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

Legs or casters are optional with these units. If ordered, and after the crate and crate base have

been removed, locate the casters or legs found in the interior of the cabinet. Attach the casters or legs to the unit by screwing them into the support gussets that are secured to the base of the cabinet. Ensure that the casters or legs are screwed all the way into the gussets.

LOCATION

The cabinets should be leveled as they are installed on a firm, permanent floor, or base. Make certain that all four corners of the cabinet are in contact with the floor. Doing this will ensure satisfactory operation of the doors and gasket seal, and allow for minimum condensing unit noise with the self contained units (cabinets with condensing units attached). Also, with self-contained units, there must be a minimum four-inch clearance between the rear of the cabinet and the wall for air access. This is required for proper operation of the refrigeration system. Once the cabinet is leveled, it is required by NSF that the cabinet be sealed to the floor with an approved sealant such as Dow Corning #732 silicone.

Many installations require that the condensing unit be located in a remote location instead of attached to the cabinet. Like the self-contained units, it is necessary to mount the condensing unit on a substantial base near a power source. In all remote installations, the blower coil must be wired for continuous operation even though the compressor runs intermittently. If a temperature control is used to maintain proper interior temperatures, make certain that the wire from the control of the condensing unit is no lighter in gauge than the power cord in order to avoid a voltage drop at the compressor. When a pressure control is used, as is in most cases, the control itself will normally be located at the condensing unit.

ELECTRICAL

Check the proposed outlet to be used to ensure 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 power any unit. 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 Electrical Data and the Serial Tag for all pertinent electrical information.

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

GENERAL OPERATION

The Back Bar and Direct Draw refrigerators employ a unit cooler evaporator located inside the cabinet as the heat-removing source. Through the refrigeration process, heat is captured in the evaporator, transferred to the condensing unit, and expelled to the surrounding outside air. With the self contained units, it is extremely important to maintain the minimum four-inch clearance between the rear of the cabinet and the wall for the unit to function properly.

During the operation of these units, frost will periodically form on the coil surface. Each time the refrigeration compressor cycles to the "off" position, the evaporator fans and condenser fans will continue to run. This will tend to keep the interior of the cabinet at a constant temperature and at the same time remove any frost build up on the unit by circulating the inside air over the coil. The water produced will collect in the unit cooler drain pan and travel down a drain tube to vaporize back into the air.
