The LD1C1A-5 and LD1C1A-10 are installed individually in an area approximately 3-1/2 feet x 6 feet or 3-1/2 feet x 11 feet respectively. Adjustable glide feet are provided on each merchandiser for leveling the merchandiser. Swivel plate mount casters with brakes are optional in lieu of glide feet. The merchandisers have continuous wrap-around heated glass handrails. The 5-foot model has three deck pans and the 10-foot model has six deck pans. Adjustable wire racks are available as an option. All merchandisers are factory charged with refrigerant and tested in the factory. NOTE: All compressor and base service valves are shipped in the open (operating) position. 3

4 Installation and Operation Manual 2.1. Components Electrical All field installed wiring must comply with the NATIONAL ELECTRICAL CODE AND LOCAL ELECTRICAL CODES. The merchandiser is provided with power cord(s) that have a male plug that is shipped loose for installation in the store. There is/are also matching female receptacle(s) that are shipped loose. To gain access to the inside of the electrical control panel, remove the control panel cover. Ensure that the correct input voltage is being supplied to the merchandiser. The power supply for each system is 4 wire 208 VAC that includes two 208 VAC hot legs, a neutral wire and a ground wire (Figure 2-2). All 10 foot models have two separate refrigeration systems with two separate power supplies. 4 WARNING! ALL MERCHANDISERS MUST BE PROPERLY GROUNDED Ensure that the proper wire conductor size and branch circuit protection are employed on each electrical circuit for safe operation. Evaporator Fan Motor The evaporator fan motor is permanently oiled for the life of the motor and requires no periodic maintenance. The fan motor is wired according to the wiring diagram and must run continuously to circulate air through the evaporator coil and air ducts during defrost to remove frost and ice that has accumulated during the refrigeration cycle. Anti-Condensate Heaters Anti-condensate heaters are installed in the merchandiser to prevent surface condensation or frost from forming on specific areas of the merchandiser. All insulated glass assemblies contain three 3/16" thick glass panels with two 1/4" air spaces in between the glass panels. Heat is applied on the inside surface of the exterior pane of each insulated glass assembly. Anti-condensate heaters are energized only when the merchandiser is operated in the low temperature mode. Defrost Heater Figure 2-2. Receptacle for Four-Wire 208 VAC A standard 115 volt defrost heater is located inside the fan plenum and is attached to the front face of the evaporator coil. The defrost heater is designed to provide evenly distributed heat to the evaporator coil to ensure adequate defrosting of the evaporator coil during defrost cycles. The defrost cycle is time initiated by the electronic controller

5 Self-Contained Spot Merchandiser that stops the refrigeration cycle and energizes the defrost circuit to energize the defrost heater. The defrost cycle is terminated either by a temperature sensor connected to the electronic controller or failsafe time returning the merchandiser into refrigeration mode. A defrost heater safety limit thermostat (Klixon) is wired in series with the defrost heater that opens if the temperature exceeds 70 F. Expansion Valve The expansion valve furnished with the merchandiser was selected to provide maximum coil operating efficiency. The expansion valve superheat is preset at the factory. Should it be necessary to adjust the superheat, place a thermocouple on the suction line near the expansion valve bulb using a plastic wire tie. Measure the suction line pressure at the suction line service valve (Figure 2-3). Convert the suction line pressure measured at the suction line service valve to saturated evaporator temperature using a refrigerant pressure-temperature conversion chart. The difference between the thermocouple temperature and the saturated evaporator temperature is the superheat. (Use average superheat when the expansion valve is hunting) Do not attempt to set the expansion valve superheat until the merchandiser has reached steady state operating temperature. Never open or close the expansion valve more than a 1/4 turn between adjustments and allow a minimum of 15 minutes or more between valve setting adjustments. Superheat should be set between 6-8 F. Refrigerant Piping The suction line piping size is 1/2" outside diameter and the liquid line piping size is 3/8 outside diameter. The liquid line and suction line are connected to service valves on the base of the condensing unit. All normal service except compressor replacement can be done without removing the condensing unit. Liquid Line / Suction Line Heat Exchanger A liquid line / suction line heat exchanger is standard on these merchandisers. It helps increase operating efficiency and reduces possible flood-back to compressors. Condensing Unit This dual temperature merchandiser incorporates a Copeland condensing unit with a KALB-015E-CAV model Copeland compressor. The condensing unit is equipped with a preset crankcase pressure regulator set at 30 psig to protect the compressor from overload after defrost termination and when operating in medium temperature mode. The merchandiser uses a condensate evaporating pan with an electric heater that is used to evaporate defrost drain water into the air. The low wattage evaporation pan heater operates to evaporate defrost drain water between defrost cycles whenever the pan fills with water. Refrigerant The refrigeration system contains 5 pounds of R-404A (HFC) refrigerant. If the unit should require recharging, the system must be evacuated and re-charged with 5 pounds of R-404A refrigerant. The refrigerant charge for this merchandiser is very critical. If the merchandiser should need to be recharged, an accurate charging device must be used. Refrigerant should not be released into the atmosphere and must be reclaimed if removed from the refrigeration system. 5

6 Installation and Operation Manual 3. Receipt, Preparation, Unpacking and Installation This section covers the receipt, preparation, unpacking and installation of the merchandiser. NOTE: Read all instructions carefully before beginning installation Receipt All equipment should be examined for shipping damage before and during unloading. If there is any damage: The carrier should be notified immediately and an inspection requested. The delivery receipt must note that the equipment was received damaged. If damage was concealed, the customer should contact the carrier immediately or no later than three days following delivery. A claim must be filed with the carrier by the consignee for all damage. NOTE: All claims for shortages must be submitted within 10 days after receipt of shipment Preparation Prepare the installation area as follows: Clean the area where the merchandiser is to be installed. Verify the area is at least 15 feet away from any outside entrances or heating and cooling outlets. Ensure that floor structural loading will support the merchandiser including the merchandiser contents. Ensure correct power is available. Refer to merchandiser power input requirements located in the Electrical Data section of this manual Unpacking When unpacking: Ensure the evaporator cover is installed correctly with the deck pans installed. Move the merchandiser into position, install, and perform the operational checkout procedures following the instructions in this manual. NOTE: For shipping purposes, two compressor mounting bolt nuts (right rear and left front) have been tightened to prevent damage to the condensing unit during shipment. THESE NUTS MUST BE LOOSENED BEFORE START UP so that the compressor can float freely on the supporting springs. To gain access to the compressor mounting bolt nuts, remove the lower front louver panel and the right end cover Installation 6 Ensure all preparation for installation, as outlined in the above paragraphs, has been fully complied with and is complete. Allow a minimum of 18 inches between the rear and front of the merchandiser and store walls and/or other merchandisers. This space reduces the possibility of surface condensation and compressor overheating. 4. Operation Merchandise should not be placed in the merchandiser until the merchandiser is at steady state operating temperature. The merchandiser should not be loaded with product above the load limit line located on the top of the inside back panel. If this load limit line is exceeded, cooling performance will be adversely affected and will result in warm product temperatures as well as increased operating costs. Each 5 foot model merchandiser and each 5 foot section of the 10 foot model merchandiser contain two electronic controllers used to control discharge air temperature and defrosting (two for the left 5 foot section and two for the right

7 Self-Contained Spot Merchandiser 5 foot section). The discharge air sensor is located inside the rear discharge air duct. The settings for low temperature and medium temperature are preset in the electronic controller and no adjustment is required after connecting power to the merchandiser. CAUTIONS: Air discharge and return flues must remain open and free of debris or obstructions at all times to provide proper refrigeration and air curtain performance. Do not allow any product, signs, debris, etc., to block return air grills. Do not use any non-approved shelving, display racks, or any accessory that could disrupt air curtain performance. NOTE: Electric defrost is standard on these models and evaporator fans run continuously Cleaning As a general rule, always use mild soap and water to clean the merchandiser. Special precautions must be taken when cleaning some components of the merchandiser. Exterior surfaces should be cleaned with warm water and mild soap to protect and maintain the finish. Do not use cleaners containing abrasive materials or ammonia that will scratch or dull the finish. The waste outlet should be flushed with water following each cleaning. Interior surfaces may be cleaned with most mild soap formulas, ammonia based cleaners, and sanitizing solutions with no harm to the surface. WARNING! ALWAYS DISCONNECT POWER DURING THE CLEANING PROCESS. CLEANING THE MERCHANDISER WITH ELECTRICAL POWER APPLIED IS A SHOCK HAZARD THAT MAY CAUSE SERIOUS INJURY OR DEATH. CAUTION: DO NOT USE HOT WATER ON COLD GLASS SURFACES. This could cause the glass to shatter and result in personal injury. Glass fronts and ends should be warm before applying hot water. Do not use materials or methods listed below to clean the merchandiser. The warranty will be voided if these products or cleaning methods are used that causes rust to form on the stainless steel surfaces or any other parts of the equipment. On unpainted stainless steel surfaces (they may cause rust to form), products containing: Chlorine Chloride ion Any cleaner containing bleach On any interior surfaces because the surface may become damaged: Solvents Oils Acidic-based cleaners Abrasive cleaners and scouring pads because these will mar the finish Steam or high pressure systems to clean the merchandiser because seals may be broken resulting in leaks To ensure minimum maintenance cost, the merchandiser should be emptied and thoroughly cleaned every three months. The exterior should be cleaned weekly. The waste outlet should also be checked and cleaned weekly. Follow the previous general cleaning of the interior and exterior parts. Do not use a water hose to clean the evaporator or tub of the merchandiser. 7

8 Installation and Operation Manual CAUTIONS: DO NOT FLUSH THE MERCHANDISER WITH WATER. This merchandiser is not connected to a drain system and has a defrost water evaporating pan with only a limited volume capacity. The merchandiser should have at least 18 clearance from any wall or other obstruction in order to operate properly. NOTE: Do not stack anything in front of the intake or exhaust louvers that may block airflow on the merchandiser. Selfcontained merchandisers draw in air from the rear and discharge air toward the front. Blocking airflow to the louvers will cause the merchandiser to overheat and shut down. Cleaning Condensing Units Once a month, use a vacuum cleaner to remove any lint or other debris that may have collected on the entering air side of the condenser coil. Cleaning the Honeycomb The honeycomb should be cleaned every 6-8 months, depending on store conditions. The honeycomb may be cleaned with a vacuum cleaner or may be removed and be washed with soap and water. The honeycomb must be completely dry before reinstalling it on the merchandiser if cleaned with soap and water Electrical Connections All field connections are made inside the electrical control panel. Ensure that the proper power supply and voltage are supplied to the merchandiser. Check the merchandiser data plate for the required input voltage. Field wiring must be installed in accordance with local and national electrical codes. The electrical control panel is located: For the 5 foot model merchandiser, at the left end of the merchandiser. For the 10 foot model merchandiser, at each end of the merchandiser for each refrigeration system. WARNINGS! ALL MERCHANDISERS MUST BE PROPERLY GROUNDED. ENSURE KICK PLATES DO NOT COME IN CONTACT WITH THE MERCHANDISER ELECTRICAL WIRING. LIVE ELECTRICAL WIRING THAT COMES IN CONTACT WITH THE MERCHANDISER IS A SHOCK HAZARD THAT MAY CAUSE SEVERE INJURY OR DEATH BY ELECTROCUTION. ALWAYS DISCONNECT ELECTRICAL POWER AT THE MAIN DISCONNECT WHEN SERVICING OR REPLACING ANY ELECTRICAL COMPONENT. THIS INCLUDES, BUT IS NOT LIMITED TO COMPONENTS INCLUDING FANS, HEATERS AND CONTROLLERS. FAILURE TO DISCONNECT ELECTRICAL POWER MAY RESULT IN PERSONAL INJURY OR DEATH.
