ELECTRICAL HAZARDS
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
construction. Failure to do the installation properly can
result in fire or even death.
NOTE: A few hours of operation without apparent prob-
lems 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: Watch out for existing electrical wiring and other
utility wires or pipes when selecting a location for the fan.
Do not install the fan where there is electrical wiring in the
way. Select another location or have a qualified electrician
move the wiring to a different location.
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.
LACERATION HAZARDS
Danger: This fan has an unguarded fan blade. Do not
use in locations which are readily accessible to people or
animals. Do not let children play in an attic where this fan
has been installed. Contact with this fan while in operation
can result in injury or even death.
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.
Warning: This product has sharp metal edges that can
cut your hands. Wear canvas work gloves while handling
the fan during installation.
OTHER HAZARDS
Danger: For general ventilating use only. Do not use to
exhaust hazardous or explosive materials or vapors. Use
of this fan to exhaust hazardous, explosive or flammable
materials may result in a fire or explosion, causing injury
or death.
CARBON MONOXIDE HAZARD
Danger: Carbon monoxide is a colorless, odorless gas
that can kill. Carbon monoxide may be drawn into the
house by the operation of this fan if your fuel-burning
equipment is not properly maintained and vented or if
you lack adequate attic venting.
You should check the flue of your hot water heater and
furnace to see that the pipes are intact and sealed.
Request an inspection from your fuel supplier (gas comp-
any or heating oil company) or from a municipal building
inspector if you have any questions about the safety of
your fuel-burning exhaust system.
You must also check the number and size of your attic
vents. A total of at least 5.0 square feet (for Model PC15)
or 3.9 square feet (for Model PC12) of unobstructed vent-
ing must be available for safe operation of this ventilator. If
you have less than the amount specified above, STOP and
install additional vents before proceeding.
TOOLS NEEDED
