Be sure to inspect the unit before proceeding with these steps. Start with problem 1, then problem 2 and so on.
Table 1 – Troubleshooting
Problem: SPossible causes: SYou should try this:
1 Infinity Air Purifier power indicator light
located on the door is off.
SPower switch is not in the on (closed) position. SMake sure the switch is on and using a
multimeter check to see that 115 Volt power is
available.
SDoor is not closed. A magnet in the door is used
to activate safety reed switches in the power
supply when the door is installed.
SThe door magnet is missing or has fallen out. SRe-cement loose door magnet with a suitable
adhesive.
SThe door safety reed switches may be defective.
SIf the unit switch is on and 115 Volt power is
available through the service cord, a door
magnet moved in close proximity of the power
supply will cause the reed switches to audibly
click and the power supply will turn on.
SFurnace blower is not operating. Power will not
be supplied from the furnace control’s EAC
terminals unless the blower is running.
SMake sure the furnace blower is operating.
SBent pins or loose connection in the molex plug
of the service cord.
SReplace Service cord or replace entire power
supply / field enhancement module assembly if
required.
SThe power supply may be defective. SReplace entire power supply / field enhancement
module assembly.
SThe light pipe transferring the light from the
LED’s on the power supply to the door may be
broken.
SReplace access door.
2 Power Indicator light cycles on and off
intermittently.
SOverload condition activating the safety
circuitry S
SUnit is wet. (Water may be entering the unit from
a source such as condensate or dripping from a
frozen evaporator coil.)
SRemove the access door and the air purifier
cartridge. Power the unit then use a spare door
magnet or “service” magnet to activate the air
purifier power supply. Turn out the lights and
observe for arcing.
SGrounding paths in the unit are interrupted due
to breakage , corrosion or loose contact.
SMake sure all three grounding clips (FEM to
cabinet, safety screen to cabinet, cartridge to
cabinet on the leaving air side) are securely in
place and making clean contact.
SArcing to ground (such as unit cabinet ) is
occurring.
SMake sure the safety screen is clear and remove
debris.
SArcing to ground is occurring due to debris
lodged in the safety screen or across ionization
grid.
SMake sure the ionization grid is secured in place
with all four clips and centered in the FEM
housing.
SIonization grid is not centered or isloose and not
clipped in place, possibly touching the air
purifier cartridge or safety screen.
SVerify that the ionization grid is clean and intact.
SElectrode wire is loose and making contact with
the enhancement module wall.
SMake sure the field electrode wire is wound
through the spools on the enhancement module
with sufficient tension and tied to itself at the end
termination. If it is loose rewind and retie it.
SField electrode wire is damaged or nicked.
SIf the field electrode wire is damaged or nicked,
replace entire power supply / field enhancement
module assembly.
3 AirPurifier Cartridgehas smallsinge orchar
marks on the frame. SThe cartridge is installed backwards
STurn off the unit and remove the access panel.
SReplace the air purifier cartridge with Factory
Authorized Replacement Cartridge and ensure
airflow direction arrows are correct.
4 The wall control will not work.
SThe wire in the wall OR the wall control may be
defective.
SRemove the wall control and test it right beside
the unit using another shorter wire. If the wall
control works there, change the wire. If it does
not, change the wall control.
SThe wires may be in reverse position. SEnsure that the color coded wires have been
connected to their appropriate places.
SThewiresmaybebroken. SInspect every wire and replace any that are
damaged.
SThere may be a short-circuit. SWith the help of a multimeter, check for
continuity.
5 The 20-minute lighted push- button switch
doesn’t work OR its indicator light doesn’t
stay on.
SThe switch may be defective.
SJump the OL and OC terminals. If the unit
switches to high speed, then the wires are not the
problem. Replace the push-button.
SThe wires may be defective OR may not be
connected properly.
SEnsure that the color-coded wires have been
connected to their appropriate places.
