WARNING
1. To reduce the risk of fire, this
dryer MUST BE EXHAUSTED
OUTDOORS.
2. To reduce the risk of fire, do
not use ducting longer than
recommended.
3. To reduce the risk of fire, only
use rigid or flexible metal duct.
4. DO NOT use a duct smaller
than 4 inches in diameter.
5. DO NOT use exhaust hoods
with magnetic latches.
6. DO NOT exhaust the dryer into
a chimney, furnace cold air
duct, attic, crawl space, or any
other ductwork used for
venting.
7. DO NOT install a flexible duct
in an enclosed wall, ceiling or
floor.
8. DO NOT crush or kink the
duct.
9. Do clean and inspect the
exhaust system on a regular
basis; at least once a year.
10. The exhaust duct must
terminate in a manner to
prevent back drafts or entry
of animals.
To prevent build up of moisture and
accumulation of lint indoors, as well
as to maintain maximum drying
efficiency, this dryer must be
exhausted outdoors.
Position the exhaust air duct so
i
that there is no counter
pressure (e.g. from wind) on the
exhaust outlet.
10
There are exhaust air outlets in the
rear panel of the dryer (1) and in the
left side wall (2).
d
Select the most suitable exhaust air
outlet after installing the dryer.
Change the exhaust tube to the
suitable position and cover the
other outlet with the fascia cover -
turn it in a clockwise direction.
Place the end of the exhaust air
duct in the air outlet without
bending the duct. Use duct clamp
to secure the air duct. The exhaust
air duct should only be positioned
horizontally or vertically and never
left to sag.
Ductwork
To ensure optimum performance,
the ducting system of the dryer
should be as short as possible with
a minimum number of elbows.
Your dryer will work best when the
venting system has as few air flow
restrictions as possible. Exhaust
ducting which is longer than
recommended may extend drying
time, cause lint to accumulate and
affect dryer performance and dryer
life time.
Whether connecting to an existing
venting system or a new venting
system, make sure that all ducting
is clean and free of lint.
The maximum permitted length for
both rigid and flexible metal duct is
shown in the tables below.11.
