Installation, Operation and

Maintenance Instructions

INSPECTION

When the equipment is received, all items should be carefully checked against the bill of
lading to insure all crates and cartons have been received. All units should be inspected
for concealed damage by uncrating the units immediately. If any damage is found, it
should be reported to the carrier at once, and a claim should be filed with the carrier. This
equipment has been inspected, tested and has been crated in accordance with
transportation rules and guidelines. Manufacturer is not responsible for freight loss or
damage.

INSTALLATION

GENERAL

After the unit crate and base have been removed, locate the casters found in the interior of
the cabinet. Attach the casters to the unit base by screwing them into the same threaded
fittings that were used to secure the crate base to the cabinet. Insure that the casters are
screwed all the way into the base.

LOCATION

The self contained refrigeration system located at the bottom of the cabinet requires free air
access for proper operation. The back of the cabinet may be positioned against a wall,
however, there must be a minimum four inch clearance between the sides and a wall.
These guidelines must be followed for cabinets with or without casters. A cabinet that will
sit directly on the floor without casters should be leveled when it is 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 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 Table 2 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 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 cut­in 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.
