e. Check to ensure the light goes off when the Perfect Air 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.
Perfect Air Control
a. When the Perfect Air Air Purifier is used with an Perfect Air
Control, the Perfect Air Control can be configured to remind
the homeowner when it is time to change the Perfect Air Air
Purifier cartridge. This maintenance reminder can be based on
either the TrueSense
t
dirty filter algorithm or time. The in-
staller should use their discretion to select the most appropriate
option based on the initial system static pressure.
Maximizing Performance
a. Maximum air purification performance is obtained when the
furnace blower is set for continuous operation on the thermo-
stat or Perfect Air Control.
