MAINTENANCE

The dryers require little maintenance for satisfactory 

operation. Good dryer performance can be expected if 

the following routine maintenance steps are taken.

Daily Maintenance

Check the separator for condensate discharge. If no 

discharge is evident, depressurize and dismantle.  Clean 

separator housing with mild soap and water. Discard 

automatic float drain and replace.

Monthly Maintenance

Inspect the condenser coils. Remove accumulated dust 

and dirt with a soft brush or with air from an OSHA 

approved compressed air nozzle that limits the discharge 

pressure to 30 psig.

General

For continued good performance of your refrigerated 

dryer, all refrigeration system maintenance should be 

performed by a competent refrigeration mechanic.

NOTE:

 Before corrective maintenance is done during the 

warranty period, call your local distributor and proceed 

according to instructions. Refer to the warranty for limits 

of your coverage.
