4. Connect the transformer brown lead to the power supply P2 terminal. See Fig. 3 for internal schematic for the electronic air cleaner with conversion kit. CHANGE PLUG TO CONDUIT ! CAUTION ELECTRIC SHOCK HAZARD. CAN CAUSE ELECTRICAL SHOCK OR EQUIPMENT DAMAGE. Disconnect power before installing 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 ! CAUTION ELECTRIC SHOCK HAZARD. CAN CAUSE ELECTRICAL SHOCK OR EQUIPMENT DAMAGE. Disconnect power before wiring. 1. Attach conduit through a power box side knock-out. 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 power supply box, cover and access door. Fig. 2—Mount and wire transformer.

M5765A 3 69-0769—1 Checkout ! Checkout ! WARNING ELECTRIC SHOCK HAZARD. CAN CAUSE PERSONAL INJURY OR EQUIPMENT DAMAGE. The following procedures expose hazardous live parts. Disconnect from power supply between checks and proceed carefully. These instructions are for use by only qualified personnel. With all components in place, connect power to the air cleaner. Turn on the air cleaner switch to energize the system blower. Check the following points of operation: 1. 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. 2. Turn off the system blower. The neon light should go off after a few seconds. The neon light indicates that the air cleaner is energized and the high voltage power supply is working properly. 3. Turn on the system blower. With the 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. 4. With a multispeed blower, repeat steps 1 through 3 for each fan speed. 5. If operation is not as described, refer to the Electrical Troubleshooting section. Electrical Troubleshooting ! WARNING ELECTRIC SHOCK HAZARD. CAN CAUSE PERSONAL INJURY OR EQUIPMENT DAMAGE. The following procedures expose hazardous live parts. Disconnect from 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 (On Power Box) The neon light is powered through the power supply and is on when the power supply output voltage is normal. TEST BUTTON 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 (Air Cleaners with W8600E) 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 ! WARNING ELECTRIC SHOCK HAZARD. CAN CAUSE PERSONAL INJURY. Always turn off power and remove access door before removing power supply or its cover. The solid-state power supply within the power supply box 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 withi...
