Page 3: Receiving Your New Model
RECEIVING YOUR NEW MODEL Congratulations on your recent purchase of Continental Refrigerator superior food equipment products! When your shipment arrives, please thoroughly examine the shipping crate for any punctures, dents, or signs of rough handling. It is in your best interest to partially remove or open the shipping container in order to examine the model for any concealed damages which may have occurred during shipment. -

“removal of hood” section). VENTILATION The final location site of your air-cooled refrigerator or freezer must be able to provide a large quantity of cool, clean air. The refrigeration system operates most efficiently and trouble-free with cool, dry air circulation. Avoid locations near heat and moisture generating equipment such as stoves, ovens, cooking ranges, fryers, dish washers, steam kettles, etc., and also direct sunlight where temperatures can be in excess of... - Page 5 Important Note: To assure maximum operating efficiency, your new “SW” series model should be located where an unrestricted air supply can circulate underneath and behind the cabinet. For optimum performance, the cabinet must be installed on legs or casters (see “installing legs or installing casters” later in this section) and a min- imum of 3"...

Page 6: Floor Loads
For example, a 20 cubic foot refrigerator can hold approximately 700 pounds of product (35 x 20) and assuming the refrigerator itself weighs 300 pounds, the total combined weight of cabinet and product is approximately 1000 pounds. -
Page 7: Installing Legs And Leveling
INSTALLING LEGS AND LEVELING Your new “SW” series model is supplied with adjustable type legs for leveling purposes. Each SW27, SW48, SW60 and SW72 model has four leg mounting holes on its case bottom. Legs are packed in the accessory carton from which they must be removed and installed on the cabinet case bottom (see figure 2). -

FIGURE 3 CASTERS MUST BE TIGHT TO CABINET BOTTOM INSTALLING CONDENSATE EVAPORATOR No floor drains or plumbing connections are required since all models use an automatic condensate water evaporating system. All models utilize a unique hot air condensate water evaporating system which is completely self-contained and no further assembly or maintenance is required. -

OPTIONAL ELECTRIC CONDENSATE EVAPORATOR INSTALLATION REMOVAL OF DOORS AND DOOR ADJUSTMENT During installation, it may become necessary to remove the cabinet doors to facilitate passage through narrow doorways or hallways. To remove a door, swing the door to the open-door position (90°) and remove the two screws marked “a” (figure 5) while carefully holding the door open. -

DOOR ADJUSTMENT AND REMOVAL SELF-CLOSING HINGE MECHANISM MOUNTING For proper operation of the self-closing doors on all sandwich unit and prep models, the hinge mechanism must be mounted to apply tension in the direction shown in fig- ure 6. When the hinge is moved to the open-door position the hinge should be tension- free. -

208-230 VOLT, 60 HZ, 1 PHASE CONNECTION All 208-230 volt models are to be permanently connected and are provided with four (4) field wiring leads which exit the electrical console box located in the machine compartment rear, next to the compressor. The cabinet circuitry is 115 volts and the condensing unit is 208-230 volts in which the wiring includes a neutral and a mechanical ground. -
Page 15: Operation
OPERATION All cabinets must be given sufficient time to reach normal operating temperature before placing any food inside cabinet or pans (if equipped). Refrigerators are designed to maintain an ideal cabinet and pan temperature of 38°F to 40°F (3.3°C to 4.4°C) and approximately 1 hour of operation is required to reach this temperature. -
Page 16: Pizza Prep Temp Adjustment - Coldwall Rail
Before making any adjustments to the pressure control out of the factory design temperature range, please consult factory or a qualified refrigeration mechanic. UNDERCOUNTER REFRIGERATOR SYSTEM AND ADJUSTMENT All self-contained undercounter refrigerators are designed and factory set to maintain an average cabinet temperature of 38°F. The temperature control is accessible inside of the cabinet product compartment, on the right back wall next to the evaporator coil (see figure 7 for thermostat location). -
Page 17: Defrost Operation
DEFROST OPERATION All freezer models are equipped with an automatic, electric defrost system consisting of an electric evaporator coil heater, evaporator drain pan heater, automatic electric defrost time clock, and defrost high limit switch. The defrost system is time initiated by the time clock and temperature terminated by the high limit switch. -

10. When stacking a refrigerator and freezer, it is always best to place the freezer model on the bottom for maximum efficiency. The front grill which is attached to the stacking collar body is attached with easily removable thumbscrews and should be removed periodically for cleaning. - Page 21 To stack your models, the following instructions should be followed: 1. Decide which model is to be on “top” and which model is to be on “bottom". 2. On “top” model, remove both bottom rear cover screws on “bottom” model, remove both top joggle clip screws with bumpers.

Page 23: General Preventative Maintenance
Performance of the air cooled condensing unit located inside of the compressor machine compartment of your new model, depends exclusively upon the amount of air passing through the condenser fins. Your refrigerator or freezer will run more efficiently, consume less current, and provide a maximum of trouble-free service throughout its lifetime if the condenser is kept clean and an adequate supply of clean, cool air is provided at all times. - Page 24 MODEL # ____________________________Serial#________________ Notes: ______________________________________________________________ ____________________________________________________________________ ____________________________________________________________________ ____________________________________________________________________ ____________________________________________________________________ ____________________________________________________________________ ____________________________________________________________________ ____________________________________________________________________ ____________________________________________________________________ ____________________________________________________________________ ____________________________________________________________________ ____________________________________________________________________ ____________________________________________________________________ ____________________________________________________________________ ____________________________________________________________________ ____________________________________________________________________ ____________________________________________________________________ ____________________________________________________________________ ____________________________________________________________________ ____________________________________________________________________ ____________________________________________________________________ ____________________________________________________________________ ____________________________________________________________________ ____________________________________________________________________ ____________________________________________________________________ ____________________________________________________________________ ____________________________________________________________________ ____________________________________________________________________ ____________________________________________________________________ ____________________________________________________________________ ____________________________________________________________________ ____________________________________________________________________ ____________________________________________________________________ ____________________________________________________________________ ____________________________________________________________________...
