Installation

Connection to water supply

The machine should be connected to a mains water supply in accordance with standard regulations. In Germany the washing machine is not required to have a non-return valve as it has been designed to comply with the relevant German DIN standard.

Connection to a household water soft- ener is not recommended.

Connection to the mains water supply should incorporate a mains stopcock with 3/4’’ thread. The stopcock should be fitted by a qualified plumber.

The approx. 2.5 m long 3/8" pressure hose should be connected to the stop- cock via the 3/4" threaded union. Please make sure the washer sits cor- rectly in the union.

A longer hose of 4 metres in length is available as an optional extra.

This pressure hose is not suitable for connection to a hot water supply. The connection point is subject to mains water pressure. Turn on the stopcock slowly and check for leaks.

If replacing the inlet hose only use a hose able to withstand pressure of at least 70 bar. This also applies to all fixtures and fittings used. Miele origi- nal parts are tested to this standard.

The machine is designed to operate with a water flow pressure of 1 bar mini- mum up to 10 bar maximum. The static water pressure must not exceed 10 bar. If it is higher than 10 bar it is essential to fit a reducer valve.

There is a minimum flow pressure of 1 bar pressure if, with the stopcock opened fully, 5 litres of water flow into a suitable container in 15 seconds.

The dirt filter in the open end of the inlet hose must not be removed as it pro- tects the water inlet valve.
