WARNING
The Series AFR Air Filter Regulator is intended for use in industrial
compressed air systems only. Do not use these products where
pressures and temperatures can exceed those listed under
specifications.
Before using these products with fluids other than air, for non-industrial
applications, life-support systems, or other applications not within
published specifications, contact Dwyer Instruments, Inc.
MAINTENANCE
To Remove Condensate
Slowly open drain valve and bleed accumulated liquid.
To Clean Filter Element
1) Shut off air supply.
2) Drain condensate.
3) Remove four corner bolts from bottom of unit.
4) Remove dripwell housing and filter.
5) Clean parts and reassemble in reverse order.
