WIRING AND START UP

DO NOT PLUG THE AIR CLEANER INTO AN OUTLET THAT IS
ALWAYS LIVE. The outlet must only be live when the HVAC
system fan is operating. Failure to properly wire the outlet
can result in excessive ozone production.

slowest fan speed) and verify that the blue light on the door
is not on (see FIGURE 13) .
7. Turn ON the door switch .
8. Verify that the blue light on the door turns on (see
FIGURE 13) .
9. If the light is on, turn off the heating or fan and verify
that the light on the door turns off . If the light turns off,
installation is complete . If the light on the door does not turn
on and off as described, continue with Step 10 .
10. If the light stays on after the blower has stopped running,
the outlet is continuously live and must be rewired in
accordance with Step 1 .
11. If the light flashes on, then turns off, or if the light does not
come on at all, refer to the TROUBLESHOOTING GUIDE on
page 9 .
