CAUTION
Operation
After turning the ON/OFF switch to ON the unit’s compressor
will begin operating. Delfield refrigerated bases are designed
to maintain an operational temperature of 36°F to 40°F.
Temperature in the salad top and refrigerated rail opening is
33°F to 41°F with pans recessed 3” on a standard wrapped
refrigerated rail or flush with the LiquiTec option at 86°F
ambient room temperature. Freezer bases are designed to
maintain an operational temperature of 0°F.
Do not place hot pans on/against the blue ABS
liner. Do not throw items into the storage area.
Failure to heed these recommendations could
result in damage to the interior of the cabinet or
to the blower coil.
Overloading the storage area, restricting the air flow, and
continuous opening and closing of the doors and drawers
will hamper the units ability to maintain operational
temperature.
Refrigerated rail units
Product in the rail should be removed to the refrigerated base
at the end of the day. This allows you to turn the
rail off at night to save energy and the rail will have
time to defrost as needed. It also helps maintain
product quality. The standard wrapped refrigerated
units are controlled by the pressure control which
is set to maintain the proper rail temperature an on/off switch
is also provided for the rail and is required to be shut off at
night. The rail switch shuts off the rail only. With a LiquiTec
rail a thermostat is provided to maintain rail temperature as
well as the rail on/off switch. The LiquiTec rail is required to
be shut off at night as well to allow for defrosting. To ensure
product quality in the rail it is recommended that product be
rotated every four hours.
If adding any item to the unit, be sure to keep
in mind the location of the refrigeration lines on
wrapped rail units. A refrigeration leak in a rail
is extremely difficult and costly to repair. In some
cases it cannot be repaired at all.
Installation
Location
Be sure the location chosen has a floor strong enough to
support the total weight of the cabinet and contents. A
fully loaded 72” long model may weigh as much as 1500
pounds! Reinforce the floor as necessary to provide for
maximum loading.
It is very important to allow for proper air flow, both
inside and outside.
Avoid hot corners and locations near stoves, ovens and
other pieces of cooking equipment.
It is recommended that the unit be installed
no closer than 1” from any wall. Do not install
the unit near any combustible material or
object affected by heat or moisture.
Leveling
A level cabinet looks better and will perform better
because the drain pan will drain properly, the doors will
line up with the frames properly, and the cabinet will not
be subject to undue strain.
A unit on legs will have an adjustable bullet foot on each
leg, adjust each for a level unit. A unit on casters will not
be adjustable. Be sure the unit is on a level floor, make
necessary changes to the floor for proper level.
Lock all front casters to ensure the stability of the unit.
Plumbing
Self-contained models are standard with a condensate
evaporator. If, for some reason a unit does not have a
condensate evaporator, or if the evaporator fails, the unit’s
drain must have an outlet to an appropriate drainage area or
container. A refrigerated rail will have a 1" drain which will
need to be run to an appropriate floor drain or container.
The drain will be stubbed to the bottom of the machine
compartment. Either run drain to a floor drain or add a valve
to the base of the machine compartment and drain the rail to a
container when convenient. The LiquiTec option will NOT have
a drain available.
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 pages 3-5, 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 of the unit.
Self-contained units with a cord and plug have an ON/OFF
switch located directly behind the louvered panel covering
the compressor section. Simply turn the switch to ON to
begin operation.
The power switch must be turned to OFF and
the unit disconnected from the power source
whenever performing service or maintenance
functions.
Never operate the unit without the louvered panel
in place!
If electrical receptacles are to be mounted in the unit’s
backsplash, they must be wired independently from the
existing unit wiring.
