Mount the valve on the water piping.
1
Install the o-ring in the water piping connection. In case of a
3-way valve, install the second o-ring in the second water
piping.
2
Install the valve on the inlet water piping
2-way valve
3-way valve
3
Connect the field piping.
The complete water circuit, inclusive all piping, must be
insulated to prevent condensation and reduction of the capacity
(minimum thickness: 10 mm).
If the temperature is higher than 30° and the relative humidity is
higher than 80%, the thickness of the sealing materials should
be at least 20 mm in order to avoid condensation on the surface
of the sealing.
4
Seal the valve and piping connections.
1
Add the "insulation for valve" (1) around the valve and the
sealing of the unit piping and the field piping.
2
Close the sealing off with the insulation tape (2).
Example: 3-way valve
Pay attention to the
mark on the 2-way valve
body.
The arrow must point inside the inlet water piping of the fan
coil unit.
Make sure the actuator is
not
installed upside down.
Pay attention to the
mark on the 3-way valve
body.
The long arrow must point inside the inlet water piping of
the fan coil unit.
In case 2 valves are installed on the same fan coil unit
(4 pipe model), use the same method described above to
install the second valve.

In case a 3-way valve is used, adjust the bypass opening
to regulate the pressure drop. See databook for more
