Grease all blower bearings, fan and blower motors, and pump motors that do not have 
permanently sealed bearings. Remove the grease relief plug (motors only) before adding 
grease, add grease until a small amount pours out, and replace the plug when finished. 

Refrigeration compressors are hermetically sealed and no lubrication is required. 

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 up off of the retaining pins holding it in place along its bottom.  

3.  Tip the bottom of the filter away from the chiller.  

4.  Slide it down and out. 

5.  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.
