START-UP and OPERATION
Checking Return Air Purifier Operation
1. Turn the HVAC system power on and adjust the thermostat or
System Control to activate the system fan.
2. Turn the Return Air Purifier power switch to ON position.
3. The green indicator light on the power supply door should
illuminate ( Fig. 17 ).
This green indicator light will illuminate when the Return Air Purifier
door is installed, the power switch is in the ON position AND the
furnace blower is running. The indicator will be OFF when the furnace
blower is not running.
NOTE: For information on the green indicator light status and error
conditions, See Table 1 for status codes or Table 2 for error codes in

Control
When the Return Air Purifier is used with a Communicating Wall
Control, the Control can be configured to remind the homeowner when it
is time to change the Return Air Purifier cartridge. This maintenance
reminder can be based on either the TrueSense™ dirty filter algorithm or
time. The installer should use their discretion to select the most
appropriate option based on the initial system static pressure.
Maximizing Performance
Maximum air purification performance is obtained when the furnace
blower is set for continuous operation on the thermostat or Control.
MAINTENANCE
The Return Air Purifier is designed to require minimal maintenance.
Maintenance is limited to the periodic replacement of the air purification
cartridge and inspection/brush cleaning of the ionization array.
Frequency of cartridge replacement and cleaning of the ionization array
may vary depending on ductwork design and local environmental
conditions, generally 6-9 months.
To replace the Return Air Purifier filter cartridge,
complete the following steps:
Turn the heating and cooling system power off.
IMPORTANT: Use of any filter cartridge in the Return Air Purifier
other than the genuine replacement purifier cartridge 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 Return Air Purifier.
1. Open the return air grille cover.
2. Unlatch the unit and slowly lower the inner purifier unit. This will
disable the power.
3. Slide out the old cartridge and discard.
4. Install the new filter cartridge (
Fig. 18 ).
IMPORTANT: Make sure the metal tabs on the leading edge of the
filter case are inserted first. They must not be visible after the filter is
installed. Follow the instructions printed on the filter cartridge ( Fig. 19 ).
Otherwise, the unit will not operate properly.
