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.

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 figure 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 figure 2). Lay housing on flat surface.

5. Use Phillips head screw driver to remove front panel on the elevator housing (see figure

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 figure 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.

When adjusting the elevators make sure each have the

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.

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.

For customer service, call (800) 733-8829, (800) 773-8821, Fax (989) 773-3210, www.delﬁeld.com

Low Pressure Control, Remaining Self Contained Models

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.
