Chapter 5: Maintenance

5-1 Lubrication

Grease all fan motors, and pump motors that do not have permanently sealed bearings. Be sure to use an all-purpose industrial grease with a temperature reference of 185˚ F (85˚ C). Remove the grease relief plug (motors only) before adding grease, add grease until a small amount pours out, and replace the plug when finished.

Caution! Failure to remove the grease relief plug will result in dislodging the bearing grease seal, eventually causing bearing failure.

Refrigeration compressors are hermetically sealed and no lubrication is required.

5-2 Filter Cleaning

Air filter cleaning is important to keep your air-cooled portable chiller operating at peak efficiency and capacity. Clean the filters whenever they appear dirty, or at regularly scheduled intervals.

1.Turn the chiller off.

2.Slide the filter rod to release it from the frame at the top and bottom.

3.Wash down the filter with clean water (preferably with a garden hose), directing the flow of water opposite the direction of airflow. If dirt is heavy, use a mild detergent and rinse well. Allow the filter to dry completely before replacing it on the chiller.

Note: Keep a spare air filter set on hand. Install and use it while cleaning).

Caution! Do not use compressed air to blow off a dirty filter. It will not clean very well, and the filter could be damaged. Never run the chiller without properly installed filters.

5-3 Maintaining the Condenser

Dirty condenser heat exchange surfaces reduce system capacity and efficiency.

Air- and Remote Air-Cooled Chillers

Brush or vacuum light dirt accumulations off the aluminum condenser fins. Avoid bending or damaging them. Heavy dirt accumulations on the fins may require professional cleaning.

Water-Cooled Chillers

Proper water treatment will greatly reduce cleaning intervals.

Coaxial Condensers (5-15 tons). Remove dirt and slime in the condenser tube water side by reverse-circulating with a mild detergent and water solution. Remove mineral deposits by reverse circulating Liquid Inhibited Acid De-Scaling Solution (Part No. A0502600) through the water side of the condenser. Follow the directions on the container.

Shell & Tube Condensers (20-60 tons). Remove dirt and slime in the condenser tube water side by cleaning with a nylon tube brush. Remove mineral deposits by reverse circulating Liquid Inhibited Acid De-Scaling Solution (Part No. A0502600) through the tube water side of the condenser. Follow the directions on the container.

The refrigerant side is sealed and requires no routine maintenance.
