Plumbing
This machine is approved for all UK ap-
plications as suitable for category 5.
Product is listed in the WRAS regula-
tions advisory scheme directory and is
suitable for direct connection to mains
drinking water. No special plumbing ar-
rangements e.g. break tanks are re-
quired.
A Water Council approved check valve
is supplied in the accessories pack
provided with this machine. It should be
fitted in between the stopcock(s) and
the water inlet hose(s).
The machine should be connected to
the water supply in accordance with lo-
cal and national safety regulations.
Connection to the water supply should
be carried out by a qualified plumber
and should incorporate a stopcock with
a 3/4" thread.
The machine is supplied as standard
with two hoses, for connection to a hot
and cold water supply.
Connection to cold water supply
The approx. 1.5 m long
3
/
8
" pressure
hose (blue stripes) should be con-
nected to the check valve on the stop-
cock via the
3
/
4
" threaded union.
This hose is
not
suitable for connection
to a hot water supply.
Make sure that the washer sits correctly
in the union.
The connection points are subject to
water pressure. Turn on the stopcock
slowly and check for leaks. Correct the
positioning of the washers and screw
unions if appropriate.
If replacing the inlet hose only use a
hose tested to withstand pressure of
at least 70 bar. This also applies to all
fittings used. Miele original parts are
tested to this standard.
Longer hoses 2.5 or 4.0 m in length are
available as optional extras.
The pressure hose and solenoid inlet
valve are designed for a water flow
pressure of between 1 and 10 bar. At
higher water pressures it is essential to
fit a reducer valve.
There is a minimum flow pressure of 1
bar if 5 litres of water flow into a suit-
able container in 15 seconds.
