Fan Interlock Method:
To prevent the heater from being energized unless the fan
is on, the heater includes two interlock methods: an airflow
switch, and the use of an auxiliary contact in the motor starter
contactor (3ph) or a fan relay (1ph).
Airflow Switch:
The airflow switch provides the best means of protection against
air failure caused by fan belt or other malfunction. Switches are
of the differential pressure, diaphragm-operated type and require
a minimum total pressure differential of .05" WC. The switch is
factory wired in series with the manual reset cutout.
