The VentCool ECM Summit Series Whole-House Fan Systems require a 115 volt electrical power supply of
minimum 15A ampacity and maximum 15 Amp circuit overcurrent protection.
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 for the electrical load requirements of the speci c model to be installed.
All wiring and connections must be made according to this manual and all applicable electrical wiring

location. Verify power voltage and terminal orientation.
2. In living area (upstairs living space), install a PLASTIC RETROFIT SINGLE GANG BOX
roughly 5 feet o the oor for the whole house fan wall controller to be mounted in
(Refer to FIGURE 4). DO NOT INSTALL METAL GANG BOX. Select a location that will
best sense the temperature for the living space. Do not install box in a location where
the temperature will be in uenced such as in direct sunlight, on an exterior wall, etc...
