Auto Drain Maintenance
Remove the dust accumulated in the auto drain every month. Use neutral detergent for cleaning.
When cleaning does not improve the operation, replace the element and bowl assembly. From the next
time on, clean them in intervals shorter than a month.
(1) Follow the procedure below for the auto drain maintenance.
1) Turn on the stop switch of the product and stop the operation.
2) Shut off the power supply from the earth leakage breaker.
3) Fully close the valve at the compressed air IN and OUT piping. (Open the bypass valve, only when
compressed air is required during maintenance.)
4) Remove the exterior panel where it is necessary for the work.
Wear protective goggles or mask during air blow.
CAUTION
- Be sure to release the residual pressure of the auto drain before starting maintenance.
- When the bowl assembly is broken or very dirty, replace it with a new one.
