11.3.1 How to Fix Installation Plate
The mounting wall is strong and solid enough to prevent
it from vibration.
The centre of installation plate should be at more than
551 mm at right and left of the wall.
The distance from installation plate edge to ground
should more than 1550 mm.
Always mount the installation plate horizontally by
aligning the marking thread and using a level gauge.
Mount the installation plate on the wall with 6 sets of
plug, bolt and washer (all non-supply) with size M8.

When the wall is hollow, please be sure to use the sleeve for
tube assembly to prevent dangers caused by mice biting the
connecting cable.
4 Finish by sealing the sleeve with putty or
caulking compound at the final stage.

1 When connecting solar pump station cable
between indoor unit and solar pump station, the
distance between both apparatuses shall be
2 ~ 8 meters and the length of the said cable
must be shorter than 10 meter. Fail to do so
may lead to abnormal operation to the system.
2 Engage the slots on the indoor unit to the hooks
of installation plate . Ensure the hooks are
properly seated on the installation plate by
moving it left and right.

installation plate, , as illustrated below.
11.3.3.2 Water Piping Installation
The minimum requirement of water in the system is
50 litres. If this value could not be achieved, please
install additional buffer tank (field supply).
Water inlet and water outlet in indoor unit are used
for connection to water circuit. Please request a
licensed technician to install this water circuit.
This water circuit must comply with all relevant
European and national regulations, i.e. IEC/EN
61770.
Be careful not to deform the piping with excessive
force when doing piping connection job.
Use Rp 1¼” nut for both water inlet and outlet
connection and clean all pipings with tap water
before install.
Cover the pipe end to prevent dirt and dust when
inserting it through a wall.
Choose proper sealer which can withstand the
pressures and temperatures of the system.
If existing tank is to be connected to this
indoor/outdoor unit, ensure the pipes are clean
before water pipe installation is carries out.
