injury or death.
Before installing or servicing system, always turn off
main power to system. There may be more than one (1)
disconnect switch.

WARNING
a. Attach the Perfect Air
t
Purifier door to the cabinet. A
magnet in the door (see Fig. 9) is used to activate a safe-
ty switch in the power supply when the door is installed.
The power supply will not energize the air purifier un-
less the safety switch is activated.
b. Turn the HVAC system power on and adjust the
thermostat or Evolution
t
System Control to activate
the system fan.
c. Turn the Perfect Air
t
Purifier power switch to on
position.
d. The power indicator light above the Air Purifier power
switch should illuminiate (see Fig. 8).
e. Check to ensure the light goes off when the Perfect
Air
t
Purifier power switch is set to off, when the
blower goes off, or when the HVAC system power is
turned off.
Step 2

t
Purifier is used with an
Evolution
t

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.
Step 3
