Humidex
9
Fasten Unit to the Wall
Now that the flex is tight, it can be attached to the elbow
with the tie wrap.
Flex should not be kinked in any way.
Leaving a 1-inch gap between the top of the unit and the
ceiling (In case of a finished ceiling, leave a 1/8-inch gap
between the top of the unit and the ceiling avoiding any
contact between the two) drill ¼” pilot holes through the
lips of the unit and the wall.
Apply the four plastics anchors on the wall with the help of a
hammer. Secure the Humidex to the wall using the four 1 ¼
inch screws provided.
Once the unit is properly installed, return outside, apply
exterior caulking, to the vent, to act as a weather seal.
NOTE:
If high winds are often present in the location of
the vent, they may cause a wind noise inside the house. If
this is the case, an
anti-gust hood
(AGH-990) is available
from your Humidex dealer.
Installing the CCC-103R
To allow the booster fan to draw air from the upper levels, a universal boot must be
installed. First cut out a whole to fit the universal boot.
Mount CCC-
103R booster fan on floor joist a minimum of 6’ away from the universal
boot to reduce noise. Connect universal boot to booster fan with a 6” insula
ted flex.
The CCC-103R booster fan must be plugged into the outlet located on the CCC-103E
unit.
Note:
An extension may be needed
A T-junction duct and flex can be added to the exhaust side of the CCC-103R to direct
air into all areas of the crawl space.
