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 power any unit. All 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 Electrical Data below and 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 milk coolers are cooled entirely by forced air evaporator. During the refrigeration process, heat
is removed through the evaporator tubing and expelled through the condensing unit. It is important
that the flow of air through the side louvers is not restricted in order to ensure the condensing unit
operates properly. Under normal operating conditions, any frost that might accumulate on the walls
during the "on" cycle of the condensing unit may melt during the "off" cycle. Drains are installed in
all milk coolers to accommodate melting frost.
The refrigeration system on this cabinet utilizes a programmable temperature controller to
control the temperature and defrost settings. The controller, which is located in the
condensing unit enclosure, is factory set. Please see the default settings sheet and separate
instructions that are included on the operation of this controller.
During the operation of the refrigeration unit, frost will periodically form on the evaporator coil
surface. Each time the compressor cycles “off”, the evaporator fans will continue to run, which will
keep the internal temperature uniform and, at the same time, remove any frost build up on the coil.
The water produced will collect in the condensing unit drain pan and evaporate.
