1. At the Air-Relay, disconnect the push-to-connect
tubing and check the trigger circuit (from the blast
control handle).
2. With the blast control activated, conrm that
there is air owing from the disconnected tube.
NOTE:NOTE:
NOTE:
The air ow should be at supply air
pressure but the air volume is reduced due to
the size of the ttings and tubing. If you do not
get supply air pressure, check the blast control
handle for proper operation, and check the blast
control hoses to make sure they are not kinked
or internally blocked.
3. Check the in-line lter at the industrial interchange
nipple connection on the side of the panel (where
you attach the blast control hose).
4. If the previous steps do not x the issue, replace
the air relay (Kit EQ5179).
