WARNING
TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK OR INJURY TO PERSONS,
OBERSVE THE FOLLOWING:
-
Installation work and electrical wiring must be done by qualified person(s) in accordance with
all applicable codes and standards, including fire-rated construction.
-
When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden
utilities.
-
Ducted fans must always be vented to the outdoors.
-
For exhaust fans, the discharge air is to be directed to the building exterior.
Ideal installation location
To determine the best location, examine the dwelling for an outside wall where you could install the
HCS-APT or HCS-APTHC. This location should be as far as possible from sources of
replenishment air such as windows, hallways and doors. Try to find a location where no electrical
wires or pipes are present inside the wall. The unit has to be installed on an outside wall.
Selecting the Duct Location
Now that you’ve decided where to install the unit, you must select a location for a 6¼” duct hole in
the outside wall. This hole is needed to pass a duct through the outside wall. Make sure that the hole
doesn’t line up with a stud, electrical wires, or pipe.
