Re-install the PRE-FILTER and COLLECTION CELLS. Be
sure to fold the collection cell handles flat. Install the door
and plug in the power/control cable if removed. Turn on
power to the air cleaner.
NOTE: The first green LED will be on but will not flash for
the first 10 minutes the indoor fan is operating. This is a
drying cycle for the PRE-FILTER and COLLECTION CELLS
RESET TIMERS
To reset the PRE-FILTER timer, press and hold the RESET
button until the PRE-FILTER LED turns off. (1 to 2 seconds)
To reset the collection cell timer, press and hold the RESET
button until the collection cell LED's turn off. (4 to 5 seconds)
FAULT CODES
The air cleaner LED's will display a fault indication, three
yellow or three red LED's, when a fault has been detected. A
log of the last three faults is recorded and can be accessed
by going into the Set-Up mode. The unit will repetitively
check the system to determine if the fault persists. The fault
indication will be displayed as long as the fault condition
remains.
If the fault is no longer present, the system will return to
normal operation and no longer display the fault indication.
Even if the fault has been cleared, a log of the last 3 faults is
recorded.
REPETITIVE ARC FAULT INDICATION
If the unit detects 10 consecutive run cycles where an arc
occurs during the cycle, it will go into a lock out period for
one hour. This is indicated by three FLASHING YELLOW
LED's. The PRE-FILTER and COLLECTION CELLS should
be cleaned to ensure no large material is trapped in the
filters and causing the fault. Check the FIELD CHARGER for
material that can cause the fault.
If the unit detects any other type of fault, this will be indicated
by three FLASHING RED LED's. See the Service Facts for
fault code information.

FUSE REPLACEMENT
A fuse, located inside the Power Door, protects the power
supply components against damaging electrical currents.
This fuse has a rating of 3 amps and is a Purple color
automobile style fuse.
TO CHECK OR REPLACE THE FUSE
Disconnect the power cord from the front of the power pack
door. On the inside of the door remove the screws along the
outer edge to separate the metal door from the plastic cover.
The Purple Colored 3 amp fuse is located on the main printed
circuit board. Replace the fuse if blown and reassemble the
Power Door.
NOTE: When reassembling the inner panel to the Power
Door, ensure that the wiring is positioned to avoid interfer-
ence.
Re-install the door on the cabinet, plug in the power/control
cable and check for proper operation of the electronic air
cleaner.
The other electrical components inside the Power Door are
not field replaceable, the Power Door is available as a
complete assembly from your distributor.
