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 circuit
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 being
switched on either unintentionally or without authorisation.
If it is necessary to install a residual current device (RCD) in accord-

ance 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 necessary, equipotential bonding with good galvanic contact must

be guaranteed in compliance with all applicable local and national in-
stallation specifications.
Equipotential bonding must have an earth current rating > 10 mA
Accessories for equipotential bonding are not supplied and need to
be ordered separately.

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.
Only connect the washing machine to the water supply with the hoses
supplied.
