Step 4: Prepare refrigerant piping
The refrigerant piping is inside an insulating
sleeve attached to the back of the unit. You must
prepare the piping before passing it through the
hole in the wall.
UNIT IS ADJUSTABLE
Keep in mind that the hooks on the mounting
plate are smaller than the holes on the back
of the unit. If you find that you don t have ample
room to connect embedded pipes to the indoor
unit, the unit can be adjusted left or right by about
30-50mm (1.25-1.95in), depending on the model

4.1 Tools needed

-You will require the following tools to carry
out this installation work correctly:
1x open-ended spanner, 19 mm
1x open-ended spanner, 22 mm/24mm
1x open-ended spanner, 24 mm/27mm

4.2 Important information
Follow the detailed instructions for
connecting the refrigerant pipes to the
indoor unit and outdoor unit. We can only
provide a warranty if the lines are installed
correctly as described in the instructions.
Do not remove the sealing caps and
stoppers until immediately before you
install the lines.
To prevent leaks, ensure that the quick-
release screw connections are absolutely
free of dirt. Moisture or foreign bodies will
adversely affect the function of the quick-
release connectors, leading to a risk of
refrigerant loss (not covered by the
warranty).
Only install refrigerant lines outdoors in
dry weather.
The refrigerant lines must not be
installed and then plastered over.

(1.2-1.95in)
Remember that if they are tightened
with too little torque, they will leak, but
if they are tightened with too much
torque, the screw connections may
suffer damage. If you should not be
confident about connecting the
refrigerant line connectors yourself,
it is imperative that you contact your
customer service team or a
refrigeration contractor.
Important!
designed for one-time installation.
Their seal can not be guaranteed if
they are installed on more than one
occasion. This will also void the
warranty.
Please make sure that refrigerant is
never allowed to enter the environment.
Improper handling of refrigerant may
be harmful to health. Always wear work
gloves and goggles when handling
refrigerant.
Do not smoke during the installation
work. The equipment must never be
operated without the refrigerant lines
connected, otherwise the equipment
will be damaged immediately.
The screw connections may only be
tightened using the appropriate
open-ended spanner.
