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
7. Freight carriers can supply the necessary damage forms
8. Retain all crating material until an inspection has been
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.
visually inspect the refrigeration package. Be sure lines
are secure and base is still intact.
Milk, Ice Cream & Milk & Ice Cream Dispensers Service and Installation Manual
Installation
Location
These units 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. 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 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!
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.
The unit must never be operated without the
louvered panel in place.

Milk, Ice Cream & Milk & Ice Cream Dispensers Service and Installation Manual
Operation: N, N6/10/14, NDF, NLFAC, MF & MFSC Series
N, N6/10/14, NDF, NLFAC and MFSC Series milk dispensers
are set at the factory to maintain temperatures between 36°F
and 40°F. No further adjustment should be necessary. To begin
operation on self-contained models, plug the electrical supply
cord into a receptacle with the correct voltage. Remote models
will require a connection to a separate refrigeration system.
Loading: N, MF & MFSC Series
To load, place a complete layer of cartons or bottles standing
upright on the load tray. Then place a divider tray on top of
this layer, then another layer of cartons or bottles on this tray,
then another tray and another layer, etc. As each additional
tray is loaded, the elevators gradually lower. The last layer
may be placed on top without the use of another tray. When
loading the average tall half pint bottles, four layers may be
loaded into each compartment standing upright and the fifth
layer laying down.
It is very important to use the divider trays
provided between each successive layer of
contents to assure the correct balance of the
load and the proper action of the elevating
mechanism.
Wire racks, when used, should be loaded completely. When
placing one rack on top of the other, be sure the stacking lugs
are properly aligned.
Loading: N6/10/14 Series
These cabinets are designed to dispense 13” x 13” x 11” high
(maximum dimensions) dairy cases. Place one case loaded
with milk on the carrier and then place a second case loaded
with milk on top of the first case. Press down on the cases
leaning them toward the retaining bracket located under the
top lid track, then gradually release pressure on the cases
so that the top edge of the case engages with the retaining
bracket.
The elevating mechanism is designed to keep the contents
several inches below the top of the cabinet when fully loaded.
This distance serves two purposes:
A. It keeps the top layer of milk completely refrigerated even
when the lids are removed.
B. It insures that the lids will operate without striking the
contents as successive layers are added.
Loading: NDF Series
These cabinets are designed to dispense 13” x 13” x 11” high
(maximum dimensions) dairy cases. They do not have a selfleveling mechanism. Simply place the cases on top of each
other inside the cabinet through the wide opening in the top
and front.
Loading: NLFAC Series
These cabinets are designed to dispense 13” x 13” x 11” high
(maximum dimensions) dairy cases. Model NLFAC-8 holds
eight cases; four on the bottom and four on the top. Model
NLFAC-12 holds twelve cases; six on the bottom and six on
the top. Model NLFAC-16 holds sixteen cases, eight on the
bottom and eight on the top.
Milk cases are loaded through the wide opening in the top and
front of the unit. Fold the hinged lids up and back and rest
them on the top. The cabinet interior has self-locating guides
installed to make loading easy.
Operation: FFSC, RFFSC, SCF & NSCF series
FFSC and SCF Series ice cream dispensers are set at the
factory to maintain temperatures between -5°F and 0°F. RFFSC
and NSCF Series combination milk and ice cream dispensers
are set at the factory to maintain temperatures between 36°F
and 40°F for refrigerated product and between -5°F and 0°F for
frozen product. Each combination unit is constructed with two
tanks and separate controls. No further adjustments should be
necessary. To begin operation plug the electrical supply cord
into a receptacle with the correct voltage.
Loading
To load, place two layers of ice cream on the load tray, then a
tray, two additional layers of ice cream, then another tray, etc.
Do not stack ice cream above the frost line on the interior of
the freezer. See the instructions for the MF units (above) for
loading the refrigerated portion of the combination units.
Temperature Control
NLFAC Thermostat Control
Set the thermostat toward 1 for
higher temperatures and toward
7 for lower temperatures. The
refrigerator factory setting is 4
and maintains 38ºF (3ºC) in the
box.
If it is necessary to adjust the temperature, turn the knob
clockwise as indicated on the control. Make adjustments
gradually. It may take an hour to realize the temperature
change. Milk or beverage dispenser factory settings are 17ºF
differential, 34ºF cut in, and 17ºF cut out. Milk and ice cream
dispenser factory settings are 25ºF differential, 30ºF cut in, and
5ºF cut out.
