INSTALLATION INSTRUCTIONS
WARNING: TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK,
OR INJURY TO PERSONS, OBSERVE THE FOLLOWING:
A. Installation work and electrical wiring must be done by qualified
person(s) in accordance with all applicable codes and standards,
including fire-rated construction.
B. Sufficient air is needed for proper combustion and exhausting of
gases through the flue (chimney) of fuel burning equipment to prevent
back drafting. 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.
C. When cutting or drilling into wall or ceiling, do not damage electrical
wiring and other hidden utilities.
D. Ducted fans must always be vented to the outdoors.
E. 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 Circuit Interrupter) - protected branch circuit.
F. NEVER place a switch where it can be reached from a tub or shower.
G. Handle the sensor unit with care. Avoid direct contact with electronic
components while installing.
•
Do not install in a ceiling insulated to a value greater than R40.
•
Not for use in kitchens.
FOR BEST RESULTS
When installing the Ventilator in a new construction site, install
housing during the rough-in construction of the building. The blower unit,
sensor unit and grille should be installed after the finished ceiling is in
place.
To install a ventilator in an existing building requires an accessible
area (attic or crawl space) above the planned location.
This unit is designed to detect increased humidity levels and to
automatically activate the fan. For best results, the fan should be located
near the humidity source. Increasing the distance from the source will
lengthen the response time of the unit.
