SAFETY INFORMATION
Warning and danger decals have been placed on the equipment to warn of potentially danger-
ous situations. Care should be taken to keep this information intact and easy to read at all times.
Replace missing or damaged safety decals immediately.
IMPORTANT!
Schaefer strongly recommends that a good alarm system be installed in connement build-
ings to warn of power failure and high temperature. Schaefer also recommends that an
alternate power source be available for connement buildings in case of power failure.
INSTALLATION INFORMATION
The installation information is the same for all polyethylene exhaust fans, unless otherwise noted.
Refer to the Rough-In Opening Dimension chart for the correct opening for your product.
Build wall framing to the required wall opening illustrated in the chart below. The fans are
shipped completely assembled and need only to be fastened to the wall framing with
the supplied fasteners.
INSTALLATION INSTRUCTIONS
1. After you have made the correct sized opening in the wall, the fan unit can be placed
into the opening and secured with lag bolts and washers (supplied) as in Figure 1.
2. There are two (2) shutter latches supplied with each fan which are used to hold the shutter
in place. These latches should be positioned with one on the top and one on the bottom in
the center hole of the fan panel. NOTE: Be sure to use two (2) washers for each shutter latch
(see Figure 1).
3. Flashing should be attached across the top of the fan on the outside of the building.
Caulking can be used on the sides of the fan housing to assure a tight seal.
4. Once the unit has been securely fastened to the wall, the fan is ready to be wired. As
shown in Figure 2, the electrical wire from the motor should be run through the wire
harness on the top inside of the fan housing and then through the notch in the
upper right of the shutter frame.

Instructions for Wiring
• Wiring should only be done by a trained electrician to prevent injury or death.
• Congure internal wires to match supply voltage and wire according to motor
nameplate. Test to verify correct rotation.
• Many of the electric motors in our fans are reversible. Make sure the fan is rotating in the proper
direction (see BLADE ROTATION ARROW LABEL on the fan housing). Follow instructions on the
motor label to change rotation if necessary.
• Schaefer recommends installing a lockable disconnect switch near each fan.
• Route wire to motor with drip loop and secure. Drip loop will drain accumulated moisture away
from the motor.
• Only permit power to unit when motor cover plate is properly installed to prevent injury.
