Honeywell Air Flow Switch (AFS)
Note:
The last bypass procedure (1990 -2006) will light the neon indicator and bring the power supply to full power but it does
not fool the optional W8600F remote indicator. The LCD indicator will remain off itndicating the air cleaner is not running.
Permanently disabling the AFS is outlined the Honeywell F50F Product Data Manual, see page 11.
