Problem Possible Cause Corrective Action
5. Final filters clogged,
powder in fan
compartment
Leaking cartridge filter gaskets, or
hole in filter media
Make sure the gaskets are sealing
correctly. If you can slip a
0.4 mm (0.015-in.) feeler gauge
between the gasket and the sealing
surface, tighten the tension screws to
compress the gaskets. Refer to the
Repair section for instructions.
If the gaskets continue to leak,
remove the cartridges. Clean and
inspect the gaskets, sealing surfaces,
and filter media. Replace the
cartridges if the gaskets or filter
media are damaged. Refer to the
Repair section. Replace clogged
final filters.
Leak in front plate of color module Locate and seal any leaks with RTV
sealant.
6. Cartridge filters
clogged
Pulse air pressure inadequate Increase the pulse air pressure or
volume. Decrease the pulse timer
delay (off time).
Powder too fine or contaminated Reduce the ratio of reclaim-to-new
powder. Check the powder particle
size. Replace contaminated powder
and fix the source of contamination.
Pulse valves out of position Position the valves as described in
the Repair section.
Timer board settings incorrect Adjust the timer board settings as
described in the Operation section.
Pulse valve or solenoid valves
clogged or malfunctioning
Open the pulse valve timer panel. If
you do not hear a pulse each time a
LED on the timer panel lights, the
solenoid valve connected to that LED
may have failed, or the pulse valve
connected to the solenoid valve may
have failed.
Follow these steps:
1. Check the wiring to the solenoid
valve.
2. Check for leaking compressed air
at the pulse valve. Repair or
replace as necessary.
3. Replace the solenoid valve if
necessary.
Powder level in color module too
high
Pump out excess powder.
Valve wiring failure or pulse valve
spring failure
Replace the valves.
