Preparation of the refrigerant pipe
Prepare the pipe in steps. Unsuitably made joints are one of the main reasons for leakage, the joints
must thus be made thoroughly and in accordance with the listed steps.
STEP 1: Cutting the pipe
• Use a pipe cutter which does not produce chips to cut the pipe.
• Determine the distance between the outdoor and indoor unit.
• Cut the pipes longer in order to ensure connecting the internal and external device normally.
STEP 2: Removal of chips
• Remove all chips from the part where the pipe was cut.
• Hold the pipe downward during cleaning so that the chips do not fall into the pipe.
