NOTE: If more that one whole house air cleaner is
installed, each unit will retain its own fault codes.
Examples: see Fig. 8
Ex. #1: The most recent fault condition was a High Voltage "HV
was Low"
Ex. #2: The second fault condition was "Internal Control Lock-

Ex. #3: The third fault condition was "Input Current too High"
To clear all three faults codes from the control's memory, press
and hold the RESET button for 2-4 seconds when the fault

SERVICE PROCEDURE
Repower Air Cleaner - check for normal
operation. Replace door if same fault comes
User set-ups 500 and 501 will need to be
changed back to "E" to enable the comfort
control to auto-discover the filter cleaning
timer set-up in the air-cleaner.
Check to see if buttons operate smoothly and
are not obstructed. If unable to free button
replace air-cleaner door
Air-cleaner can not generate a ERROR
CODE 91 on the comfort control, fault is with
other unit.
Active communicating fault. Check for 12-13
voltage DC between Brown and Blue wires at
the air-cleaner connection plug.
Like the furnace and air-handler's users
interfaces the air-cleaner stores fault codes.
Check air-cleaner COM LED for device count
(one blink for each communicating device on
the COM BUS) If device count is present
ensure air-cleaner green LED #1 blinks slow
with indoor blower operation. Clear fault log
Clean Collection Cells and Field Charger - If
they are clean, check for arcing through the
plastic frame.
Check for arcing through the Collection Cells
and Field Charger cases. Check door
operation by referring to Testing the Power
Door on page 17 of the air-cleaner's Service
Facts
Remove power door and recheck high
voltage-if still low replace power door, If
voltage is correct, check cells and Field
Charger.
Check for arcing through the Collection Cells
and Field Charger cases. Check door
operation by referring to Testing the Power
Door on page 17 of the air-cleaner's Service
Facts
Check Collection Cells and Field Charger
connector pins.
Clean Collection Cells and Field Charger.
Check for arcing through the Collection Cells
and Field Charger cases.
Check 24 volt supply to the air-cleaner. The
supply voltage should not drop below 22 volts
under full load. Ensure Transformer is rated
for at least 50VA for furnaces and 75 for air-
handlers. If two or more air-cleaners are
connected on a system, ensure the
transformer ratting is increased 25 VA for
each additional air-cleaner
