INSTALLATION: 500 CD, CR, CRR & OR

Location

To meet NSF standards, all units must be sealed to the floor.

Be sure the location chosen has a floor strong enough to support the total weight of the cabinet and contents. Contents fully loaded in this product line can weigh as much as 1500 lbs. 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. Do not pack the refrigerator so full that air cannot circulate. Be sure that the exterior of the unit has access to ample air. Avoid hot corners and locations near stoves and ovens.

Leveling

To level unit, simply lower the four adjustable rubber feet located under the unit to the floor and adjust until unit is level. A level cabinet will perform better because the drain will empty properly, the doors will line up with the frames correctly and the cabinet will not be subject to undue strain.

Plumbing

Self-contained models are standard with a condensate evaporator. If 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 and CAUTION operator’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.

Self-contained units have an ON/OFF switch located on the operators side. Simply turn the switch to ON to begin operation.

The power switch should be turned to OFF and the unit disconnected from the power source whenever performing service or maintenance functions.

OPERATION: 500 CD, CR, CRR & OR

On self-contained models, after turning the ON/OFF switch to ON, the unit’s compressor will begin operating. Delfield display cases are designed to maintain an operational temperature of 36°F to 40°F.

Do not load the storage area in a way that restricts the air flow. Overloading will result in the loss of temperature. Do not throw items into the storage area. The interior of the cabinet and the blower coil may be damaged by this type of neglect, which is not covered under your warranty.

These units use HFC-404A refrigerant, and have a lock-out high pressure limiting device. Under severe overloading conditions, in the

event of a condenser fan failure or a plugged or blocked condenser, this device may shut down

the refrigeration system. See page 17 for part number information if a replacement is required.
