TROUBLE SHOOTING – COLLECTOR
(continued)
COLLECTOR - SYMPTOM
POSSIBLE CAUSE(S)
REMEDY(S)
Cartridge filters clogged due to:
Failure to pulse filters
Pulse the filters several times.
Inadequate pulse pressure
Increase the manifold pressure to
60-90 psi (4.14-6.20 bar).
Powder too fine or contaminated
If using reclaimed powder,
reduce the ratio of reclaimed-to-
virgin powder. Check powder
particle size, if necessary.
Pulse valve malfunction
The pulse valve diaphragm is
ruptured. If you hear a hissing
sound inside of the fan section,
check for constant air flow from
the valve. Replace the damaged
valve.
Cross drafts
Check for cross drafts across the
booth face and correct as
necessary.
Parts too large, interrupting flow
of air through booth
Contact your ETI representative.
Powder escaping from booth
openings
Exhaust fan rotation reversed
Reverse the rotation of the motor
by switching the wiring.
No power to unit
Check to make sure power
connections are good and there is
incoming electrical power.
Fan motor overload shutdown
Correct one of the following
possible motor, contactor, fuse or
operational problem as needed:
•
Check the exhaust fan for
proper rotation direction.
•
Check for mechanical binding
of the motor/fan assembly.
•
Re-set Manual Motor Starter
and turn unit back ON. If
problem persists, contact
E.T.I.

Incorrect, shorted, or open
electrical wiring
Check the electrical circuits.
