Installation
1. When installing, keep the number of elbows and bends to a minimum. If necessary, long radius elbows or bends are recommended.
2. Duct sealant, caulk, or tape should be applied to all seams, including around the opening in the wall or ceiling on the interior and around exterior
building penetrations, to prevent air leakage and maximize air performance.
3. Flex, spiral, or snap lock ducting may be used. If using rigid duct, Fantech FC clamps are recommended to connect duct work to the fan (see
illustration 2). FC clamps make an air tight seal at the connection points and reduce vibrations transmitted throughout the duct system.
4. To minimize static pressure losses and promote adequate airflow, minimize duct run lengths where possible. If using flex duct, keep duct runs
straight and taut.
5. If installing in an unconditioned space, covering the fan with insulation is recommended to prevent condensation from forming.
6. For general ventilation applications, at least 8 ft of insulated flexible duct shall be installed between the exhaust or supply grille(s) and the fan.
7. A 4 inch rigid duct recommended for best performance.
The unit should only be installed in a ceiling. The size of joists should be at
least 2" wide and 4" high . The space between two joists should be 16".
From the above surface of the suspended ceiling there should be minimum
9" distance to the roof. (Figure 2) Select the suspension brackets as
shown in (Figure 3)

Step 1.
Remove the grille by gently squeezing the wire springs and extracting
them from the slots in the housing.
Step 2.
Remove the wire box cover and install the 3 brackets on the fan housing.

The ducting from this fan to the outside of the building has a
strong effect on the air flow, noise and energy use of the fan.
Use the shortest, straightest duct routing possible for best
performance, and avoid installing the fan with smaller ducts than
recommended. Insulation around the ducts can reduce energy loss
and inhibit mold growth. Fans installed with existing ducts may not
achieve their rated air flow.
