START--UP AND OPERATION
Step 1 —Checking Air Purifier Operation
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal
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 Airt 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 Evolutiont System Control to activate
the system fan.
c. Turn the Perfect Airt 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
Airt Purifier power switch is set to off, when the
blower goes off, or when the HVAC system power is
turned off.
Step 2 —Evolutiont Control
a. When the Perfect Airt Purifier is used with an
Evolutiont Control, the Evolutiont Control can be
configured to remind the homeowner when it is time to
change the Perfect Airt Purifier cartridge. This
maintenance reminder 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 Evolutiont Control.
