1 SAFETY

1.1 Safety instructions

Attention

Repairs may be carried out by a qualified electrician only! The user may be put at risk and injured by improper repairs! To prevent electric shocks, always comply with the following instructions: If the appliance is faulty, the housing and frame may be live! Electric shock may occur if live components are touched

inside the appliance! Before commencing repairs, disconnect the appliance from

the power supply! If tests have to be performed while the appliance is live,

always use a residual-current-operated circuit-breaker! The protective conductor resistance must never exceed the

values specified in the standard! The protective conductor is crucial for personal safety and appliance function.

When repairs are complete, perform a test in accordance with VDE 0701 or the corresponding national regulations!

When repairs are complete, perform a function and leak test.

Comply with the following instructions:

Conduct the safety test in accordance with VDE 0701 via the connector as follows: The differential current must be measured on the appliance! See circuit diagrams test programme The following pictograms are used in the repair instructions:

Electrostatic sensitive devices! Please observe handling regulations!

Sharp edges: Wear protective gloves.

1.1.1 Description

Electrostatically -

Endangering -

Components

1.1.2 Generally

Economy, environmental protection, control comfort, high functionality and working reliability are realized with electrical household appliances by the insertion of most modern electronics. This high-quality technology requires a professional handling and a competent specialized knowledge. All electronic modules are equipped with components, which are endangered by an electrostatic voltage.

1.1.3 Endangered coponents

The following elements are endangered by electrostatic voltage: µ Processors and IC`s Transistors, thyristors and Triac`s Diodes

1.1.4 Causes and effect

They lead an electrostatic voltage with itself: of up to 35,000 V, if you walk over a non conductive carpet, of up to 12,000 V, if you walk over a non conductive PVC soil and of up to 1,800 V, if you sit on a padding chair. The electrostatic voltage of their body is passed to electronics and EEC`s affected by them, which are possibly damaged thereby.

Dead A defect part A defect component A defect appliance

Slightly hurt Damaged Weakened Early failure

58300000112796.doc – 05.03.10 Seite 4 von 45

1.1.5 EEC – Notes

On all electronics modules and electronics components are electrostatically endangered elements . For the protection of these electrostatically endangered elements the following measures are to be met: Noticing the appropriate marking of the components and modules: Put on before contact and measurement of the EEC`s a electrostatics protective system (bracelet with grounding component). Avoid the contact of EEC`s with rechargeable plastics (foils etc.). Components, modules and PC-boards are to be touched in such a way that the conductive strips or connections are if possible not affected. EEC`s may arrive not too close at monitors and televisions. Use for transport only conductive materials or the original packaging.

1.1.6 Electrostatics protective system

The electrostatic voltage of the body is derived over the bracelet and the grounding component. This takes place for safety reasons not directly, but over a resistance combination. The ground connection and/or protective grounding binding must be perfect!

2 INSTALLATION 2.2 Drainage fittings / Connection

Do not extend the drainage hose (2 m). 2.1 Installation / Connection If connection (1) is to a wash-basin, the max. height is 100 cm

Place the dryer on a level and firm surface. If the drainage hose is connected to a siphon (2), the height must not be less than 70 cmA lower height may cause dirty water to flow back into the appliance via the drainage hose.

Level the dryer with the four height-adjustable feet. (Use a spirit level) do not remove the height-adjustable feet.

The dryer can be installed in combination with a washing

machine (front loader)To ensure a secure connection, use the original connection sets (see operating instructions).

The installation location must be supplied with adequate fresh air (open window or door).

Do not block the cooling-air grille on the front of the dryer,

otherwise adequate cooling air cannot be drawn in. 1 Max. 100cm

2 Min.70cm Do not install the dryer in a room where there is a risk of frost.Freezing water may damage the appliance. Order number: see circuit diagrams

The temperature mast higher than 5°C.
