providing a dedicated circuit for this fan system. This model has two fan assemblies.
All electrical components, whether included with the VentCool system or supplied by others, must be rated for
the fan system's electrical load requirements; please refer to the VentCool Summit Series speci cations table

All wiring and connections must be made according to this manual and all applicable electrical wiring codes
and standards. All applicable electrical codes must be followed to the satisfaction of the local authority having

VentCool Summit Series Whole House Fan Systems are shipped with a pre-wired 20 foot 115VAC power cord
with Nema 5-15P plug and fan control module (FC3JF) prewired and installed on the fan assembly. The fan
assembly directly connects to the Vencool digital wall control (WTT) system via 50 foot Plug&Play (P&P) cable.
The P&P cable is equipped with RJ12 connectors that plug directly into the fan assembly control module
and backside of the wall control display. The wall control display is mounted in the living space and is used
