2. INSTALLATION

2-1 Installing the Hub

IMPORTANT: If you are installing the Hub onto an existing QuietCool fan, be sure

to shut off the power before attempting installation. If you are installing the Hub

onto a new fan, perform all installation steps before plugging in the fan.

1. Open up the thermostat on your attic fan. Unwire the power cord and remove the plastic

connector. Unwire the motor wires and remove the metal connector and flex from the

thermostat.

2. Attach the metal connector and flex to one of the knockouts on the IT-AF-SMT hub. Attach the

plastic power cord bushing in another knockout on the hub.

2-2 Wiring the Hub

NOTE: Wiring Diagrams are for examples only and wiring should be done

by an experienced electrician. 12 or 14-gauge romex is common. Check your

local building code before choosing the wire type.

NOTE: Ensure the power is disconnected before performing any wiring

connections.

NOTE: The wiring diagrams and instructions are shown using the power cord

included with your QuietCool. The installation can also be performed with

2-wire romex and hard wired.
