7.4 Condensate Removal
The non-cycling refrigerated air dryer uses a refrigeration
circuit to cool the compressed air which causes moisture to
condense. The condensed moisture is separated from the dry
air and purged through an automatic drain.
1. Condensate downstream of dryer:
•
If the unit is equipped with automatic drain override
switch, push manual override button to test drain flow.
•
Ensure automatic electronic timer (if applicable) is
functioning properly.
•
Ensure moisture separator (and coalescer) drain lines are
free from blockage.
•
If the unit is equipped with y-strainer, disassemble and
clean.
•
If oil is downstream from the dryer:
•
Oil coalescer element is saturated.
•
Dryer not turned on during air usage.
