It is engineered for air-conditioned stores with a maximum ambient of 75° F and 50% relative humidity. When selecting the location for placement of this case, avoid the following conditions: Excessive air movement • Doors • Air-conditioned vents • Other air sources Excessive heat • Windows • Sun • Flood lamps 8 feet or less from the product • Other heat sources Crate Removal Move case as close as possible to its location. Remove all crating and shipping braces above the shipping pallet. Loosen the plastic dust cover from the pallet, but leave cover over the case to protect it while removing the case from the pallet. Carefully, lift case up and off the pallet. Remove dust cover. Installation hardware ships in an installation packet located inside the case. Joining Lineups 1. Begin all lineups leveling from the highest point of the store floor. 2. Remove front and rear toe kicks by removing screws on all sides. Set and level first case. 3. Apply foam tape to facing ends of lineup. Level second case to first case and seal with a good grade silicone on all edges of each case. 4. Line up bottom boltholes in lower toe kicks (bolts for these are located in the installation packet inside the case) and line up bolt stud located in top rear strut with bolthole in adjoining case. Slide cases together. Insert lower bolts and place nuts on bolts. Tighten securely. THE FRONT OF THE CASES MUST BE FLUSH! 5. A top joining plate is also located in the canopy of the case. Ensure that case is properly leveled so that the screw holes in this plate align over the screw holes in the adjoining case. Shim as necessary. 6. Screw in top plate and ensure all bolts are fastened tightly. 7. Seal all seams. Use metal U-channel located inside case to seal and cover where interior case beds join. Compressor The 6', 8', 10 and 12' Self-Contained cases are equipped with a shipping block under the compressor. This block must be removed upon installation. Loosen all four nuts on the compressor hold down screws. Lift or pry the compressor up and remove the shipping block. DO NOT retighten screws, as the compressor should be left free to float on the spring mounts. FAILURE TO REMOVE THE SHIPPING BLOCK WILL RESULT IN EXCESSIVE NOISE, REFRIGERANT LEAKS AND WILL VOID WARRANTY PROTECTION. Case Exterior Loading These cases are not designed for excessive external weight. DO NOT WALK ON THE TOP OF THE CASES. Walking on top of cases could cause personal injury and damage to the case. Leveling To ensure proper operation of the refrigeration system and drainage of the condensate, the case MUST BE LEVEL. Use a carpenter level to level front to back and side to side. Shim as necessary. Drain, Electrical and Refrigeration Connections on Remote Cases 1. Drains are located in the center of the case. Connect PVC drains to existing floor drains. Provide as much downhill slope as possible and avoid long runs of drain lines. Do not install condensate drains in contact with non-insulated suction lines in order to prevent condensate from freezing. Install the 1" PVC trap, which is provided with the case. All drains must be trapped. 2. Electrical connections are made through the power supply box of each case, which can be accessed by removing the back panel above the toe kick. The power supply is located in the raceway as shown to the right. Voltage requirements and component amperes can be found in the electrical section of this manual, but always check the data tag located on the exterior of the case. Case must be grounded. 3. Refrigeration connections will be made through the refrigeration stub up located on the customer left side of the case (see mechanical view). See refrigeration information section for caseloads and recommended settings. Refrigeration lines may be headed together for all cases in a lineup, if desired, by lines through the access area under the case. Seal all access holes with a good grade silicon or foam tape to prevent recirculation. All lines must be correctly sized. For proper refrigeration performance, PRODUCT MUST NOT BE PLACED IN A POSITION WHERE IT MAY AFFECT THE AIR CURTAIN. Air discharge and return air vents must remain unobstructed. Glass Adjustment Lift Glass is installed at the factory with the case perfectly level, if adjustments need to be made to align the glass first check to insure the case was properly leveled during installation. NOTE: This is a 2-person operation. One person must hold the glass at all times. 1. Lift the glass to its highest position as shown in drawing to the right. 2. Loosen allen screws. (See profile next page.) 3. Starting at the right side, tap the wedge with a #2 standard screwdriver. Repeat procedure on the left side. Continue working right to left until the wedge recesses into the aluminum extrusion. EXTREME CARE MUST BE TAKEN NOT TO TAP THE WEDGE TOO HARD. 4. Slide the glass right or left as needed. 5. Tighten the right allen screw while holding the left side of the glass firmly. Be careful to keep the glass level. 6. Tighten the remaining allen screws. 7. Lower glass into position. Repeat as necessary until glass is completely level. NOTE: the entire glass clamp and glass can be moved sideways by loosening the allen screws that are located in the glass clamp hinges. Humidifier System This optional feature is installed at the factory. Initial hook-up is as follows: 1. Read installation/service guide, which accompanies unit. 2. If connecting a lineup, which shares a common control system, connect companion case dis charge lines. 3. For all cases, connect water supply. NOTE: It is recommended that a pre-filter be added to the water supply. 4. Check for leaks. Adjust water pressure as needed. See manufacturers installation guide for further information. Doors Rear load doors are shipped inside the case. Push top of doors all the way into top door tracks. Push bottom of door over bottom door tracks and lower over tracks. Doors are labeled inside and outside for easy installation. Optional Shelving Shelves are shipped separately. To place shelving, hold shelf straight and fit brackets straight into channel.

Shelf lights will not operate if plugs are not fully seated. NOTE: If the shelf light is not in use, the plug attached to the receptacle must be fully seated. Installation Checklist Before supplying electrical power and starting case check the following: 1. Compressor Area (For Self-contained cases). Remove shipping block on units with semihermetic compressors. Check location of controls. 2. Evaporator Area. Check to ensure evaporator fan pressure plates are secure and in proper position NOTE: Hinged portion of pressure plates are secured for shipping with mounting screws. Screws do not have to be removed for case operation but must be removed to use hinge. 3. Lighting System Check to ensure male plugs are completely inserted in female sockets and that all lamps are securely seated in light fixture. 4. Case Leveling Visually check case. If lift glass is out of adjustment or case looks out of square, use a carpenter's level and shim as needed. After supplying power to the case and starting unit: 1. Check to ensure all fans are operational. 2. Check all lights. 3. Check case temperature and adjust thermostat as needed. See refrigeration section of this manual for case settings. Refrigeration Information Case Operation Electronic Thermostat Refrigeration The refrigeration in this case is thermostatically controlled. The case refrigerates until the cut out point on the thermostat is reached. The thermostat opens, cutting power to the liquid line solenoid. The compressor continues to run, the system pumps down causing the pressure switch to open, cutting power to the compressor. Note: Some cases may be ordered with EPR valves to control case temperature. For proper refrigeration performance, PRODUCT MUST NOT BE PLACE WHERE IT WILL AFFECT THE AIR CURTAIN. The electronic thermostat is located at the rear of the case in the electronic raceway. The thermostat is equipped with a liquid crystal display providing a constant readout of the sensed temperature. NOTE: The LCD display will be blank during defrost. A touch keypad that allows the users to select the set point temperature, differential and the heating /cooling modes. Defrost This case is equipped with an OFF CYCLE defrost system. The timer cuts the power to the liquid solenoid. The unit stays in off cycle defrost until the defrost timer re-energizes the liquid solenoid. NOTE: The evaporator fan runs continuously.
