Note: Disconnect power prior to installation.
1. Connect the power cord to the vaporizer and place it in
the vaporizer bracket.
2. Attach the vaporizer bracket to the back of the unit using
the four screws as shown, making sure the plastic drain
tube is in the vaporizer pan.
LOCATION
The refrigeration system located at the top of the cabinet
requires free air access for proper operation. Allow a minimum
four (4) inch clearance on the top, rear, and sides of the
cabinet. The cabinet should also be levelled when it is placed
in its permanent location. There are no provisions for easily levelling the Roll-In models except
by the use of shims. Only minimal shimming is allowable. A cabinet that will sit directly on the
floor without casters should be levelled when placed in its permanent location. If casters are
not used,
it is required by NSF that the cabinet be sealed to the floor with an approved sealant
such as Dow Corning #732 silicone.
ELECTRICAL
Check the proposed outlet to be used to insure that the voltage, phase and current carrying
capacity of the circuit from the electrical panel correspond to the requirements of the cabinet.
NEVER use an extension cord to wire any unit. On permanently connected units, those not
furnished with a plug-in service cord, all inter-wiring between the electrical panel and the unit
must be done in accordance with the National Electric Code and all state and local codes.
Refer to the serial tag for all pertinent electrical information.
Observe all Warning Labels. Disconnect power supply to eliminate injury from
electrical shock or moving parts when servicing equipment.
GENERAL OPERATION
The refrigerators and freezers employ a unit cooler evaporator located outside the cabinet as
the heat removing source. Through the refrigeration process, heat is captured in the
evaporator, transferred to the condensing unit on top of the cabinet, and expelled to the
surrounding outside air. It is extremely important to allow a four (4) inch clearance on the top,
rear, and sides of the unit for the refrigeration process to function properly.
These refrigerators and freezers utilize a programmable controller to control the
temperature and defrost settings. The controller, which is located on the facade of the
unit, is factory set. Please see the default settings sheet and separate instructions that
are included on the operation of this controller.
