Fan is a 3-speed fan controlled by a 4-position switch as follows: OFF - HI - MED - LOW - OFF. Select speed as required by pulling the chain
in the hallway. Shutter opens and closes automatically as fan is turned on or off. Shutter will open on any fan speed; however, at low speed,
complete opening could take up to one minute. We suggest you run the fan at high speed for 30 - 45 seconds to insure the shutter is com-
pletely open before switching to a lower speed.
