2.9.1 - 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.
3. Make sure that the pipe is cut at a perfect 90°
angle.
DO NOT DEFORM PIPE WHILE CUTTING.
Be extra careful not to damage, dent, or
deform the pipe while cutting. This will
drastically reduce the heating efficiency
of the unit.
2.9.2 - Step 2: Remove burrs
Burrs can affect the air-tight seal of refrigerant piping
connection. They must be completely removed.
1. Hold the pipe at a downward angle to prevent
burrs from falling into the pipe.
2. Using a reamer or deburring tool, remove all burrs
from the cut section of the pipe.
2.9.3 - Step 3: Flare pipe ends
Proper flaring is essential to achieve an airtight seal.
1. After removing burrs from cut pipe, seal the ends
with PVC tape to prevent foreign materials from
entering the pipe.
2. Sheath the pipe with insulating material.
3. Place flare nuts on both ends of pipe. Make sure
they are facing in the right direction, because you
can't put them on or change their direction after
flaring.
