11.3.1. HOW TO FIX INSTALLATION PLATE
The mounting wall is strong and solid enough to prevent it from
the vibration.
The centre of installation plate should be at more than 452 mm
at right and left of the wall.
The distance from installation plate edge to ground should
more than 1300 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 3 sets of plug,
bolt and washer (all non-supply) with size M8.
11.3.2. TO DRILL A HOLE IN THE WALL
AND INSTALL
PIPING
1. Insert the piping sleeve to the hole.
2. Fix the bushing to the sleeve.
3. Cut the sleeve until it extrudes about 15 mm from the
wall.
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.

11.3.3.2. Water Piping Installation
• Water inlet and water outlet on 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.
• Do not install any valve between indoor unit and water piping
to avoid accidental closure of water supply to the indoor unit.
• Use 3/4" nut for both water inlet and outlet connection and
clean all tubes 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.
• Connect water inlet connector of indoor unit (indicate with
"IN") to boiler tank outlet. Then, connect water outlet
connector of indoor unit (indicate with "OUT") to boiler tank
inlet. Fail to connect the tube appropriately might causing
the indoor unit malfunction.
• Be sure to use two spanners to tighten the connection.
Further tighten the nuts with torque wrench in specified
torque as stated in the table.
• If non-brass metallic piping is used for installation, make
sure to insulate the pipes to prevent galvanic corrosion.
• Make sure to insulate the water circuit pipes to prevent
reduction of heating capacity.
