Perlick F24S F24N Operation Instructions - Single Door Freezer, Defrost System - Hot Gas Defrost

Operation Instructions – Single Door Freezer

For sanitation purposes, it may be necessary to seal the base of the cabinet to the floor. This can be accomplished by laying a bead of silicone sealant between the base of the cabinet and the floor as shown by the figure below.

When sealing the cabinet to the floor, make sure that the louvered front grille plate can still be removed for condenser maintenence and cleaning

Defrost System - Hot Gas Defrost

This system consists of a six-hour, as well as a four hour cycle which includes a 20 minute evaporator defrost. The six hour defrost cycle is manually

activated and automatically terminated, while the four hour cycle is completely automatic.

The Six Hour Solid-State Defrost Timer

This timer shuts off the power to the condensing unit, the evaporator fan, and the automatic four hour defrost timer.

To activate the six hour defrost system, depress the defrost switch located on the front grille of the cabinet. An amber light will illuminate and the defrost cycle will begin. When the defrost cycle ends, the light goes off and the cabinet resumes normal operation. To manually cancel the defrost cycle, momentarily turn off the electricity to the machine.

The Four Hour Defrost Timer

This timer ensures that frost will not buildup on the evaporator coil. Every four hours the hot gas by-pass valve is opened and hot gas is circulated through the evaporator coil. The defrost is termin- ated when the coil is clear of frost. The defrost cycle lasts for approximately 20 minutes.

During normal operation it is recommended that the doors are not left open to prevent excessive frost buildup on the coil.

Temperature Control

An adjustable temperature control is located inside the froster on the evaporator fan panel assembly. Approximate temperature operating range: minus 15° F. minimum and plus 10° F. maximum. Make adjustments as shown to attain the desired temperature.

■Colder Temperatures: Turn the adjusting screw clockwise (to the right).

■Warmer Temperatures: Turn the adjusting screw counterclockwise (to the left).

■Temperature Control “OFF”: Turn the adjusting screw completely counterclock- wise to the “O” position until a click is noted.

The condenser fan and the evaporator fan motor turns off and on with the compressor.
