Problem Possible cause Corrective action
High temperature.
Bleed in ambient air and/or
replace with bags of high
temperature rated fabric.
Chemical attack. Contact us for recommendation.
8. Short bag life.
Localized wear from rubbing.
Straighten cages so that bags do
not rub against each other or the
collector housing. Replace bags
and corroded or broken cages.
Wear at air inlet may require an
inlet baffle.
“Power on” indicator light not
on.
Ascertain that timer “ON-OFF”
switch is on, that timer wiring is
connected, and that indicator
bulb is good. Inspect for blown
fuse. Replace with 3 amp., 3
AG fuse. Do not use slow blow
type.
9. Timer malfunction.
Solenoids skipping.
Establish power to solenoid and
proper wiring to timer. Check
solenoid and if O.K. change
wiring at timer to next unused
terminal and move program
wire to highest numbered
terminal used or replace timer.
If solenoid defective, replace.
Unusual readings.
Inspect gauge filter, replace if
plugged.
10. Unusual differential pressure
gauge readings.
Blocked gauge tubing.
Disconnect and remove
blockage. If blockage occurs
frequently, install filter and
replace it routinely.
