7.5 - NOTES ON DRILLING HOLE IN WALL
It is necessary to drill a hole into the wall for the passage of the refrigerant piping
and of the signal cable between the internal and external units.
1. Determine the position of the hole in the wall based on the position of the external
unit.
2. Drill a hole in the wall of at least 65mm.
When drilling the wall hole, make sure to avoid wires, plumbing, and
other sensitive components.
3. Protect the hole edges to preserve the tubes and the cables.

7.6 - REFRIGERANT PIPING CONNECTION
When connecting refrigerant piping, do not let substances or gases other than the specified refrigerant enter
the unit.
The presence of other gases or substances will lower the unit's capacity, and can cause abnormally high
pressure in the refrigeration cycle.
This can cause explosion and injury.
• The branching pipe must be installed horizontally. An angle of more than 10° may cause
malfunction.
• DO NOT install the connecting pipe until both indoor and outdoor units have been installed.
• Insulate both the gas and liquid piping to prevent water leakage.
7.6.1 - Step 1: Cut pipes
When preparing refrigerant pipes, take extra care to cut and flare them properly. This will ensure efficient
operation and minimize the need for future maintenance.
1. Measure the distance between the indoor and outdoor units.
2. Cut the piping sections abounding by approximately 3÷4 cm on the length.
Use a wheel pipe cutter only to cut the pipes clamping it in short lengths so as not
to crush the pipe.
NEVER USE A NORMAL HANDSAW, scraps could fall inside the pipe and enter the circuitry
of the system, damaging the parts severely.
