Miele W 149 Washer User Manual


 
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
