Water connection, regardless of any options
•
A shut-off cock must be installed on the incoming pipe.
•
It is important that the water supply has sufficient pressure to ensure the
correct flow of water to the machine. The required water flow and pressure
can be found in the TECHNICAL SPECIFICATIONS. If the water pressure
is too low, a booster pump must be fitted.
The water pipe is connected at (1). The machine should be connected with a steel
braided and flexible hose. The hose’s internal diameter should be at least 9 mm.
It can be helpful to use the connection hose WD400125.31.
The water connection on the machine is fitted with a filter, non-return valve and
vacuum valve.

designated areas.
