MOUNTING THE THERMOSTAT'S
OUTLET BOX

IMPORTANT: To assure proper operation of the
thermostat, it must not become covered by insulation and
must not be located adjacent to a heat source.

Secure the thermostat outlet box with screws or nails through
the mounting bracket and into wall stud or rafter. Position
flexible conduit so it does not touch fan sleeve.

ADJUSTING THE THERMOSTAT

The unit is shipped from the factory with the thermostat set at
110°F. The fan will automatically be turned on when the
temperature in the attic reaches 110°F and will automatically be
turned off when the temperature drops 10°F below the set
temperature. The “start” temperature setting may be adjusted to
any setting between 60° and 120°F.

WIRING

CAUTION: Be sure fan and switch are properly grounded
and all wiring complies with electrical code requirements for
120vAC, 15 amp circuit.

1. Refer to Figure 3. Run 120vAC wiring to the outlet box and secure

with standard box connector.

2. If desired, an on/off switch may be installed at a convenient location.

MAINTENANCE

CAUTION: Before cleaning or servicing unit, make sure
power is disconnected at service panel. (See important safety
instructions on page 1)

At the beginning of each ventilating season, check fan for any
debris that may be blocking fan blades, screen, or motor
ventilation openings.

To extend motor life, lubricate motor at the beginning of each
ventilating season. Oil ports are located on the front and back of
the motor. Use 5 or 6 drops of 20W non-detergent motor oil in
each port.
