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.
CAUTION
Also avoid areas where electrical wiring or conduits are
located.
The above precautions are also applicable if tubing goes
through the wall in any other location.
(1) Using a sabre saw, keyhole saw or hole-cutting drill
attachment, cut a hole in the wall.

3-5. 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 1-1/4” nut for both water inlet and outlet connection
and clean all pipings with tap water before connecting to the
indoor unit.
●
Cover the piping 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 an existing tank is to be connected to this indoor/outdoor
unit, ensure the pipings are clean before water piping
installation is carried out.
●
An external filter (30 mesh or more, field supplied) must
be installed before the water inlet of the indoor unit (with
“WATER IN” indication).
●Water operating temperatures (Minimum ~ Maximum) : 5 °C
~ 65 °C
●Water operating pressures (Minimum ~ Maximum) : 0.05 MPa
~ 0.3 MPa
