All PRO3 packaged refrigeration system units are designed for maximum durability, reliability and simplicity. The PRO3 packaged refrigeration system 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.

The evaporator section of a PRO3 packaged refrigeration 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, 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.

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 all defrost controls for proper function.

8.Clean the evaporator coil surface.

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

CAUTION: Unit is critically charged, care must be taken not to reduce the system refrigerant charge while taking pressure readings. Technician must compensate for any refrigerant that might escape the unit into the gauge tubing.
