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 equipmentgrounding 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 cord will 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 drying efficiency, 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 its condensate hose connected to a suitable drain. See Step 5,

Condensate

Hose Connection, in the following

section titled INSTALLATION.
