WARNING 
TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR 
INJURY TO PERSONS, OBSERVE THE FOLLOWING: 
1. 
Use this unit only in the manner intended by the 
manufacturer. If you have any questions, contact 
the manufacturer. 
2. 
Before servicing or cleaning unit, switch power 
off at service panel and lock the service 
disconnecting means to prevent power from 
being switched on accidentally. When the 
service disconnecting means cannot be locked, 
securely fasten a prominent warning device, 
such as a tag, to the service panel. 
3. 
Installation work and electrical wiring must be 
done by qualified person(s) in accordance with 
all applicable codes and standards, including 
fire-rated construction. 
4. 
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 local code 
authorities. 
5. 
When cutting or drilling into wall or ceiling, do 
not damage electrical wiring and other hidden 
utilities. 
6. 
Ducted ventilating fan must always be vented to 
the outdoors. 
7. 
Do not install this ventilating fan where air 
temperature may exceed 40°C (104°F). 
8.

it must be marked as appropriate for the 
application and be connected to a GFCI (Ground 
Fault Circuit Interrupter) – protected branch 
circuit. 
9. 
These models are UL listed for tub and shower 
enclosures. 
10. 
Do not use this unit with any other solid-state

Before servicing or cleaning unit, switch power 
off at service panel and lock the service 
disconnecting means to prevent power from 
being switched on accidentally. When the

securely fasten a prominent warning device, 
such as a tag, to the service panel. 
12. 
NEVER place a switch where it can be reached 
from a tub or shower.
