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. On
all 400 and 4000 Series equipment, (for 4500 Series equipment
door and drawer models see below), 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.
4500 Series equipment door and drawer models: These units
have Delfield’s “front-breathing” design. They may be installed
flush against a wall or built into a counter as required. The
louver at the floor level must be kept completely clear of any
obstructions. Proper operation of these models is dependent on
air being able to flow freely through the front louver. The louver
at the back of the unit is not necessary for proper operation, but
any air flow through is beneficial.
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 drawers or 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 door or
drawers 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 or its drawers! 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 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.
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.
