13.3.7 Symptom: The water pressure relief valve leaks
Installer reference guide
174
Possible causes
The valve (if equipped) of the water
circuit towards the expansion vessel is
closed.
The water volume in the installation is
too high
The water circuit head is too high
Possible causes
Dirt is blocking the water pressure relief
valve outlet
Corrective action
Open the valve.
Make sure that the water volume in the
installation is below the maximum
allowed value (see
"7.2.3 To check the
water volume and flow
"7.2.4 Changing the pre-pressure of the
4
expansion
vessel" [
70]).
The water circuit head is the difference
in height between the indoor unit and
the highest point of the water circuit. If
the indoor unit is located at the highest
point of the installation, the installation
height is considered 0 m. The maximum
water circuit head is 10 m.
Check the installation requirements.
Corrective action
Check whether the pressure relief valve
works correctly by turning the red knob
on the valve counterclockwise:
▪
If you do NOT hear a clacking sound,
contact your dealer.
▪
If the water keeps running out of the
unit, close both the water inlet and
outlet shut-off valves first and then
contact your dealer.
