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 this unit. 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 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.
The Milk Storage unit employs a unit cooler evaporator located inside 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 inch clearance between the back of the unit and a wall for the
refrigeration process to function properly.
During the operation of this cabinet, frost will periodically form on the 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 unit cooler drain pan and travel down the drain tube to a floor drain or
the optional condensate vaporizer.

PERIODIC CLEANING

Beginning with the initial installation, the interior surfaces of the cabinet should be periodically wiped
down with a solution of warm water and baking soda. This solution will remove any odors from
spillage that has occurred. The exterior of the cabinet should also be cleaned frequently with a
commercial grade glass cleaner or with mild soap and water. Never, under any circumstances, use
an abrasive cleaner or alkaline solution.
Monthly cleaning of the condenser will aid the heat transfer characteristics of the refrigeration
system and increase its efficiency. Dust, dirt, and lint will tend to accumulate on the fins of the
condensing unit. This obstruction will affect the flow of air through the condenser, thereby lowering
the efficiency of the system. A wire brush or a brush with stiff bristles can be used to loosen these
particles that are attached to the fins so that they may be removed with a vacuum cleaner. Failure
to keep the condenser coil clean and clear of obstructions could result in temperature loss
and damage to the compressor.
All moving parts have been permanently lubricated and will generally require no maintenance.
