Installation

Assembly and disassembly should always be conducted when the system is cold and not under

pressure.

Accessibility: it is essential to provide unobstructed access to the valve for maintenance of the

valve or fittings.

1) The valve can be installed on both sides of the boiler, left- or

right side, in any position, vertical or horizontal.

2) Installation is recommended on the return to the boiler in

mixing mode (boiler protection).

Connections as follows:

- Hot water from boiler: inlet in the port marked with the

red dot (2) (see label).

- Cool system water return: inlet in the port marked with the

blue dot (1) (see label).

- Mixed water outlet, returning to the boiler, in the port

marked with the flame symbol on the valve body

3) Installation is allowed alternatively in diverting mode on the hot water pipe from the boiler.

Connections as follows:

Hot flow water from boiler: inlet in the port marked with the flame symbol on the valve body.

Outlet of the water towards the system flow: in the port marked with the blue dot (1) (see label).
