Troubleshooting Procedure

The electronic air cleaner Troubleshooting chart shows
how to quickly isolate an air cleaner problem. The primary
diagnostic tools are the neon light and the test button.
Some steps require a meter. See Fig. 7.
TO USE THIS CHART:
1. FOLLOW THE STEPS IN ORDER; DO NOT SKIP AROUND.
2. EACH TIME YOU ISOLATE AND FIX A PROBLEM, GO BACK TO START.
3. REPEAT ALL THE STEPS UNTIL THE AIR CLEANER CHECKS OUT OK.
THESE SERVICING INSTRUCTIONS ARE FOR USE BY QUALIFIED PERSONNEL
