WARNING
The Infinityt Air Purifier is equipped with a power indicator
light located on the door (see Fig. 13). This power indicator light
will illuminate when the Infinityt Air Purifier door is installed,
the power switch is in the on position, AND the fan coil blower is
running and airflow is sensed. If the power indicator light is not
illuminated, follow the troubleshooting steps below.
Step 1 —Check that the Infinityt Air Purifier door is installed.
NOTE: 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.
Step 2 —Check that the Infinityt Air Purifier power switch is in
the on (closed) position.
Step 3 —Confirm that the fan coil blower is operating.
Step 4 —Confirm that 208/230 VAC power is provided. Attach
power supply connector to the air purifier when the fan coil
blower is operating.
NOTE: Even though power is supplied to the Infinityt Air
Purifier, it will not turn on unless the airflow sensor senses
airflow or the airflow sensor’s bypass plug is inserted.
Step 5 —Confirm that the airflow sensor cable or airflow sensor
bypass plug is connected to the power supply (See Fig. 7).
Step 6 —If still not functioning, disconnect the airflow sensor
cable and the power cord from the power supply.
Remove the enhancement module from the air purifier cabinet
and inspect the airflow sensor (See Fig. 11).
Confirm the airflow sensor is properly seated in its bracket and
the airflow sensor cable is connected to the back of the sensor.
Replace the enhancement module.
Step 7 —Reconnect the power cord to the power supply and
insert the airflow sensor disable jumper (from parts bag).
If the power indicator light illuminates, then replace the airflow
sensor.
Install the door onto the air purifier and turn the power switch to
the “ON” position.
Step 8 —If all of the above steps are completed and the power
indicator light is still not illuminating, replace the power supply
on the enhancement module. Note that there are no serviceable
parts within the power supply.
