Cleaning Air Filter

Air filter removes foreign matter and condensate from
supply air as it passes through filter. Frequency at
which the filter baffle plate and filter element should
be cleaned depends upon amount of condensate and
foreign matter in supply air. Condensate level should
not rise above baffle. This is the sign of a faulty auto-
drain which would need to be cleaned, replaced or
repaired.

Erratic regulator operation or loss of regulation is
almost always due to dirt.

The following steps outline the procedure for cleaning
air filter.

1. Close and lock air supply line shut-off valve.

2. Remove filter bowl. Use a strap wrench if

required. Disassemble regulator, making notes as
a guide for reassembly.

3. Clean parts with household soap (Dawn™,

Ivory™, etc.) and blow out body with
compressed air.

NOTE: DO NOT use cleansing agents such as
acetone, benzene, carbon tetrachloride, gasoline, or
toluene, which are damaging to plastic sight glass.

4. Reassemble per notes from step 2. Ensure o-ring

is in position on filter bowl. Tighten bowl to filter
body. Tighten slightly more than hand tight.

5. Open air service shut-off valve.

6. Check for leaks and adjust as necessary.

Cleaning Steam Strainer

Strainer removes foreign matter from steam.
Frequency at which strainer must be cleaned is
dependent upon amount of foreign matter suspended
in steam. Removing and checking strainer screen for
cleanliness after two weeks or after 80 hours of
operation is recommended. If little or no foreign
matter has collected on screen, time between
inspections can be increased accordingly.

Cleaning Customer-Furnished Steam
Traps

Some steam traps are provided with internal steam
strainers. These strainers should be cleaned. Refer to
Cleaning Steam Strainer.

All repairable traps should be opened at least once a
year to visually check operating mechanisms.

Remove sediment and dirt from trap body. Mechanism
may require cleaning by immersing in appropriate
cleaning fluid.

NOTE: Check instructions provided with trap or
with trap manufacturer for appropriate cleaning
fluids.
