Always have the serial number of your unit available when
calling for parts or service. A complete list of authorized
Delfield parts depots is shown on the back cover of this
manual.

The units represented in this manual are for indoor use only.

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 casters
are not bent.

6. Also open 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.

Uncrating the Equipment

First cut and remove the banding from around the crate.
Remove the front of the crate material, use of some tools will
be required. If the unit is on legs remove the top of the crate
as well and lift the unit off the skid. If the unit is on casters
it can be rolled off the skid.

INSTALLATION

Location

Be sure the location chosen has a floor strong enough to
support the total weight of the cabinet and contents. Units in
this product line can weigh as much as 1500 pounds when it
is fully stocked. 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 unit so full that air cannot circulate.
Take care not to block air flow to the fans and allow space
along sides.

Outside cabinet: Be sure that the unit has access to ample
air. Avoid hot corners and locations near stoves and ovens.
It is recommended that the rear of the unit be no less than
two inches from any wall, partition or any other object which
will restrict exhaust air flow.

Leveling

A level cabinet looks better and will perform better because
the cabinet will not be subject to unnecessary strain due to
doors not properly lining up with door frames.

Some models have casters for ease of cleaning underneath
and for mobility. It is important that the unit be installed in a
stable condition with the front casters locked before operating.
Locking the front casters after installation is the owner’s and
operator’s responsibility.

Electrical connection

A standard self-contained unit is provided with a power cord
and three-prong grounded plug.

The unit should be plugged into a receptacle with its own
circuit protection that matches the amperage of the plug.

Refer to the amperage data on page three or the
serial tag data and 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 to the unit.

The power supply must be disconnected
whenever performing maintenance or repairing
the equipment!

The unit must never be operated without the
louvered panel in place.

Built-in units

All self-contained units (MFSC, FFSC and RFFSC) are tested
at the factory to assure proper operation. The unit should not
be installed directly next to high heat generating equipment
(ranges, griddles, etc.).

These units are built into the counter from below and must
be supported from the bottom. The counter cut-out sizes and
power supply requirements are shown in the specifications on
page three. All refrigerators have drains located in the bottom
of the tank. An appropriate drainage area or container must
be provided by the customer. Be sure to place the unit so the
pressure control, located near the compressor, can be reached.

For installation of remote units (MF ,FF and RFF), consult a
refrigeration service company to connect refrigeration lines to
the remote condensing unit.

Self-contained refrigerated units (MFSC, FFSC
and RFFSC) require air flow to the compressor.
A louver is provided and must be installed in the
counter in front of the condenser. An equal size
opening at the rear of the cabinet must also be
provided to allow warm air to escape. Failure to
do so will void all product warranties.

Free standing units

All self-contained units (N, N6/10/14, NDF, NLFAC, SCF and
NSCF) are tested at the factory to assure proper operation. The
unit should not be installed directly next to high heat generating
equipment (ranges, griddles, etc.).

These units are free standing, either on legs or casters. The
power supply requirements are shown on page three. All free
standing units have drains located in the bottom of the tank.
An appropriate drainage area or container must be provided by
the customer.

Do not place the unit against a wall or any object that will
block air circulation through the condensing unit. If the unit
must be placed against a wall, leave a minimum of 2” of
space for air flow.

How to adjust self-leveling dispenser

Tools Needed: One small flat head screw driver; One Phillips

head screw driver.

1. Always wear safety glasses when adjusting your dispenser.
Also, lock brakes on mobile units before beginning.

2. Unload dispenser and remove stainless steel load tray by
lifting straight up and set it aside (see fig. 1).

(figure 1) Sample unit

3. Use small regular screw driver to loosen each retainer

mounted on stainless steel rod at top of each elevator
housing.

4. To remove
elevator housing,
lift housing
straight up to
clear the stud on
unit base. Then
gently swing the
bottom of the
housing towards
the inside of the
unit and pull
housing out of
the unit (see fig.

2). Lay housing
on flat surface.

(figure 2) Remove elevator housing

5. Use Phillips head

screw driver to
remove front panel
on the elevator
housing (see fig. 3).

6. If carrier is riding
too high, you need
to remove springs.
With carrier all the
way to the top,
gently disengage
one spring at a
time, unhooking

(figure 3) Remove front panel

bottom loop out of
carrier bracket (see
fig. 4). Remove as
many springs as
necessary.

If carrier is riding too

low, you need to add
springs. With carrier
all the way to the top,
gently engage one
spring at a time by
hooking bottom loop
of spring into carrier
bracket. Add as many

(figure 4) Remove or add springs

springs as necessary.

7. When finished, put elevator housing back in unit and put
stainless steel load tray back on elevator housings. Load
unit to test dispensing level. If spring adjustment does
not position carrier properly, repeat procedure #6 trying
different springs. If this does not work, a different set
of springs may be required. To order, call The Delfield
Company Parts and Service Department at 800.733.8829

8. If level is appropriate, put front panels back on and
tighten retainer.

CAUTION: Dispenser should not be operated
with front panels off elevator housing.

NOTE: When adjusting the elevators make sure each have the

same number and size of springs connected to the carrier on
both sides. This will prevent the load tray from binding.
