Installation & Operation Instructions
These instructions include information which is intended
to assure the operator of correct installation, operation,
and service. Before attempting installation, adjustment
or maintenance, be certain of the following:
1.That you have read and fully understand the instructions.
2.That you have all the tools required and are trained to
use them.
3.That you have met all installation and usage restrictions and are familiar with the functions and operation
of the unit.
4.That you follow all instructions exactly as given.
All fittings, measurements, procedures and recommendations are significant. Substitutions and approximation
must be avoided. Improper handling, maintenance,
installation and adjustment or service attempted by anyone other than a qualified technician, may void the
future warranty claims and cause damage to the unit

INSTALLATION INSTRUCTIONS
Thermostat will maintain approximately zero degrees on
the original factory setting. Turn the adjusting screw
clockwise for colder and counterclockwise for warmer.
IMPORTANT: Turning control counterclockwise to the
stop shuts cabinet "OFF".
For storage of package ice cream, turn thermostat to
coldest position. Limit top layer of package to a height
consistent with cabinet usage and turn over of product.
LOCATION
Select a location for the cabinet which will be most convenient for the customer and which will allow adequate
air circulation.Restricted air flow will result in higher condensing pressures and operating costs.
Provide at least a 1-inch space around the exterior of
the cabinet. The outside shell is the condenser and
depends on the natural convection of room air for dissipation of its heat. Stainless or formica facing sheets
applied to the cabinet exterior should be in tight contact
with the cabinet's outer walls to improve the heat flow.
When a cabinet is built into a counter or back-bar and
space is allowed between the counter and the cabinet
walls, provide holes or louvers along the top edge f or hot
air to escape.Holes should be screened to keep insects
and rodents out.
IMPORTANT: Before building any piece of equipment
in, run it to be sure the operation is satisfactory.
BE SAFE. SEE ILLUSTRATION ABOVE.
When a cabinet is installed in a moving vehicle, use the
original crate mounting angles or equivalent to securely
bolt the cabinet to the vehicle floor so it won't move
going around corners or during sudden starts and stops.
INSTALLATION & OPERATION 3
Important information is contained in
these instructions which should be
retained in a convenient location for
future reference.
Grounding Instructions
This appliance is equipped with a three-prong (grounding) plug for your protection against shock hazards.The
appliance should be plugged directly into a properly
grounded three-prong receptacle.
Where a two-prong wall receptacle is encountered, it
must be replaced with a properly grounded three-prong
receptacle in accordance with the National Electrical
Code and local codes and ordinances. The work must
be done by a licensed electrician.
IMPORTANT

5. CAUTION:
a. Never use naptha or solvent type cleaner on plas-
tic parts or lid frames.
b. Never u se harsh abrasive polishes on plastic parts
or plastic lid frames.
c. Do not blow steam or dash excessively hot water
against plastic materials when cleaning the tank or
defrosting, as damage to plastic parts may occur.
6.When the cabinet is taken out of service for more than
a short period:
a. Remove lids. (DO NOT replace them on the cabi-
net until the cabinet is again refrigerated.)
b. Defrost cabinet and remove any spilled ice cream
from the chamber guards.
c.Wash and dry chamber guards and cabinet interi-
or.(See Item 2 above.)
INSTRUCTIONS FOR SEALING
CABINET TO FLOOR
The National Sanitation Foundation recommends these
cabinets be sealed to the floor to prevent w ater, dirt and
vermin, etc. from getting under the cabinet. The instructions below meet their requirements.
1. Position and level the cabinet.
2. Draw outline of the base on the floor.
3. Raise and block the front side of the cabinet as illustrated in FIG. 1.
4. Apply a bead of mastic (See approved list below) to
the floor one half inch inside the outline drawn. (See
FIG. 2.) Bead must be heavy enough to compress at
all points when the cabinet is set down.
5. Raise and block the rear of the cabinet as illustrated
in FIG. 1.
6. Apply mastic on the floor as outlined in step 4 on the
other three sides.
7. Examine to see that cabinet is sealed to floor around
entire perimeter.
NOTE. Asphalt floors are very susceptible to chemical
attack. A layer of tape on the floor prior to applying the
mastic will protect the floor.

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 various temperature requirements. The thermostat is
located post adjacent to the unit compartment and can
be accessed for adjustment by the user with a screwdriver or a dime. Thermostat position #1 being the
warmest and position #7 being the coldest.
These cabinets are manual defrost and a drain is provided 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 (2-1⁄4"
thick) forming a three-ply wall of single unit construction.
The low side tank then is not removab le 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 1⁄8" pop rivets.
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 low er 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)
