INTERNAL SCHEMATIC FOR ELECTRONIC AIR CLEANER WITH W8600E.
The solid state power supply provided in this air cleaner has
no field-serviceable components. If troubleshooting indicates
a power supply problem, replace the entire power supply. See
Parts List section for order number.
To Access Power Supply
1. Turn off power.
2. Remove the access door and loosen the two screws
holding the power box. See Fig. 32.
3. To pull the plug connector out of the receptacle in the
junction box, lift slightly to clear screws, then pull the
power box straight toward you.
4. Take out the two screws holding on the cover. Remove
the cover.
5. Replace the power box by resting it on the cabinet,
lifting slightly to clear two screws, and pushing it
straight toward the junction box. Do not bend the spring
contacts sideways. The power plug must slide straight
into the receptacle.
6. Replace the access door and restore power.
