Water connections
When making water connections, take into consideration remarks below:
 Heat pump is determined to be connected to a closed system of central heating. In order to
guarantee fault-free operation, central heating installation must be made by authorized specialized
persons and in accordance with corresponding standards and rules.
 Try to reduce water resistance in the piping.
 Piping must be clean and without any dirt and obstructions. It is necessary to make a leak test and
check that there is no water leaking.
 Piping pressure test must be done separately. DO NOT MAKE the test, when the heat pump is
connected.
 There is a flow switch mounted inside the heat pump. Ensure correct connection of this switch and
its function and its control by control unit.
 It is better to make the connection between the heat pump and the building as a flexible connection,
so that transfer of vibrations is eliminated. Water piping holders must be made independently and
must not use the unit of heat pump.
 Try to prevent air presence in a water piping and mount venting valve to the upper part of water
distribution system.
 For easy inspection during the operation, it is necessary to install temperature and pressure gauge
to the water input and output.
 Lower parts of water distribution system must be equipped with a drain outlet and a drain outlet is
already mounted on the heat pump frame. If heat pump is not running, then it is necessary to drain
the water from the system in winter time. For water distribution system venting, a venting valve must
be mounted on the upper side of the system. For easy maintenance, it is not necessary to make an
insulation on the drain part and venting valve. Drain parts and venting valve are not parts delivered
with the heat pump; these parts must be supplied by an installation company.
Caution!
Danger of equipment and system damage due to the use of water with high
content of calcium and magnesium!
