INSTALLATION
The Air Booster is not designed for installation in
the main air supply ducts. Locating the Air
Booster near the outlet end of a problem branch
duct will provide the best performance.
The Air Booster is designed to operate in round
ducts 6-inches in diameter or larger and
rectangular ducts 6-inches wide by 6-inches
deep or larger.
CAUTION: Do not install the Air
Booster where the air temperature
within the duct exceed 180
Air Booster should not be installed
into vertical duct pipes.
1. Locate the Air Booster in the
duct pipe near the problem
area. Allow adequate space for
the removal of the unit for
servicing or annual inspection.
2. Attach
the
self-adhesive
template provided to the duct
surface. Make sure the arrows
on the template point in the
direction of the desired air flow.
After the template has been
secured to the duct pipe, cut a
slot in the pipe along the
indicated lines on the template.
Then remove the remainder of
the template from the pipe.
(See Figure 1A or 1B)
3. Insert the Air Booster into the
slot, making sure the fan blade
points in the direction of the air
flow. Position the Air Booster so
the fan blade does not rub
against the inside surface of the duct. Mark on the duct the location of the 6-hole positions in the base plate. Remove
the Air Booster and drill 1/8-inch diameter holes through the duct pipe where indicated.
4. Remove center knockout from the installer supplied outlet box bottom. (See Figure 2A) Before installing Air Booster
into the duct pipe, fasten the outlet box onto the base plate with the #10-32 UNF screws and nuts provided. (See
Figure 2B)
5. Insert the Air Booster into the cut slot of the duct pipe. Make sure the fan blade is pointed toward the outlet of the
duct. Secure the Air Booster onto the duct with the sheet metal screws provided. (See Figure 3A or 3B)
