Installation Instructions

Danger: The electrical installation and wiring of this fan
must be done by a qualified electrician in accordance with
all local codes and standards, including fire-rated construc-
tion. Failure to do the installation properly can result in fire
or even death.
NOTE: A few hours of operation without apparent
problems does not necessarily imply that the installation
is safe.
Danger: Do not substitute a solid-state speed control for
the thermostatically controlled on-off switch that comes
with this fan. Use of a solid-state speed control can result
in a fire causing injury or death.
Danger: Make sure the circuit breaker powering the circuit
on which the fan will operate is turned OFF before wiring
the thermostat. You can be shocked or electrocuted if the
breaker is not off.
8. CONTROLLER OPERATION FOR THE COMBINATION
HUMIDISTAT/THERMOSTAT
THERMOSTAT: The thermostat operates on a temp-
erature setting. Set the temperature dial to a 100 -110
degrees Fahrenheit setting. When the power ventilator is
operational, the fan should start automatically when the
attic temperature rises above the preset setting and cuts
off when the attic is cooled down to approximately 10%
below the thermostat setting.
HUMIDISTAT: The humidistat operates on a “fan-off”
setting. Recommended setting is midway between 7
and 8. This equates to approximately 75% relative
humidity. The fan will start automatically when relative
humidity rises 4% to 8% above the setting, and will
shut off when relative humidity reaches the setting.
The control is adjustable to provide flexibility of use.
Ground to screw on box.
Danger: Switch the power off at the service panel and
lock the service panel before servicing the motor. This fan
is thermostatically controlled—it may start at any time if the
power is not switched off at the service panel. Contact
with the fan blades while the fan is operating can result
in serious injury.
