Step 1—Checking Air Purifier Operation
WARNING
!
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.
a. Attach the Infinityt Air 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 Infinityt System Control to activate the
system fan.
c. Turn the Infinityt Air 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 Infinityt
Air Purifier power switch is set to off, when the blower
goes off, or when the HVAC system power is turned off.
Step 2—Infinity Control
a. When the Infinityt Air Purifier is used with an Infinity
Control, the Infinity Control can be configured to
remind the homeowner when it is time to change the
Infinityt Air 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 Infinity Control.
