This freezer is designed to produce shakes with a product serving temperature of 27° to 30°F (-3 to-1°C).

This manual has been prepared to assist you in the proper operation and

general maintenance of the Electro Freeze Model 78RMT.

Your freezer will not compensate for or correct any assembly or priming errors made during the initial start-up. Therefore, it is extremely important to follow the assembly and priming procedures detailed in this manual.

Make sure all personnel responsible for equipment operation completely read and understand this manual before operating the freezer. When properly operated and maintained, the freezer will produce a consistent quality product.

This freezer must be installed and serviced by an Electro Freeze Distributor or authorized service technician in accordance with the installation instructions.

After installation the warranty registration card must be completed and returned to validate the warranty.

2.1 Uncrating and Inspection

2345678901234

When the unit is received and while the carrier is still present, inspect the shipping carton for any damage that may have occurred in transit. If the SHOCKWATCH® label indicates red and/or the carton is broken, torn, or

Figure 2-1 Freezer Bolted to Shipping Base

FRONT

Figure 2-2 Installing Mounting Legs or Casters

CAUTION Be sure to properly support the machine when removing bolts and installing legs or casters.

punctured note the damage on the carrier’s freight bill and notify the carrier’s local agent immediately.

1. Remove the carton from the pallet, and move the freezer as close as possible to the permanent location.

2. Remove the shipping bolts on the bottom of the freezer (figure 2-1) and install either the legs or casters (figure 2-2).

NOTE: Screw casters or legs all the way in coupling, then adjust out to level side to side with a 1/4” slope to the front.

2.3 Electrical Requirements

2345678901234

2.4 Electrical Connections

2345678901234

184956

CAUTION All materials and connections must conform to local requirements and be in compliance with the National Electrical Code (NEC).

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

2. ALL models require a minimum

6-inch (15cm) clearance on either the side panels or the rear panel for adequate ventilation. Freezers designed with top air discharge require that the top panel be free of obstructions. Anything blocking ventilation of the freezer (including cone dispensers) will reduce the efficiency of the freezer.

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. See Figure 3-1.

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

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

2. Refer to the wiring diagram provided for proper power connections.

3. Water cooled, models require a

3/8-inch MPT water inlet and water waste connection. The connections are found on the bottom, under the compressor mounting area. They 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 above 35 psig (241 kPa) and below 140 psig (965 kPa) for proper operation.

4. Place the freezer in its final location and adjust the legs or casters so that it is level side-to-side and the front is approximately 1/4-inch lower than the rear to allow proper drainage of the freezing cylinder. To insure proper stability, do not mount cup dispensing racks or unapproved accessories on the freezer.

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

4. Use a flexible connection when permissible. All materials and connections must conform to local codes and/ or the National Electrical Code (NEC).

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