INITIAL START-UP:
With electrical power off, verify that the fan propeller turns freely
and that all fasteners are secure. Turn on electrical power and confirm that the fan
operates smoothly.
ADJUSTMENTS:
Set the fan control to the temperature shown on your ventilations system
drawing, or to a value which will provide the desired environmental conditions.
Single Phase Fans:
When variable speed controls are used, the fan's idle speed will need
to be set to the recommended minimum airflow rate. Refer to the procedures included with
each control. The table below provides airflow rates at various propeller speeds for fans
wired for 240 VAC.
