Maintenance
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. To accomplish this, remove the louvered panel from the cabinet and use a wire brush
to loosen any dirt particles that are attached to the fins. After this is accomplished, use a vacuum cleaner to
remove the loosened particles.
Operation
The milk coolers are cooled entirely by convection as a result of copper coils completely encircling the
perimeter of the storage compartment. 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 uses a temperature thermostat that senses the cut-in and cut-out temperatures of the
cold wall evaporator coil. The temperature can be adjusted by turning the thermostat control knob which is
located behind the louvered side panel.
Installation
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. Plug all standard models into
a 110 volts A.C.60 cycle outlet. NEVER use an extension cord to power any 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 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.
