1. When installing, keep the number of elbows and bends to a minimum. If necessary, long radius elbows or bends are recom-
mended.
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, Systemair FK clamps are recommended to connect duct
work to the fan (see illustration 2).
FK 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 form-
ing.
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.
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.
