Installation; Install The Wall Switches - Broan PMA400SS Installation, Use & Care Manual

INSTALL THE DUCTWORK
(DUCTED INSTALLATION ONLY)
NOTE: To reduce the risk of fire, use only metal ductwork .
1 . Decide where the ductwork will run between the powerpack
insert and the outside . (FIG . 1)
2 . 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 airflow .
Refer to the table below to help you plan the most efficient

installation .

3 . Install wall cap or roof cap (sold separately) . Connect metal
ductwork to cap and work back towards the powerpack
insert location . Use 2" metal foil duct tape to seal the joints
between ductwork sections .
