Air extraction mode
Non-return flaps
^ Place the non-return flaps into the
exhaust connections at the top of the
motor assembly so that the flaps
open in the "up" direction.
^ Turn the non-return flaps slightly to
the left to lock them in place.
Reducing collar
^
If using 5" (125 mm) ducting, place
the reducing collars into the exhaust
connections and turn left to lock them
in place.
Exhaust connection
^
Connect the ductwork to the exhaust
connection using appropriate
measures for the type of ductwork
being installed (hose clamp, duct
tape, etc.).
Note
: A Y- adapter may be used to feed
the exhaust from both exhaust
connections into a common duct.
