!
WARNING
a. Attach the Perfect Airt Air Purifier door to the cabinet.
A magnet in the door (see Fig. 8) 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 unless
the safety switch is activated.
b. Turn the HVAC system power on and adjust the thermo-
stat or Evolutiont System Control to activate the system
fan.
c. Turn the Perfect Airt Air Purifier power switch to on
position.
d. The power indicator light above the Air Purifier power
switch should illuminate (see Fig. 13).
e. Check to ensure the light goes off when the Perfect Airt
Air Purifier power switch is set to off, when the blower
goes off, or when the HVAC system power is turned off.
NOTE: Upon power--up, the light will come on for
approximately 5 seconds and if no flow is detected, it will go off.
If no air purifier cartridge is detected, the flow sensor will detect
this and turn off after approximately 7 seconds.
Step 2
—Evolution Control
a. When the Perfect Airt Air Purifier is used with an Evolu-
tion Control, the Evolution Control can be configured to
remind the homeowner when it is time to change the Per-
fect Airt Air Purifier cartridge. This maintenance re-
minder can be based on either the TrueSenset 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 —Maximizing Performance
a. Maximum air purification performance is obtained when
the furnace blower is set for continuous operation on the
thermostat or Evolution Control.
