Tip: We recommend connection to the power supply via a suitably
rated plug and socket which must be easily accessible for servicing
and maintenance work after the machine has been installed. An elec-
trical safety test must be carried out after installation and after any
service work.
The machine should be connected with a suitably rated plug and
socket in accordance with IEC 60309-1 or hard wired. For a hard
wired connection an all-pole isolation device must be installed.
For hard-wired machines connection should be made via a suitable
mains switch with all-pole isolation which, when in the off position,
ensures a 3 mm gap between all open contacts. These include cir-
cuit breakers, fuses and relays (IEC/EN 60947).
If the mains supply cannot be permanently disconnected, the isolator
switch (including plug and socket) must be safeguarded against be-
ing switched on either unintentionally or without authorisation.

If it is necessary to install a residual current device (RCD) in ac-
cordance with local regulations, a residual current device type B
(sensitive to universal current) must be used.
An existing type A residual current device (RCD) must be exchanged
for a type B RCD.

If local and national installation specifications require equipotential
bonding, good galvanic contact must be guaranteed. Equipotential
bonding must have an earth current rating > 10 mA.
Water connection
For compliance to Regulation 4 of the water regulations guide please
fit the supplied double check valves to the on-site water supplies for
each inlet hose used. The non-return valve prevents water from the
water inlet hose from flowing back into the on-site drinking water
supply.
Non-return valves are supplied.
The flow pressure must amount to a minimum of 100 kPa and must
not exceed 1000 kPa. If the flow pressure is higher than 1000 kPa, a
pressure reducing valve must be used.
The machine must be connected to the water supply using the inlet
hoses provided.
 The connection points are subject to water supply pressure.
Turn on the stopcock slowly and check for leaks. Correct the posi-
tion of the seal and screw thread if appropriate.
For the cold water connection one stopcock each with a 3/4" screw
thread is required.
If a water connection is not available, only a qualified installer may
connect the washing machine to the mains water supply.
