base

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. Air cooled models require a minimum 6-inch 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.

Figure 2-2 Install mounting legs

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

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

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 carton is broken, torn, or 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 machine 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).

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.

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.

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

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. Electrical connections are made in the junction box located mid-level

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

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.

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).
