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. If the model is damaged, it must be noted on the delivering carrier's

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" on each side and rear of the cabinet must be provided (see figure 1a). Your model has been designed to operate sufficiently without legs or casters and

FIGURE 1b MINIMUM CLEARANCE DIMENSIONS WITHOUT LEGS FLOOR LOADS The floor at the final location site must be level, free of vibration and strong enough to support the total combined weights of your new model plus the maximum product load which might be placed into it. A fully loaded reach-in model may reach 2,000 - 3,000 pounds. To estimate the possible product load weight, assume that each cubic foot of storage space weighs approximately 35 pounds. Multiply 35 pounds by the amount of cubic fee

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). In order to install the legs, carefully tip the cabinet rearward adding four (4) 2" wood blocks underneath and simply screw the threaded leg studs into the case bo

Important Note: It is extremely important that your new model is perfectly level for proper operation. If it is not level, the following adverse conditions will become apparent: 1. The door(s) will not be properly aligned and consequently will not provide a good seal. 2. You model will run excessively due to improper door seal(s). 3. An excessive amount of ice will accumulate inside the cabinet, around the door opening(s) and especially on the finned evaporator coil. If allowed to continue, i

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. In some adverse conditions such as high ambient temperature, high humidity, extremely heavy usage, frequent loading for prolonged p

FIGURE 4 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. Care must be taken to hold the door fully open during the screw removal since the top hinge is spring loaded and may

FIGURE 5 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. However, when the hinge is moved back into the closed position, it should snap back. Caution should be taken when checking the spring loading as the hinge could sna

REMOVAL AND REPLACEMENT OF HINGE MECHANISM To remove the hinge mechanism from the door, remove the door from the cabinet as explained above. As shown in figure 6, remove the hinge plate from the hinge mechanism by removing the hinge pin screw. Also remove the horseshoe spring. 1 Reinstall the hinge pin screw only partially leaving about /8" of exposed screw threads. Now, the hinge mechanism mounting screws can be removed thus allowing the mechanism to be removed by pulling on the hinge pin sc

Important Note: Never use harsh detergents, cleaners, scouring powders or chemicals when cleaning your model. Failure to dry the interior surfaces after cleaning may result in a streaking or staining of the metal. Complete cleaning procedures and precautions are listed in the “periodic cleaning procedure” under the maintenance section. START-UP PROCEDURE ELECTRICAL CONNECTIONS To insure proper operation, your new model must be connected to an individual circuit that can supply the full volta

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. This wiring should be connected to the appropriate power source by a qualified electrician and must confor

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. During pull-down of open top models, pans should be in place and top lid should be kept closed. Freezers are designed to maintain an ideal cabinet temperatu

PIZZA PREP TEMP ADJUSTMENT - COLDWALL RAIL If an adjustment is necessary to maintain the coldwall rail temperature, a pressure control is located behind the front grill which controls the compressor operation and the temperature range of the rail. The factory recommended settings for this low pressure control are the following: CUT IN = 45# DIFFERENTIAL = 20# Before making any adjustments to the pressure control out of the factory design temperature range, please consult factory or a qualifi

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. The time clock is preset for three (3) defrost periods per day at eight (8) hour intervals and a fail safe cut-off time of 20 minutes. Please note t
