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 and/or result in injury to the operator and/or bystanders.
Important information is contained in these instructions which should be retained in a convenient location for future reference.

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 for 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.

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
Do not, under any circumstances cut or remove the round grounding prong from the appliance plug.
WARNING
Consult a licensed electrician if you have any doubt about the grounding of your wall receptacle. Only a licensed electrician can determine the polarization of your wall receptacle. Only a properly installed threeprong wall receptacle assures the proper polarization with the appliance plug.

Cleaning Instructions
DIRECTIONS FOR PROPER CARE & CLEANING
1.Wipe up spilled foods promptly.
2.Use lukewarm detergent solution for cleaning the cabinet interior, exterior, and lids. Follow with a clean, damp cloth and then wipe dry.
3.Protect the exterior enamel finish and plastic lid frame with automotive type cleaner and wax.
4.Protect all stainless steel surfaces with a commercial silicone emulsion type cleaner. This cleaner is excellent for all stainless steel surfaces. It leaves a protecting film that prevents fingermarking and the adherence of food particles.
5.CAUTION:
a.Never use naptha or solvent type cleaner on plastic parts or lid frames.
b.Never use 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 cabinet 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 interior. (See Item 2 above.)
INSTRUCTIONS FOR SEALING CABINET TO FLOOR
The National Sanitation Foundation recommends these cabinets be sealed to the floor to prevent water, 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.

DRAIN IN LINER
DRAIN CAP
A drain fitting is located in the bottom of the storage tank. To drain the defrost water:
1.Remove and store products in another freezer.
2.Loosen and remove any items such as ice cream, nuts, berries, paper labels, etc., which could plug the bottom drain.
3.Remove the cap from the drain hose fitting.
4.Connect a hose to the fitting and run it to a floor drain, a shallow (2" high maximum) pan, or to a “Filordrain” at the sink.
5.Disconnect the cabinet by pulling the plug or turning the thermostat off to melt down the frost.You can hasten the defrost by using the “Filordrain” or a hose to spray warm water on the cabinet walls. (Detailed instructions for using the “Filordrain” for spraying the frost and removing the accumulated water are available from your dealer.)
6.Recap hose fitting after defrosting is complete.

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 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 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 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)
