Installation
Location
Undercounter refrigerators 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. Take care when moving the equipment that nothing gets pinched between the unit and stationary objects. Sheet metal edges, although deburred, could cause cuts in certain situations.
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.
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
These 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. This will keep the unit from rolling or tipping.
Delfield™ ®
Electrical connection
Refer to the amperage data, 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 7’ (2.1 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.
If the supply cord is damaged it must be replaced before operating this equipment. Do not connect a damaged supply cord to a power source. The cord must be replaced by a qualified service personnel.
Operation
Be sure that fan guards are in place before operating. After the unit is connected to power it will automatically begin operating. With the door closed, the temperature of the cabinet should reach 36°F to 40°F (2°C to 4°C) in about one hour. The temperature control, located on the back panel inside the refrigerator, can be adjusted to meet the current conditions.
Temperature control instruction
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 door will hamper the unit’s ability to maintain optimum refrigeration temperature.
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 |
CAUTION |
employees. It is the owner’s responsibility to provide |
|
a container or outlet for drainage. |
Defrosting
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.
