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 and tested in the Nor-Lake Manufacturing Facility 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 legs or casters found in the interior of the cabinet. Note: Legs or casters are optional on these units. Attach the legs or 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 legs or casters are screwed completely into the base or damage to the base may occur.

If the doors are out of alignment on the cabinet, the doors can be adjusted. Opening the door(s) and loosening the screws that hold both the top and bottom hinges to the cabinet can accomplish this. After adjusting the door so that it is aligned correctly, tighten the screws to securely hold the hinges in place.

LOCATION

The refrigeration system located at the bottom of the cabinet requires free air access for proper operation. In order to assure proper airflow, make certain the flow of air through the front louver panel and the condensing section is not blocked. If the cabinet is on legs, or sits directly on the floor, it should be leveled when it is placed in its permanent location. If the optional legs or casters are not used, it is required by NSF that the cabinet be sealed to the floor by applying silicone around the base of the cabinet. This can be accomplished by using 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 run power to the unit. On permanently connected units, those not furnished with a plug-in service cord, 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 the Electrical Data below and the Serial Tag for all pertinent electrical information.

Observe all Warning Labels. Disconnect power supply to eliminate electrical shock and injury from moving parts when servicing equipment.

GENERAL OPERATION

The Ice Cream Topping Refrigerator or Freezer employs a forced air evaporator located inside the cabinet as the heat-removing source. Through the refrigeration process, heat is captured in the unit cooler, transferred to the condensing unit at the bottom of the cabinet, and expelled to the surrounding outside air. In order to assure proper operation, make certain the flow of air through the front louver panel and the condensing section is not blocked.

REFRIGERATORS

The automatic air defrost refrigerator employs a fin-and-tube evaporator with a fan motor as the cold producing apparatus. During the operation of these units, frost will periodically form on the coil surface. Each time the condensing unit cycles to the off position, the evaporator fans will continue to run, which will tend to keep the internal temperature at a constant and at the same time remove any frost build-up on the coil. The water produced will collect in the unit cooler drain pan and travel down the drain tube to the condensate vaporizer.
