Operation - GeneralAll the chest freezer models are of the same basicdesign consisting of a hot wall condenser cap tube fedtank wrap evaporator. Ice formation on the walls over aperiod of time is normal. This frost should be scraped offperiodically in order to maintain peak performance.These cabinets are thermostatically controlled for vari-ous temperature requirements. The thermostat islocated post adjacent to the unit compartment and canbe accessed for adjustment by the user with a screw-driver or a dime. Thermostat position #1 being thewarmest and position #7 being the coldest.These cabinets are manual defrost and a drain is pro-vided for periodic cleaning. A garden hose can beattached to the drain plug for draining any water thatmay accumulate. This drain attachment is located in thefront base rail of the cabinet.NOTE: The power supply cord must be disconnectedwhen cleaning or servicing these cabinets.On initial cabinet pulldown, the hot wall condenser maybecome warm to the touch until the normal operatingtemperatures are achieved.Refer top model serial data tag for cabinet amperage,refrigerant charges and type.CABINET CONSTRUCTIONThe low side tank is lowered into the outer shell andanchored to the sub top by a plastic extrusion and foam.The space between the outer wrapper and the innertank 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 ofthe low side can be made.The stainless steel top capping is of drawn one piececonstruction. It is put in place after the inner tank isassembled to the wrapper and is secured to the sides ofthe cabinet with 1⁄8" pop rivets.COOLING TANK ASSEMBLYThe low side assemblies are designed so that the sidesand the ends of the tank are refrigerated.The evaporator coil assembly on the tank is different tothat on previous models. It is now a serpentine coilarrangement. The new evaporator starts at the top of theinner tank and spirals downward to the condensing unit.The thermostat bulb well is located near the front of themachine compartment in all models.CHAMBER GUARDSThe one-piece vinyl chamber guard extends from thetop of the lid opening down into the inner tank.Galvanized steel chamber guard retainers mounted inthe top of the tank frame hold the vinyl chamber guardagainst the top stainless steel capping. A special sealingcompound laid on the inside angle of the retainers sealsthe vinyl to the stainless steel capping. One-pieceretainer brackets along the lower edge of the tank frameretain the lower edge of the vinyl chamber guard.To remove the vinyl chamber guard, merely unhookfrom lower edge of the brackets and the top edge of thechamber guard retainers.
