Grounding Instructions
This appliance must be grounded. In the event of
malfunction or breakdown, grounding will reduce the
risk of electric shock by providing a path of least
resistance for the electric current. This appliance is
equipped with a cord having an equipment-grounding
conductor and a grounding plug. The plug must be
plugged into an appropriate outlet that is properly
installed and grounded in accordance with all local
codes and ordinances.
Improper connection of the equipment-
grounding conductor can result in a risk of
electric shock. Check with a qualified
electrician or serviceman if you are in
doubt as to whether the dryer is properly
grounded.

Additional Grounding Procedure
Some local codes may require a separate ground. In
such cases, the required accessory ground wire,
clamp and screw must be purchased separately.
Never ground the dryer to plastic plumbing lines,
gas lines or hot water pipes,
Electrical Receptacle
The receptacle for the dryer cord must be located so
that the power supply cordwill be accessible when
the dryer is in the installed position.
Venting
The WTA 3500, electric vented dryer, is intended to
be vented to the outdoors.To prevent build-up of
moisture and accumulation of lint indoors, as well as
to maintain maximum dryingefficiency, it is
recommended that the Bosch WTA 3500 be vented to
the outdoors.
Ductwork
Four-inch (approx. 100 mm) diameter ducting should
be used. Use either rigid metal or flexible metal
ducting material. DO NOT use non-metal duct with
this dryer.
Exhaust ducts should be as straight as possible.
Exhaust ducting longer than recommended Can
extend drying time, can collect lint and may effect
dryer performance. Joints should be secured with
duct tape. DO NOT use screws to secure joints as lint
can collect on the screws. See Step 4, Exhaust
Duct, in following section titled INSTALLATION for
recommended routing and duct length calculations.
Exhaust Vent Hood
The exhaust duct must end with an approved exhaust
vent hood with swing out damper(s). DO NOT use an
exhaust vent hood with magnetic latches. To avoid
restriction of exhaust the outlet must be a minimum of
12 inches (30 cm) above ground level, or any other
obstructing surface. See Figure 7.
Condensate Drain
The WTL 5400, electric condensation dryer, dries by
condensing the moisture from the dryer air and then
pumping this condensate out of the dryer.
The WTL 5400 must have itscondensate hose
connected to a suitable drain. See Step 5,
Condensate Hose Connection, in the following
section titled INSTALLATION.

Checking/Installing Exhaust Ducting
The ducting system of the dryer, for optimum
performance, should be as short as possible with a
minimum number of elbows. Your WTA 3500 electric
vented dryer will work best when the venting system
has as few restrictions to the flow of air as possible.
Whether installingto an existing venting system or a
new venting system, make sure that all ducting is
clean and free of lint and does not exceed the length
per elbows as shown in Table 1, below:
Maximum length of duct
Number Rigid Flexible
of Elbows Duct Duct
030 ft. (914 cm) 20 ft. (610 cm)
1 22 ft. (670 cm) 15 ft. (457 cm)
2 14 ft. (427 cm) 9 ft. (274 cm)
3 6 ft. (183 cm) 4 ft. (122 cm)
Table 1.
Every elbow must have a minimum diameter of 4
inches (10 cm).
The above table assumes the use of an approved
exhaust vent hood with a swing out damper. DO
NOT use an exhaust vent hood with magnetic
latches. To avoid restriction of exhaust the outlet must
be a minimum of 12 inches (30 cm) above ground
level, or any other obstructing surface, as shown
below, in Figure 7.
