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
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.
CAUTION
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.
