Serial Number Location
The serial number on 400 series compact refrigerators and
freezers is printed on the right side of the interior back wall.
The serial tag on 4000 series compact refrigerators and freezers
is located either on the left upper sidewall inside the cabinet or
under the top nosing directly above the door when the door is in
the closed position (right hand door when there are two doors).
Always have the serial number of your unit available when calling
for parts or service. A complete list of authorized Delfield parts
depots is on www.delfield.com.
This manual covers standard units only. If you have a custom
unit, consult the customer service department at 1-800-7338829

Receiving And Inspecting The Equipment
Even though most equipment is shipped crated, care should
be taken during unloading so the equipment is not damaged
while being moved into the building.
1. Visually inspect the exterior of the package and skid or
container. Any damage should be noted and reported to
the delivering carrier immediately.
2. If damaged, open and inspect the contents with the
carrier.
3. In the event that the exterior is not damaged, yet upon
opening, there is concealed damage to the equipment
notify the carrier. Notification should be made verbally as
well as in written form.
4. Request an inspection by the shipping company of the
damaged equipment. This should be done within 10 days
from receipt of the equipment.
5. Check the lower portion of the unit to be sure legs or
casters are not bent.
6. Be sure to check the compressor compartment housing
and visually inspect the refrigeration package. Be sure
lines are secure and base is still intact.
7. Freight carriers can supply the necessary damage forms
upon request.
8. Retain all crating material until an inspection has been
made or waived.

CAUTION
Installation
Compact Refrigerators and Freezers Service and Installation Manual
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.
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 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 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.
CAUTION
Unplug all cords before moving or servicing this
equipment.
Never stand on the unit! Doing so may result in bodily
injury. They are not designed to hold the weight of an
DANGER
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.
