3. Installation work and electrical wiring must be done by a
qualified person(s) in accordance with all applicable codes
and standards, including fire-rated construction codes and
standards.
4. Sufficient air is needed for proper combustion and exhaust-
ing of gases through the flue (chimney) of fuel burning
equipment to prevent backdrafting. Follow the heating
equipment manufacturer’s guideline and safety standards
such as those published by the National Fire Protection
Association (NFPA), and the American Society for Heating,
Refrigeration and Air Conditioning Engineers (ASHRAE),
and the local code authorities.
5. When cutting or drilling into wall or ceiling, do not damage
electrical wiring or other hidden utilities.
6. Ducted fans must always be vented to the outdoors.
7. To reduce the risk of fire, use only metal ductwork.
8. If this unit is to be installed over a tub or shower, it must be
marked as appropriate for the application and be connected
to a GFCI (Ground Fault Interrupter) - protected branch
circuit.
9. Never place a switch where it can be reached from a tub or
shower.
10.This unit must be grounded.
1. For general ventilation use only. Do not use to exhaust
hazardous or explosive materials and vapors.

MOUNTING (New Frame Construction)
Factory-shipped unit installed in new construction.
MOUNTING (Existing Frame Construction)
Factory-shipped unit installed in existing construction.
Two ways to connect ductwork to a factory-shipped unit.
NOTE: Make sure the shipping tape is removed from the
damper flap and that damper flap opens and closes freely
inside the ductwork. Use duct tape to make ductwork
connections secure and air-tight.
WIRING
Ventilator can be wired from outside of housing.

USE AND CARE
Ventilator is designated for continuous operation. If desired, it
may be controlled using an on/off switch or a solid-state,
variable speed control. Follow wiring instructions packed with
control, and adhere to all local and state codes, and the
National Electrical Code.
WARNING: To reduce the risk of electric shock,
disconnect from power supply before servicing.
To clean blower assembly: Remove grille, unplug blower from
housing, remove blower mounting nuts, and carefully remove
blower from housing. Use appropriate vacuum attachment or a
soft cloth and mild soap detergent to clean blower discharge
area and wheel. NO NOT ALLOW WATER TO ENTER MOTOR.
Make sure blower assembly is completely dry before reinstalling.
Motor is permanently lubricated. Do not oil or disassemble motor.
