Filtration System Electrical Connections
The F500 has a 3-prong, 120 Vac connector plug with ground.
If further wiring is required, contact a qualified electrician to
make all electrical connections.
IMPORTANT
Be sure the unit is grounded correctly.
The F500 can be installed either to run continuously or to run
only when the HVAC system blower is operating.
• To run the air cleaner continuously, simply plug the air
cleaner into a 120 Vac outlet. The unit turns on and
operates continuously when the power switch is turned on.
• To run the air cleaner only when the system blower is on,
use an optional Honeywell S688A1007 Sail Switch in the
return air duct. See the S688A product literature for correct
installation procedures.
