A) Replacing a Performance Light
Before replacing the performance light, turn OFF power
to the air cleaner at the source.
1. Remove the power box cover.
2. Disconnect the performance light wiring connected
to the LED terminals on the power board. Carefully
cut the wire es from the wire bundle.
3. Push the light out through front of power box.
4. Push the new light into the power box.
5. Connect the wiring to the LED terminals on the power
board. P3 - red; P4 - black. Route the wires away from
the high voltage wires or contacts.
6. Replace cover.
7. Return power to air cleaner. Test light.
B) Replacing a Power Board
Before replacing the power board, turn OFF power to the
air cleaner at the source or remove the plug.
1. Remove the power box cover.
2. Make note of posion of wires connected to the
LED, HV1, HV2 and 24 V terminals, then disconnect
these wires.
3. Remove the three hex nuts from the power board.
4. Remove the power board from the studs.
5. Place the new board onto studs with the 24 volt input
close to the transformer.
6. Replace the hex nuts removed in Step 3. Ensure the
star washer is in place over the steel spacer at the
ground locaon on the power board. For proper
grounding, the washer must be located on the top of
the steel spacer, under the power board.
7. Reconnect wiring to LED, HV1, HV2, and 24 V
terminals on the new power board.
8. Return power to air cleaner. Test power board.
9. Replace power box cover.
C) Replacing the 24 V Transformer
Before replacing the transformer, check the resistance
across the power board’s 24 V input terminals, without
the transformer connected. Resistance should read
above 20K ohms with an analog meter and above 4M
ohms with a digital meter. If the resistance readings are
below these values, the power board may be the cause of
the transformer failure.
Before replacing the 24 V transformer, turn OFF power to
the air cleaner at the source.
1. Remove power box cover.
2. Disconnect the secondary leads from the transformer
to the 24 V terminals on the power board. See Fig. 5.
3. Cut the primary leads (to the APS) close to the
transformer.
4. Remove the 2 hex head nuts from the transformer
studs.
5. Remove the transformer.
6. Place new transformer over studs and re-install 2 hex
head nuts to secure into place.
7. Connect secondary leads (white) to the 24 V terminals
on the power board (P1 & P2).
8. Wire nut primary leads from APS (cut in Step 3) to the
primary leads of the new transformer.
9. Replace power box cover.
10. Turn ON the power to the air cleaner and test
Note: The power board voltage has been set before
shipping. It is not usually necessary to reset the voltage
to the new load. If you do need to adjust the voltage,
refer to ⑤ Seng Voltage of Power Board in the
Troubleshoong secon for more informaon.
