6. Place the transformer on the mounting holes. See Fig. 2.

1. Remove the black wire from the power supply P1 terminal and place it on one of the transformer terminals.
2. Connect the transformer black lead to the power supply P1 terminal.
3. Remove the brown wire from the power supply P2 terminal and place it on the empty transformer terminal.
4. Connect the transformer’s brown lead to the power supply P2 terminal. See Fig. 3 for the internal schematic of the electronic air cleaner with conversion kit.

Change Plug to Conduit

Disconnect power before installing the replacement power supply board.

1. In the power box, remove and retain two wire nuts that connect the line cord leads to the power box wiring.
2. Remove the power green lead from the green grounding screw on the wiring compartment barrier.
3. Remove the power cord and the strain relief.
4. Put the provided plug in the hole left by the power cord.

Complete Wiring

1. Attach conduit through a power box side knockout.
2. Wire the air cleaner directly to the line voltage using wire nuts. See Fig. 3. Secure ground connection to the green ground screw on the wiring compartment barrier.
3. Replace the opowersupply box, cover, and access door.

1. INTERLOCK SWITCH.
2. OUTPUT REDUCTION JUMPER.
3. AIRFLOW SWITCH DISABLE JUMPER.

The following procedures for the Honeywell 203365A Electronic Air Cleaner expose hazardous live parts. Disconnect from the power supply between checks and proceed carefully. These instructions are for use by only qualified personnel.

1. With all components in place, connect power to the Honeywell 203365A Electronic Air Cleaner.
2. Turn on the air cleaner switch to energize the system blower. Check the following points of operation:
3. The neon light next to the on-off switch is on. If a W8600E is part of the installation, check the wall panel and make sure the ON LED is lit. The W8600E CHECK LED will come on if there is a problem with the high-voltage power supply.
4. Turn off the system blower. The neon light should go off after a few seconds. Turn on the system blower. With the Honeywell 203365A Electronic Air Cleaner energized, push the test button. A snapping sound indicates that the collector voltage is present on the cell. The W8600E CHECK LED will come on when the test button is held down.
5. With a multispeed blower, repeat steps 1 through 3 for each fan speed.
6. If the operation of the Honeywell 203365A Electronic Air Cleaner is not as described, refer to the Electrical Troubleshooting section.

Troubleshooting

The following troubleshooting procedures for the Honeywell 203365A Electronic Air Cleaner expose hazardous live parts. Disconnect from the power supply between checks and proceed carefully. These instructions are for use by only qualified personnel.

Tools and Equipment

• Troubleshooting the electronic air cleaner requires
• Needle-nose pliers for stringing ionizer wires and inserting edge connectors.
• Test meter.

Neon light

• The neon light is powered through the power supply and is on when the power supply output voltage is normal.

Test Buttons

• When pushed, the test button shorts from collector voltage to ground. The resulting arcing sound indicates that high voltage is being supplied to the collector.
• The solid-state power supply controls current flow to the collector. On air cleaners with a W8600E, the CHECK LED will come on when the test button is held down.

Check LED

The CHECK LED is on the W8600E. It lights to indicate the following problems: excessive dirt loading (beyond that required to activate the WASH LED), partial shorting of the collector, continuous ionizer or collector arcing, power supply failure, excessive ionizer current, or any condition causing a major reduction in high voltage.

Power Box

Always turn off the power and remove the access door before removing the power supply or its cover. The solid-state power supply within the power supply box of the Honeywell 203365A Electronic Air Cleaner can be replaced.

When troubleshooting indicates a power supply or solid-state performance indicator problem, replace the entire power box or replace the power supply within the box of the Honeywell 203365A Electronic Air Cleaner.

The Honeywell 203365A Electronic Air Cleaner troubleshooting chart shows how to quickly isolate a problem in the air cleaner. Although a meter is needed for some steps, the primary diagnostic tools are the neon light and the test button.
