Installation Instructions
IN019-1 Rev B
1.0 Auxiliary Fan Location
The auxiliary fan should be mounted with a minimum of 15 feet of ductwork from the outlet of the dryer to the inlet of the fan.
Failure to observe this distance may result in excessive lint build-up in the fan unit!
2.0 Auxiliary Fan Mounting
2.1). Install Mounting Bracket as shown. Attach the fan to the mounting bracket with (2) self-tapping
screws, provided, Avoid over tightening screws.
2.2) Attach bracket to mounting structure with the 1 1/4” screws provided. Connect the ductwork
between the outlet of the dryer and the inlet of the fan. Connect the outlet of the fan to the
termination ductwork. Seal the connections with duct tape or similar means.
3.0 Automatic Pressure Switch Installation
The pressure switch must be mounted vertically on a wall surface as near the outlet
of the dryer as possible. Mount the duct probe through the duct and connect with
tubing provided to the pressure switch.
Insure the arrow on the duct probe points toward the dryer and away from the
auxiliary fan to prevent lint from closing the probe.
4.0 Electrical Wiring
Electrical connection should be performed by a qualified person in accordance with all local, state and national electrical codes.
Make electrical connections to the pressure switch and auxiliary fan as shown in the following schematic:

5.0 Installation Troubleshooting
If the auxiliary fan fails to start when the dryer cycle begins check the following:
Verify the AC voltage at the pressure switch . The pressure switch-point is approximately 0.1” WC. The dryer must generate
this positive pressure to close the switch and start the auxiliary fan. If not, check the probe and connecting tubing for blockage.
You may blow gently into the tubing to check the switch operation.
If the auxiliary fan cycles on and off after the dryer cycle begins check the following:
The auxiliary fan may be generating sufficient negative pressure to overcome the positive pressure generated by the dryer. This
can be verified with a sensitive pressure measuring device or with an AC voltmeter at the pressure switch. Relocate the
auxiliary fan further away from the dryer and recheck.
6.0 Maintenance
Lint may accumulate inside the fan impeller and housing or on the automatic pressure switch probe. Periodic inspection and
cleaning should be performed every (6) months or as required based upon dryer usage.
Disconnect electrical power to the unit prior to inspection or cleaning.
NOTE: Excessive noise or vibration from the auxiliary fan may be an indication of lint buildup inside the fan impeller.
