INSTALLATION INSTRUCTIONS
Step 4: Connect pipes
When connecting refrigerant pipes, be careful not to use excessive torque or
to deform the piping in any way. Connect the low pressure pipe fi rst and then
connect the high pressure pipe.
Note: When bending connective refrigerant piping, the minimum bending radi-
us is 10 cm (3.9 in).
CONNECTING PIPING TO INDOOR UNIT
1. Align the center of the two pipes that will be connected.
2. Tighten the fl are nut as tightly as possible by hand.
3. Using a spanner, grip the nut on the unit tubing.
4. While fi rmly gripping the nut on the unit tubing, use a torque wrench to tighten the fl are nut according
to the torque values in the torque requirements table below. Loosen the fl aring nut slightly, then tighten
again.
