2. Where codes permit, we recommend that the freezer be installed on casters and have flexible water and electrical connections for service and cleaning ability.

3. Air cooled models require a minimum 6 inch (15 cm) clearance on either the side panels or the rear panel for adequate ventilation. Freezers designed with top air discharge require that at least 18 inches (45 cm) above the top panel be free of obstructions. Anything blocking ventilation of the freezer (including cone dispensers) will reduce the efficiency of the freezer.

4. Water cooled models will require a 1/2 inch MPT water inlet and

CAUTION To prevent accidental electrical shock, a positive earth ground is required.

1. Always verify electrical specifications on the data plate of each freezer. Data plate specifications will always supersede the information in this manual.

CAUTION To prevent accidental electrical shock, a positive earth ground is required.

1. Double freezers with two compressors require one power supply for each side of the freezer. Each side of the freezer operates independently.

2. Check the data plate for fuse size, wire ampacity and electrical specifications.

water waste connection. Both condensers are tied together so that one water inlet and one water waste is all that is required. The connections are found on the bottom under the compressor mounting area and are tagged “Water Inlet” and “Water Waste.” A manual shut-off valve should be installed in the water inlet line at the time of installation. The water pressure must be between 35-140 psig (241-965 kPa) for proper operation.

5. Place the freezer in the final location and level by adjusting the legs or casters so that it is level side-to-side and the front is approximately ¼ inch lower than the rear (to allow proper drainage of the freezing cylinder).

2. Supply voltage must be within + 10% of voltage indicated on the nameplate. Also, on three-phase systems, voltage between phases must be balanced within 2%. (More than a 6 volt difference between any two voltage measurements at 208-230 volts indicates a possible imbalance.) Request your local power company to correct any voltage problem.

3. An easily accessible main power disconnect must be provided for all poles of the wiring to the freezer.

3. Refer to the wiring diagram

provided for proper power connections.

4. Electrical connections are made in the junction box located mid-level behind the left side panel.

5. Use a flexible connection when permissible. All materials and connections must conform to local codes and the National Electrical Code.

6. For 3 phase freezers, beater shaft rotation must be clockwise as viewed from the front of the freezer.

5 Operator Controls and Indicators

Figure 5-1

The following paragraphs describe the operator controls and indicators. Refer to figure 5-1 for location of these controls and indicators on the freezer.

NOTE: The head must be in place before the beater will operate.

This three-position switch controls the operating mode of your freezer.

a. “CLEAN” (left) — This position operates the beater only (no refrigeration to the cylinder). Always use this mode when performing cleaning and sanitizing operations.

b. “OFF” (center) — In this position the beater motor will not operate and no refrigeration will be provided to the cylinder.

CAUTION Test operation of the head switch prior to placing the freezer in service. See Section 11, Routine Maintenance, Monthly.

 Important: Do not use the “AUTO” position with water or sanitizer in the cylinder — the freezer will be damaged.

c. “AUTO” (right) — This position activates both the beater motor and refrigeration unit. This is the normal operating position.

23456789012345

This two-position switch controls the day and night refrigeration modes.

a. “DAY” (left) — The low temperature thermostat controls the system refrigeration to maintain the product serving temperature between 18° to 21°F (-8° to -6°C). This is the normal operating position.

This two-position switch controls the operation of the MTS located in the refrigerated mix storage cabinet.

a. “ON” (left) — This position is the

normal operating mode. Use this position for priming the cylinder, cleaning and day mode operation.

This two-position switch controls the cabinet refrigeration.

NOTE: Cabinet door must be closed for cabinet refrigeration to operate.

a. “ON” (left) — The cabinet thermostat controls the system refrigeration to maintain a mix temperature of 36 to 41°F (2 to 5°C) in the storage cabinet. Always use this position when mix is in the storage cabinet but not in the cylin-

 Important: If the overload trips frequently, your freezer should be checked for proper product temperature, overrun and voltage. Contact your Electro Freeze Distributor.

b. “NIGHT” (right) — The medium temperature thermostat controls the system refrigeration to maintain a mix holding temperature of 41°F (5ºC) or below.

b. “OFF” (right) — In this position the MTS will not operate. Use this position for night mode operation.

der.

b. “OFF” (right) — The cabinet will not be refrigerated if the SELECTOR switch is also in the “OFF” position.

NOTE: The cabinet is automatically “ON” when either SELECTOR switch is in the “AUTO” position.

This control protects the beater motor against failure from an overload condition by automatically shutting down the freezer. To restart properly, turn the SELECTOR switch to “OFF”, wait 2-3 minutes. Then depress the red reset button and turn the SELECTOR switch back to the “AUTO” or “CLEAN” position.

Safety Information

This freezer uses pressure to assure consistent product quality. It is important for your safety that the freezer is depressurized slowly and completely whenever the freezer is to be drained, disassembled, cleaned, or serviced. The safety instructions in this manual will remind you when to check to make sure the freezer is depressurized. When you see this CAUTION statement

CAUTION Make sure freezer is depressurized before proceeding.

the following steps should be taken:

1. Make sure both MTS switches and both selector switches are in the “OFF” position.

2. Place a clean bucket under the dispense head.

3. Slowly open the plungers by pulling down on each of the dispense handles, allowing any pressurized product, cleaning solution, or air to escape. If there is product in the freezer refer to Section 9, Closing Procedures, 9.2 Draining Product.

4. Remove the plunger rods and open the plungers completely.

CAUTION To avoid electrical shock or contact with moving parts, make sure all switches are in the “OFF” position and that the main power supply is disconnected. Some freezers have more than one disconnect switch.

5. Inside the refrigerated cabinet, remove the MTS cover, loosen the shoe clamp hand knob, swing back the shoe clamp and swing open the roller shoe on both mix transfer systems.

Following these steps will assure that the system is depressurized.

It is important that the freezer be disassembled, washed, lubricated and sanitized before operation.

The cleaning and sanitizing instructions explained in this manual are required to maintain a clean, sanitary freezer. The freezer should be disassembled, cleaned, reassembled, lubricated and sanitized daily to ensure the best possible product quality and freezer operation.

Persons assembling, cleaning or sanitizing the freezer must first wash and sanitize hands and forearms with an approved sanitizer.
