NOTICE
Do NOT use excessive force when connecting the piping. Deformation of the piping
can cause malfunctioning of the unit.
To facilitate service and maintenance, 4 shut-off valves and 1 overpressure bypass
valve are provided. Mount the shut-off valves on the space heating water inlets
and space heating water outlets. To ensure the minimum flow rate (and prevent
overpressure), install the overpressure bypass valve on the space heating water
outlet for the additional zone.
NOTICE
This unit is designed for operation on 2 temperature zones:
▪
underfloor heating in the main zone, this is the zone with the lowest water
temperature,

temperature.
1 Install the shut-off valves on the space heating water pipes.
