Framing for Fan System
-
Frame opening for fan should be square and 1/2″ larger than fan size.(Example: For a 10″ fan, the rough opening should be 10½” x 10½”.)
-
Frame opening for intake shutters should be square and 1/2″ larger than the shutter size.
( Example: For 10″ shutter, the rough opening should be 10½” x 10½”.) Optional shutter locations shown with asterisk *()**. -
If trim and finish work is required around fan or shutter, then the frame opening is 3½” larger than fan or shutter size.
Fan System Options
Fan Speed Control
Provides variation of fan speed to match the season. High speed in summer,
slower in spring and fall, and very slow speed in winter to avoid sudden
chilling of the greenhouse.
Shutter Motor
Provides opening and closing of the shutter(s) and relieves starting load on
fan motor. Use only with heavy- duty, aluminum frame shutters. See Wiring
Diagrams, page 2.
WIRING DIAGRAMS
Basic Wiring
Adding Fan Speed Control
Adding Shutter Motors
IMPORTANT: FAN SPEED CONTROL must be installed only on the wire to the
fan, not to the shutter motors.
Adjust the speed set screw on the Speed Control to prevent the fan from
running below 1/3 of full speed (approximate).
FOR YOUR PROTECTION, ALL ELECTRICAL CONNECTIONS MUST BE MADE BY A QUALIFIED
ELECTRICAL CONTRACTOR.
