make sure the end of the drain tube is in the condensate evaporator. The leveling of the unit is important as the units are designed to drain properly when level. Be sure all drain lines are free of obstructions. Remote Units Evaporator Maintenance The stainless steel condensate evaporator pan should be cleaned monthly. Use a vacuum cleaner or damp cloth to remove dust that may have accumulated. This will prevent corrosion of the stainless steel. 18 Part Number: 9291482 05/16

Section 4 Maintenance EXTERIOR CLEANING Not Never use an acid based cleaning solution on exterior panels! Many food products have an acidic content, which can deteriorate the finish. Be sure to clean the stainless steel surfaces of ALL food products. Clean the area around the unit as often as necessary to maintain cleanliness and efficient operation. Wipe surfaces with a damp cloth rinsed in water to remove dust and dirt from the outside of the unit. Always rub with the grain of the stainless steel to avoid marring the finish. If a greasy residue persists, use a damp cloth rinsed in a mild dish soap and water solution. Wipe dry with a clean, soft cloth. Never use steel wool or abrasive pads for cleaning. Never use chlorinated, citrus based or abrasive cleaners. Stainless steel exterior panels have a clear coating that is stain resistant and easy to clean. Products containing abrasives will damage the coating and scratch the panels. Daily cleaning may be followed by an application of stainless steel cleaner which will eliminate water spotting and fingerprints. Early signs of stainless steel breakdown are small pits and cracks. If this has begun, clean thoroughly and start to apply stainless steel cleaners in attempt to restore the steel. Gasket Maintenance Gaskets require daily cleaning to prevent mold and mildew build up and also to retain the elasticity of the gasket. Gasket cleaning can be done with the use of warm soapy water. Avoid full strength cleaning products on gaskets as this can cause them to become brittle and crack. Never use sharp tools or knives to scrape or clean the gasket. Gaskets can be easily replaced and do not require the use of tools or an authorized service person. The gaskets are Dart style and can be pulled out of the groove. Soak new gaskets in warm water to make them more pliable. Dry and press back into place. Casters Wipe casters with a damp cloth monthly to prevent corrosion. Defrosting Milk or Ice Cream dispensers require defrosting after 3/8 of frost forms. On/Off switch is located above the louver panel. Never use sharp objects or tools to clean or scrape ice/frost build up from the refrigerated cold pans. A puncture to the pan could cause irreparable damage to the refrigeration system. CLEANING THE CONDENSER COIL In order to maintain proper refrigeration performance, the condenser fins must be cleaned of dust, dirt and grease regularly. It is recommended that this be done monthly. If conditions are such that the condenser is totally blocked in a month, the frequency of cleaning should be increased. Clean the condenser with a vacuum cleaner or stiff brush. If extremely dirty, a commercially available condenser cleaner may be required. Failure to maintain a clean condenser coil can initially cause high temperatures and excessive run times. Continuous operation with a dirty or clogged condenser coil can result in compressor failure. Neglecting the condenser coil cleaning procedures will void any warranties associated with the compressor and cost to replace the compressor. Part Number: 9291482 05/16 19
