Power Supply - Honeywell F58G Product Data

F58G COMMERCIAL DUCT MOUNTED ELECTRONIC AIR CLEANER1
Tools and Equipment
Troubleshooting the electronic air cleaner requires:
• Needlenose pliers for stringing ionizer wires and inserting
edge connectors.
• Ohmmeter.
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. The CHECK indicator
activates when the Test button is held down.
CHECK Indicator
The CHECK indicator activates to indicate the following
problems:
• Excessive dirt loading.
• Partial shorting of collector.
• Continuous ionizer or collector arcing.
• Power supply failure.

WARNING
Electric Shock Hazard.
Can cause personal injury.
Turn off power before accessing the power supply.
The solid state power supply can be replaced when
troubleshooting indicates a problem.
Troubleshooting Procedure
The electronic air cleaner troubleshooting diagram shows how
to quickly isolate a problem in the air cleaner. Although an
ohmmeter is needed in some steps, the primary diagnostic
tools are the status indicators and the Test button. See
Fig. 11.
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.
