START- -UP AND OPERATION

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. 8) is used to activate a safety
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 Infinityt System Control to activate the system
fan.
c. Turn the Infinityt Air Purifier power switch to on posi-
tion.
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 Infinityt 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 —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.
