Operation - General
All the chest freezer models are of the same basic
design consisting of a hot wall condenser cap tube fed
tank wrap evaporator. Ice formation on the walls over a
period of time is normal. This frost should be scraped off
periodically in order to maintain peak performance.
These cabinets are thermostatically controlled for vari-
ous temperature requirements. The thermostat is
located post adjacent to the unit compartment and can
be accessed for adjustment by the user with a screw-
driver or a dime. Thermostat position #1 being the
warmest and position #7 being the coldest.
These cabinets are manual defrost and a drain is pro-
vided for periodic cleaning. A garden hose can be
attached to the drain plug for draining any water that
may accumulate. This drain attachment is located in the
front base rail of the cabinet.
NOTE: The power supply cord must be disconnected
when cleaning or servicing these cabinets.
On initial cabinet pulldown, the hot wall condenser may
become warm to the touch until the normal operating
temperatures are achieved.
Refer top model serial data tag for cabinet amperage,
refrigerant charges and type.
CABINET CONSTRUCTION
The low side tank is lowered into the outer shell and
anchored to the sub top by a plastic extrusion and foam.
The space between the outer wrapper and the inner
tank is then filled with urethane foam insulation (2-

thick) forming a three-ply wall of single unit construction.
The low side tank then is not removable and no repair of
the low side can be made.
The stainless steel top capping is of drawn one piece
construction. It is put in place after the inner tank is
assembled to the wrapper and is secured to the sides of
the cabinet with

COOLING TANK ASSEMBLY
The low side assemblies are designed so that the sides
and the ends of the tank are refrigerated.
The evaporator coil assembly on the tank is different to
that on previous models. It is now a serpentine coil
arrangement. The new evaporator starts at the top of the
inner tank and spirals downward to the condensing unit.
The thermostat bulb well is located near the front of the
machine compartment in all models.
CHAMBER GUARDS
The one-piece vinyl chamber guard extends from the
top of the lid opening down into the inner tank.
Galvanized steel chamber guard retainers mounted in
the top of the tank frame hold the vinyl chamber guard
against the top stainless steel capping. A special sealing
compound laid on the inside angle of the retainers seals
the vinyl to the stainless steel capping. One-piece
retainer brackets along the lower edge of the tank frame
retain the lower edge of the vinyl chamber guard.
To remove the vinyl chamber guard, merely unhook
from lower edge of the brackets and the top edge of the
chamber guard retainers. (See below)
