Clean the condenser coil annually.

Clean the refrigerator’s air filter every 3 months.

Clean the refrigerator interior and exterior periodically.

Inspect the pump tube for wear. Replace it if necessary.

Clean the pump tubing housing.

Change the suction line if necessary.

Clean the bottles, suction line, strainer and pump tube.

Check the humidity indicator.

Check the controller’s internal battery status and replace the battery every five years.

If the keypad label has bubbles under it, the air inside the controller has expanded. To release this pressure, unscrew the flow meter cable or connector cap on the back of the controller. Push down on the label to force the air out, then re-tighten the cable connector or cap.

8.2 Cleaning Guidelines

8.2.1 Refrigerator

The refrigerator’s exterior may be periodically cleaned with

 

soapy water using a sponge or nonmetallic brush to keep it free

 

of corrosive solutions, grease, oil, etc. After cleaning, it should be

 

wiped dry. Automotive wax may be applied to the interior and

 

exterior surfaces to make them easier to clean and more

 

resistant to corrosion. Do not direct a hose spray toward the

 

underside or into the front grill of the refrigerator. The vacuum

 

formed plastic refrigerator interior may also be cleaned with

 

soap and water as necessary.

 

Because the refrigerator uses a forced-air system, dust and

 

debris will collect on the condenser coil and surrounding areas. If

 

the refrigerator is not cleaned periodically, damage due to over-

 

heated components may result.
