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 can either be hard-wired or connected using a plug-
and-socket connection in accordance with IEC 60309-1. For a hard-
wired connection an all-pole isolation device must be installed on
site.
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.
An equipotential bond with good contact connection must always
be provided in accordance with all national and local regulations.
Accessories for equipotential bonding are not supplied and need to
be ordered separately.

Water connection

According to national regulations for drinking water quality, with ef-
fect from 21 March 2021, a non-return valve to prevent backsiphon-
ing must be fitted between the stopcock and the water inlet hose
during commissioning on all appliances in Germany. 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.
