Receiving And Inspecting The Equipment
Even though most equipment is shipped crated, care should be taken during unloading so the equipment is not damaged while being moved into the building.
1. Visually inspect the exterior of the package and skid or container. Any damage should be noted and reported to the delivering carrier immediately.
2. If damaged, open and inspect the contents with the carrier.
3. In the event that the exterior is not damaged, yet upon opening, there is concealed damage to the equipment notify the carrier. Notification should be made verbally as well as in written form.
4. Request an inspection by the shipping company of the damaged equipment. This should be done within 10 days from receipt of the equipment.
5. Check the lower portion of the unit to be sure legs or casters are not bent.
6. Be sure to check the compressor compartment housing and visually inspect the refrigeration package. Be sure lines are secure and base is still intact.
7. Freight carriers can supply the necessary damage forms upon request.
8. Retain all crating material until an inspection has been made or waived.

Installation
Location
Units represented in this manual are intended for indoor use only. Be sure the location chosen has a floor strong enough to support the total weight of the cabinet and contents. Reinforce the floor as necessary to provide for maximum loading.
For the most efficient refrigeration, be sure to provide good air circulation inside and out.
Inside cabinet: Do not pack refrigerator so full that air cannot circulate.
Outside cabinet: Be sure that the unit has access to ample air. A minimum space of 3” (7.6cm) at the back of the unit and 1” (2.5cm) at the top and sides is required to conform to Underwriters Laboratories’ standards. On undercounter units it is imperative that the proper air flow be maintained. The refrigeration system is designed so air will flow under the unit, over the compressor/condenser area, and out at the top rear of the unit. Avoid hot corners and locations near stoves and ovens.
Any restriction of the proper air flow outlined above, total or partial, will void the warranty on the unit.
Leveling
A level cabinet will perform better because the drain pan will drain properly, the doors will line up with the frames and the cabinet will not be subject to undue strain.
All four legs are adjustable. Adjust each leg until the unit is stable and level left to right. If necessary adjusting the front legs slightly higher than the rear by about 1/8” (0.3cm) will help the doors remain closed.
If the unit is supplied with casters, no adjustments are available. Ensure the floor where the unit is to be located is level.
Never stand on the unit! Doing so may result in bodily injury. They are not designed to hold the weight of an adult and will collapse if misused in this manner.
Stabilizing
Some models are supplied on casters for your convenience, for ease of cleaning underneath and mobility.
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.
Plumbing
Self-contained models are standard with a condensate evaporator. If, for some reason, a unit does not have a condensate evaporator, or the evaporator fails, the unit’s drain must have an outlet to an appropriate drainage area or container.
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.
Electrical connection
Refer to the amperage data on page 3, the serial tag, your local code or the National Electrical Code to be sure the unit is connected to the proper power source. A protected circuit of the correct voltage and amperage must be run for connection of the line cord, or permanent connection to the unit.
A 6’ (1.8 m) long grounded supply cord and plug are provided with standard units. Simply plug the unit in to begin operation.
The thermostat must be turned to OFF and the unit disconnected from the power source whenever performing service, maintenance functions or cleaning the refrigerated area.

WARNING
Caster Installation
1. Carefully place the unit on its back (see illustration at right).
2. Remove legs by unscrewing them in a counter clockwise direction.
3. Located on each end of the compressor channel are 4 hex head screws, for a total of 8 screws. Remove them. 8 additional screws are provided with your casters.
4. 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 hex head screws and tighten. Repeat with the other locking front casters.
5. Repeat step 4 with the non-locking casters in the rear of the unit.
6. Carefully lift the unit upright.
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.
2”, 3” and 5” Caster and Leg Mounting Detail
A universal bolt hole pattern is provided on the bottom of the cabinet. It will accommodate any leg or caster. Simply line up the plate holes with the corresponding cabinet holes.

Refrigerator Temperature Control Operation
After the unit is connected to power it will automatically begin operating. With the doors closed, the temperature of the cabinet should reach 36°F to 40°F (2°C to 4°C) on refrigerators in about one hour.
A thermostat located in the evaporator housing on interior rear of the unit, controls the temperature in the box. The factory setting for the control is “4” and maintains about 38°F (3°C) in the box. Set toward “1” for higher temperatures and toward “7” for lower temperatures.
Continuous opening and closing of the doors will hamper the unit’s ability to maintain optimum refrigeration temperature.
Refrigerators defrost automatically with every cycle of the compressor. The water generated is routed to a pan on the rear of the unit and is evaporated by the heat given off by the compressor.
Service Alert
During normal operation the evaporator fan may cycle and/or pulse independently of the compressor. Consult the service manual or contact Technical Support at 1-888-732-2446 if you are unsure of the proper function.
