2.2 Tools needed
2.3 Installation of the indoor control unit
Most people already have the tools needed for
installation: spirit level, pencil, crosshead
screwdriver, drill, 8 mm. concrete drill bit, detection
drill, square, tape measure or ruler, tape width 65
mm, hole saw about 80 mm (deviation in size may
occur), knife and two adjustable spanners or pliers
(and possibly torque wrench).
2.3.1 Installation notes
1)
2) The indoor unit shall be placed in dry and well-ventilated environment.
3) Indoor unit mustn't be installed in an environment where volatile, corrosive or flammable liquid
or gas exists.
4)
The indoor control unit should be installed indoors and mounted on the wall, with water outlet
downwards.

Please choose a suitable position to install the indoor control unit as follows:
Enough space should be left around the indoor unit for futher maintenance.

2.3.2 Installation
Indoor unit should be mounted on the wall as per procedures below:
1) Take out the expansion bolts and mounting board from accessory and put the mounting board on the
wall horizontally; Mark on the wall the location for bolts through the holes on mounting board.
2) Drill holes with proper diameter for expansion bolts.
3)
4)
5)
6) Hang the indoor unit onto the mounting board and make sure it's placed well before you let go
your hands. The installation is finished.
control
Unscrew the nuts out from the expansion bolts.
Fix the mounting board on the expansion bolts a little bit, but don't be too tight.
Use a hammer to pound the expansion bolts into the drilled holes. Fasten the nuts by turning the wrench
to fix the mounting board on the wall.

Note:
You must choose very firm wall for installation otherwise the bolts may get loose and unit be damaged!
If it's wood wall, please use self-tapping screws in accessory instead of bolts. Please hang
the mounting board directly onto the wood wall without drilling holes. The wood wall must be firm
enough. Wood walls that are too thin, too brittle or humid are not adequate for installation.

2.4 Installation of the monoblock unit
2.4.1 Installation notes
1) The monoblock unit can be located in a open space, corridor, balcony, and roof.
2) The unit shall be placed in dry and well-ventilated environment;
3) unit mustn't be installed in an environment where volatile, corrosive or flammable liquid or
gas exists.
4) Please don't install unit close to bedroom or living room, because there is some noise when
it's running.
5) When installing the unit in harsh climatic conditions, sub-zero temperatures, snow, humidity..., please
raise the unit above the ground by about 50cm.
6) Please ensure there is drainage system around the location, to drain the condensate water under
defrosting mode.
7) When installing the unit, tilt it by lcm/m for rain water evacuation.
8)
9) Please don't install the indoor control unit and unit in damp locations, otherwise it may
cause short-circuit or corrosion of some components. The unit should be free from corrosive and
moisture surrounding. Otherwise the lifetime of the unit might be shortened.
10) Please ensure enough space around the unit, for better ventilation and maintenance.
Please refer to the illustration below.

If the unit is
installed in humid environment, electronic components may get corroded, or short-circuited because of
heavy humidity.
It's recommended to install an awning above the unit, to protect the snow from clogging in
the air inlet and outlet and ensure the normal running.
Install unit far away from the exhaust port of kitchen, to avoid oil smoke entering
into unit and adhering to heat exchanger. It's hard to clean up.

2.4.2 Installation
User can either use the dedicated mounting bracket from the supplier, or prepare a suitable bracket for the
unit installation. Make sure the installation meets following requirements:
1) The unit must be installed on flat concrete blocks, or a dedicated mounting bracket. The bracket should
be able to support at least 5 times of unit’s weight.
2) All nuts must be tightened after the bracket is fixed; otherwise, it may cause damage to the equipment.
3) User should double check and make sure the installation of unit is firm enough.
4) The bracket can be of stainless steel, galvanized steel, aluminum and other materials as required by the
user.
5) Besides the mounting bracket, the user can also install the monoblock unit on two concrete blocks, or a
raised concrete platform. Please make sure that the unit is securely fastened after installation.
6) Please see the dimensions of unit when choose a suitable wall bracket. monoblock
