Installer’s Guide
1. Power is not being supplied to the air cleaner.
A. Check that power switch is "ON "
B. Check that the power cord is connected to the outlet and the power door.
C. Check for voltage at air cleaner supply. If none, check fuse or
circuit breaker at power input line.
D. Check the fuse inside the power pack.
NOTE: Air cleaner should not be wired to fan motor taps or furnace control.
While observing the green operating light, push POWER switch to "OFF" position
and wait 30 seconds. Return POWER switch to "ON" position.
1. If the green light momentarily flickers when power is turned "OFF" or "ON",
check for shorted or wet cells.
2. If the green light illuminates for 10 to 20 seconds when power is turned "ON",
then turnd "OFF":
A. Check for obstruction in air flow sensor tube.
B. Check for missing or improper media filter.
C. Check for proper air flow or blower speed in return supply.
1. Check media filter for obstructions or excessive dirt. Clean filter.
2. Replace power tray.
Remove and check cells:
1. If dirty, clean cells thoroughly
NOTE: Ionizing wires should be clean with no build-up on wires.
2. Check for foreign material lodged in cells.
3. Check for loose or broken ionizing wires.
4. Check for cracked or broken insulators.

replacement. All power supply components are mounted on a
removable metal tray attached to the door. If a power supply fails,
the complete power tray must be replaced as a unit.
Input voltage
Furnace or Air Handler Units
120 VAC, 60 Hz
Air Handler Units
208 /240 VAC, 60 Hz
H.V. Output
6100 - 6800 VDC
CELL TEST
1.
Place collecting cell on a well insulated work bench with the
cell contact button pointing upward.
2.
Select a power pack that reads between 6100 and 6800 VDC
at the cell contact in an open circuit mode with the ozone
reduction jumper in NORMAL position.
3.
Place the power pack on top of the collecting cell ensuring
that there is proper contact between the cell contact and the
power pack contact.4. Apply appropriate voltage to power
pack. Turn On/Off switch “ON’
5.
Measure voltage at collecting cell ionizer or cell plates.
Voltage should be 6100 to 6800 VDC.
A.
If voltage is above 6100 VDC, test other cell (if appli-
cable).
B.
If voltage is below 6100 VDC, check cell as prescribed
in Checkout Procedure, Condition #1, Step #2.
NOTE:
When replacing collecting cells in cabinet, ensure
that the arrows on cells point in the same direction as the air
flow through duct work. Cell contact buttons must point
toward the power pack.
AIR FLOW MONITOR TEST
NOTE: The air flow monitor is a true differential pressure
sensor capable of operating in a completely sealed air
handling system. It is designed to operate in a return air
temperature range of 40° to 100°F. Operation outside this
range will cause the limit circuitry to shut down the power
supply until the return air temperature is within the operating
range.
When power is first applied and the circulating blower is off, the
green operating light should come on for about 10 seconds, then
go off. The operating light should then come on whenever the
blower is operating.
