9.4 Water piping
All piping lengths and distances have been taken into consideration.
The maximum allowed thermistor cable length is 20m. This is the maximum
allowable distance between the domestic hot water tank and the unit (only for
installations with a domestic hot water tank).The thermistor cable supplied with
the domestic hot water tank is 10m in length.In order to optimize efficiency we
recommend installing the 3-way valve and the domestic hot water tank as close
as possible to the unit.
If the installation is equipped with a domestic hot water tank (field supply), please refer to the domestic hot water tank
Installation And Owner's Manual. If there is no glycol (anti-freeze) in the system there is a power supply or pump failure,
drain the system (as shown in the figure below).
If water is not removed from the system in freezing weather when unit is not used. The frozen water may damage the
water circle parts.
9.4.1 Check the water circuit
The units are equipped with a water inlet and outlet for connection to a water circuit.
The units should only be connected to closed water circuits. Connection to an open water circuit would lead to excessive
corrosion of the water piping. Only materials complying with all applicable legislation should be used.
