Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.

To replace the air purifier cartridge, complete the 

following steps:

Turn the heating and cooling system power off.

NOTE: 

Use  of  any  filter  cartridge  in  the  air  purifier  other  than  the

genuine  replacement  purifier  cartridges  listed  in  the  table  below  will

likely result in poor performance and may constitute a safety hazard. Do

not use any third-party air filters in the air purifier.

1. Turn the air purifier switch to the off position.
2. Remove the air purifier door.
3. Slide out the old air purifier cartridge and discard.
4. Install the new air purifier cartridge.

NOTE: 

Verify that the air purifier cartridge is installed correctly. Make

sure  that  the  arrows  on  the  air  purifier  cartridge  point  in  the  same

direction as airflow and match the arrows on the label on the cabinet.

5. Replace the air purifier door.
6. Turn the air purifier switch to the on position.
7. Turn heating and cooling system power on.

At the time of air purifier cartridge replacement, if a powdery residue is

noticed on the tips of the points in the ionization array, proceed to clean

them by completing the following steps.

Turn heating and cooling system power off.

1. Turn the air purifier switch to the off position.
2. Remove the air purifier door.
3. Slide out the Filter Enhancement Module (FEM).

4. Clean the FEM.

NOTE: 

Best cleaning tools: 5 inch (127 mm) handle paint brush with 2

inch (51 mm) width (or greater) brush point (synthetic or natural bristle)

or vacuum cleaner with brush attachment (

Fig. 19

).

Gently stroke the ionization pins with the brush. Use a gentle back and

forth brushing motion to clean any small accumulations from the tips of

the  points. If  desired, use  a vacuum  cleaner with  brush  attachment  to

gently vacuum the frame and components of enhancement module. Also,

if an Accessory Safety Screen is installed, vacuum the Safety Screen to

remove accumulated dust and debris.
If further cleaning of the FEM is needed, it may be washed with soap

and  water  and/or  rinsed  off  with  water.  It  should  not  be  placed  in  a

dishwasher or in boiling water. 

If  using  water  to  clean  the  FEM,  it  must  be  completely  dry  before

inserting back into the air purifier.
Additionally,  care  must  be  taken  when  handling  the  FEM  due  to  the

sharp points on the ionizer.

5. Slide in enhancement module.
6. Replace the air purifier door.
7. Turn the air purifier switch to the on position.
8. Turn heating and cooling system power on.

TROUBLESHOOTING

The air purifier is equipped with a power indicator light located on the

door (

Fig. 18

). This power indicator light will illuminate when the air

purifier door is installed, the power switch is in the on position, AND the

furnace blower is running. If a Flow Sensor Kit (model KIT160000) is

installed in the air purifier and there is no airflow, the power indicator

light will blink slowly (once every 3 seconds) indicating that the purifier

is in “STANDBY” mode.
