Elements to be removed
• Bend pipes with maximum bending radius (at
least R100~R150). Do not bend pipes many
times. Use a bending machine.
• Connection of refrigerant pipes to the outdoor unit
and indoor unit should be perform with flare con-
nections after prior dismantling of production ends.
• Connect the socket connection and tighten with
appropriate torque. Apply the appropriate tight-
ening angle if the torque wrench is not available.
