2.2.3 Connections
Water supply connection:
All machines are fitted with two water supply connections (hot and cold water). Please
consult manufacturer for optional soft water connection.
For machines with gas heating, it is important to ensure correct operation of boiler, to
supply water for washing step with a maximum TH of 10°. A higher TH will involve a
permanent clogging of boiler.
Install two pipes (hot and cold water) vertically behind machine; install two blocking
valves in an accessible location. Install a filter in each pipe, upstream from blocking
valves.
The pressure must be between 2 and 6 bars; install a motion absorber system as well
as an escape valve to handle high water pressure.

Drain connection
:
All machine types have 1 drain of diameter 80 (drainage of the tub).
The minimum cross section of the used water drain below the machine should be
respected (at least 150 x 150 mm).
Electrical connection:
Electrical power connection consists either of a cable with four wires, 230 V, three-
phase or of a cable with five wires, 400 V, three-phase.
