or disconnecting the cable connections.
MAINTENANCE CHART
For optimum performance from your dryer, follow the
periodic maintenance schedule described below.
Table 5: Maintenance Chart
WEEKLY
CONDENSATE DRAINS (TIMED AND NO-

Verify that the condensate drains are
operating correctly by pressing the TEST
button.
EVERY 4
MONTHS
CONDENSER
Remove any dust from the condenser
fins.
EVERY 6
MONTHS
AIR FILTER
Replace air filter element.
YEARLY
(TIMED DRAINS ONLY)
Completely disassemble the drains and
clean all their components.
CLEANING CONDENSATE DRAINS (TIMED DRAINS
ONLY)
Periodically clean the screen inside the valve to keep the drain
functioning at maximum capacity. To do this, perform the
following steps:
1. Close the strainer ball valve completely to isolate it
from the air receiver tank.
2. Press the TEST button on the timer to vent the
pressure remaining in the valve. Repeat until all
pressure is removed.
WARNING
High pressure air can cause injury from flying debris.
Ensure the strainer ball valve is completely closed and
pressure is released from the valve prior to cleaning.
3. Remove the plug from the strainer with a suitable
wrench. If you hear air escaping from the cleaning
port, STOP IMMEDIATELY and repeat steps 1 and 2.
4. Remove the stainless steel filter screen and clean it.
Remove any debris that may be in the strainer body
before replacing the filter screen.
5. Replace plug and tighten with wrench.
6. When putting the valve back into service, press the
TEST button to confirm proper function.
TESTING CONDENSATE DRAINS (NO-LOSS DRAINS
ONLY)
