Cleaning with Compressed Air

Blow clean, dry compressed air up and down the pleats, blowing out the filter from the inside out. Remove loose dirt from the filter with compressed air or vaccum from the outside.

Caution! DO NOT clean/wash filter with water!

After each cleaning:

•Inspect the filter element. Briefly hold a light bulb behind the element and look for any fatigued paper or residual dirt. Inspect for holes and tears by looking though the filter toward a bright light. Check for damaged gaskets or dented metal parts. Do not re-use a damaged filter!

•Check the gasket for damage. A damaged gasket allows contaminants into the process. Replace as needed.

Use compressed air or a steam cleaner to blow the dust off or clean any oily residue on the coil.

Note: To clean the cooling coil, use compressed air or a steam cleaner to blow the dust off or clean any oily residue on the coil.

Servicing the Dew Point Monitor

The accuracy of the dew point monitor on mini dryer systems depends on proper operation of the dew point sensor and the control board. The dew point sensor is in the process air stream and is therefore susceptible to contamination.
