9.4.1 Check the water circuit
9.4 Water piping
All piping lengths and distances have been taken into consideration.
Requirements
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).
NOTE
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.
NOTE
The unit is equipped with a water inlet and water outlet for connection to a water circuit. This circuit must be provided by a
licensed technician and must comply with local laws and regulations.
The unit is only to be used in a closed water system. Application in an open water circuit can lead to excessive corrosion
of the water piping.
