10. Troubleshooting
Hazardous live and moving parts are exposed
during the troubleshooting procedures.
!
WARNING
Power pack enclosure(s) service voltage is
120VAC. This can be lethal. Voltage (120 VAC)
is present within the power pack enclosure even
though the toggle switch is placed in the off
position.
RISK OF ELECTRICAL SHOCK.
The high voltage circuits to the ionizer and
collector should be grounded before removing
the power pack, high voltage wires, door feed
through insulators and unicell(s). The ground-
ing procedure can be accomplished by waiting
one minute after placing the toggle switch in off
position to the power pack enclosure or refer to
Figures 12 and 13. The power pack total current
output is limited to a maximum of 5 milliamps to
assure personnel safety.
Troubleshooting should only be completed by
qualified and trained personnel.

9.6 Blower Lubrication
The blower bearings require lubrication at a 2 to 3 month interval
(petroleum lubricant lithium NLGI grade 2 grease). The bearings
should be lubricated with the blower in operation. A hand
operated grease gun is required performing one to two injections
slowly, do not exceed two injections. Excessive injections/grease
will cause bearing seal failure, contributing to bearing failure.
9.5 Power Pack Enclosure Push Rod
Adjustment
Tools required:
• 6” adjustable or 5/16” open-end Wrench. Refer to Figure 9.
1. Close module door (10) with unicells installed.
2. Open power pack enclosure lid cover (3).
3. Loosen 5/16” hex jam nut (9), then back off push rod
extension (1) to end of threads.
4. Close power pack enclosure lid cover, listening for point
where limit switch (4) is engaged.
5. Adjust rod extension (1) inward until limit switch (4) engages
approximately one inch before the power pack enclosure lid
cover closes (3).
6. Tightened hex jam nut.
7. Close power pack enclosure pack lid cover (3) and latch.
To Change Gasket
Refer to Figure 15
1. Remove existing gasket, making sure to scrape off any residual
silicone sealant.
2. Trim one edge of gasket neatly and evenly.
3. The door gasket internally has three lips to one side of the gas-
ket and one lip to the other side. The door gasket should be
installed with the three lips towards the interior of the cabinet.
4. The door gasket should be formed to the complete cabinet
lip edge before applying silicone sealant. Place the trim edge
at the top center of the cabinet lip edge and press gasket
in place, ending at the same location. Do not trim excess.
5. Remove door gasket and apply silicone sealant to the inside
of gasket or on the inside edge of the cabinet lip edge. Place
the trim edge at the top center of the cabinet lip edge and
press gasket in place, ending at the same location, trim excess.
Remove excess silicone sealant and make sure the gasket
is firmly bottomed on the lip edge by tapping with a rubber
mallet or the gasket may not seal against the door properly.
6. Check that the distance from the inner face of the access door
to the latch tongue measures 7/8”. Slight adjustments may be
necessary due to sheet metal variations.
