766788 prioAir OIPM

4
The prioAir ventilation fan may be mounted in either the
horizontal or vertical orientation. Each fan is designed with a
series of mounting holes, patterned around the center axis of
the fan which provides optimum control of the electrical box
orientation during installation. All prioAir units come standard
with a mounting bracket (shown below) and mounting
hardware.
Mounting options
1. When installing, keep the number of elbows and bends to a minimum. If neces-
sary, long radius elbows or bends are recommended.
2. Duct Sealant, caulk, or tape should be applied to all seams to prevent air leakage
and maximize air performance.
3. Flex, spiral, or snap lock ducting may be used. If using rigid duct, FC clamps are
recommended to connect duct work to the fan (see above illustrations).
4. To minimize static pressure losses and promote adequate airow, minimize duct
run lengths where possible. If using ex duct, keep duct runs straight and taut.
5. If installing in an unconditioned space, covering the fan with insulation is recom-
mended to prevent condensation from forming.
6. For general ventilation applications, at least 8 ft of insulated exible duct shall be
installed between the exhaust or supply grille(s) and the fan.
