Service Information

All units are designed for maximum durability, reliability and

simplicity. comes to you ready for operation, fully charged and with all controls preset at the factory. The following information is provided as an aid in the event that service is required.

Maintenance

 

The evaporator section of a

 

system should be checked at

 

least once for proper defrosting

because the amount and pattern

 

of frosting can vary greatly. The frost build-up is dependent on

 

the temperature of the room, the type of product being stored,

2.Freezers

how often new product is brought into the room and percentage

of time the door to the room is open. It may be necessary to

periodically change the number of defrost cycles or adjust the

duration of defrost.

System Standard Maintenance Guidelines

After first year of operation and under normal usage, maintenance should cover the following items at least once every six months:

1.Check and tighten ALL electrical connections.

2.Check all wiring and insulators.

3.Check contactors for proper operation and for worn contact points.

4.Check all fan motors. Tighten motor mount bolts/ nuts and tighten fan set screws.

5.Clean the condenser coil surface.

6.Check the operation of the control system. Make certain all safety controls are operating properly.

7.Check that all defrost controls are functioning properly.

8.Clean the evaporator coil surface.

9.Clean the drain pan and check the drain pan and drain line for proper drainage.

Refrigeration Sequence of Operation

1.Power is provided to the temperature control, compressor contactor and cooler evaporator fans.

2.The temperature controller closes and energizes the compressor contactor, starting the compressor, evaporator and condenser fan(s).

3.When the system reaches the desired box temperature, the temperature control will de-energize the compressor contactor. Evaporator fans will continue to operate at this point.

4.When the fixture temperature rises above the set point and minimum off-time has elapsed, the temperature control will close and re-energize the compressor contactor.

Electric Defrost Sequence of Operation for Freezers

1.During normal operation, at the preset time intervals, the temperature/defrost control will de-energize the compressor contactor and evaporator fans and energize the defrost heaters. These functions are controlled through relays on the controller.

2.When the coil has defrosted fully and has reached the preset coil temperature (as sensed by the coil temperature sensor) the defrost heater de-energizes and the fan delay and drip sequences begin.

3.The temperature/defrost control energizes the compressor contactor, starting the compressor and condenser fan(s).

4.Freezer evaporator fans will be energized by the temperature/defrost control when the coil temperature reaches 35°F or fan delay time has elapsed.
