Solenoid valve

The thermostatic valve (TV) is used to control the water flow in order to keep a stable
machine temperature.

The factory default adjustment of the thermostatic valve (TV) is set in position 2 (approx.
75°C oil temperature).

The pressure switch (PS) is used to monitor the presence of water at the cooling system
of the machine.

When the pressure switch detects a pressure lower than 2 bar, the machine must be
stopped.

The water bypass valve (WBV) is used at the first machine start-up. At that moment it
should be open (approx. 90 seconds) to prime the water heat exchanger, afterwards it
should be closed.

The solenoid valve (MV) is used to stop the cooling water circulation when the machine
is not running.

• Connect the cooling water connections (CWI / CWO) to the water supply.

Connection size:

– 19 mm hose (CWI / CWO)

• If necessary, electrically connect the pressure switch (PS), see
