ELECTRICAL POWER AND CONTROL WIRING
The FAPV Power Ventilator may be set up to operate continuously with a 115 VAC power source alone, or to operate
intermittently as controlled by a ventilation controller having 24VAC output, such as the Field Controls model FAVC
Ventilation Control.
CAUTION: DISCONNECT AND TAG OUT ELECTRICAL POWER BEFORE BEGINNING INSTALLATION.

For Continuous (Standalone) Operation, refer to Wiring Diagram A:
For Continuous (Standalone) Operation, refer to Wiring Diagram A:
1.
Run electrical service to the FAPV fan unit installation area and install an electrical disconnect switch located
as required by all applicable national and local building and electrical codes.
2.
Label or mark the disconnect switch as "Mechanical Ventilation" to identify the switch as required by
ventilation codes.
3.
Remove the FAPV fi lter compartment cover by loosening the wingnut near the inlet collar.
the wingnut end of the cover away from the fan unit and pull it away from the electrical access cover to dis
engage the fi lter compartment cover from the electrical access cover.
4.
Remove the speed control knob on the FAPV fan unit by pulling it straight away from the FAPV electrical
access cover. Do not twist the knob while pulling.
5.
Remove the FAPV electrical access cover by removing the four #8 blunt-tipped screws from the cover.
6.
Run the electrical circuit from the disconnect switch to the FAPV fan unit through the strain relief/conduit
connector on the FAPV marked for 115 VAC wiring access and into the electrical compartment of the FAPV
(see Wiring Diagram A). If conduit is used on the electrical circuit, make sure to use an anti-short bushing on
the end of the conduit as required.
7.
Connect the ground conductor wire to the green grounding screw of the FAPV.
8.
Connect the 115V hot lead conductor wire to the M terminal of the FAPV (continuous ventilation only).
Connect the 115V hot lead conductor wire to the M terminal of the FAPV (continuous ventilation only).
9.
Connect the 115V neutral conductor wire to the N terminal of the FAPV.
10.
Verify that the blower wheel spins freely and is free from obstruction, and that the interior of the FAPV fan
unit is free of debris and other foreign objects.
11.
Tighten the conduit/strain relief connector clamp onto the electrical cable or conduit.
12.
Replace the electrical access cover of the FAPV fan unit using only the original factory blunt-tipped screws
that were removed from the cover.
WARNING: DO NOT USE INSTALLER-SUPPLIED SCREWS TO ATTACH THE ELECTRICAL ACCESS COVER TO THE FAPV.
