SP Ceiling Exhaust/Inline Fans, Rev. 3, November 2013
Potential Solution
Check for an open fuse or circuit breaker in the building's service panel.
Check that the two (2) plug-in connections for the Motor and the Control are seated
firmly in place.
Check that the Blower Wheel spins freely.
Check that the back draft damper in the fan's Duct Connector pivots freely. Screws used
to attach the duct to the Duct Connector may be preventing the damper from opening.
Check that the back draft damper in the wall or roof cap pivots freely. These dampers
are sometimes mistakenly painted shut or obstructed by bird and insect debris.
For spot ventilation, turn both the master switch and the mode select switch ON to
enable the fan to run at the certified airflow rate.
For spot ventilation followed by continuous ventilation, increase the "TIME" setting of the
user-adjustable time delay.
For continuous ventilation, increase the "CFM" setting of the user-adjustable airflow rate.
To Change Bulbs
Refer to Retrofit Installation Step 14 (page 11).
