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 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.
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
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! 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 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 responsibility to provide
a container or outlet for drainage.
Electrical connection
Refer to the amperage data on the specifications page, 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 6’ (1.8 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.
Stacked 400 series electrical connection
Models 406 and 407 may be stacked using a stacking collar,
Delfield model 409. In this case two 6’ (1.8m) long grounded
supply cords and plugs are standard. Simply plug them in to
begin operation.
For Cord Connected Units - Risk of Electric Shock.
This equipment has two power supply cords.
Unplug all cords before moving or servicing this
equipment.
