Startup and Operation
Checking Air Cleaner Operation
WARNING: Electrocution 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
disconnect switch.
a. Attach the Honeywell Enhanced Air Cleaner door to the cabinet. A magnet in the door (see Fig. 16) is used to
activate a safety switch in the power supply when the door is installed. The power supply will not energize the
air cleaner unless the safety switch is activated.
b. Turn the HVAC system power on and adjust the thermostat to activate the system fan.
c. Turn the Honeywell Enhanced Air Cleaner power switch to on position.
d. The power indicator light below the Honeywell Enhanced Air Cleaner power switch will illuminate (see Fig. 17).
e. Check to ensure the light goes off when the Honeywell Enhanced Air Cleaner power switch is set to off, when
the blower goes off, or when the HVAC system power is turned off.
NOTE: Upon powerup for the FH8000A models, the light comes on for about 5 seconds and, if no flow is
detected, it goes off. If no air filter cartridge is detected, the flow sensor detects this and turns the
Honeywell Enhanced Air Cleaner off after about 7 seconds.
