4-8 PIPING INSTALLATION
CONNECTING PIPE INSTALLATION
• Install the connecting pipes so that the piping can move slightly to the front, back, left, and right.
FOR RIGHT DOWNWARD PIPING
• Be sure to insulate the connecting pipes and place them near the rear of the indoor unit so that they do not
contact the front panel.
• Be careful not to crush the connecting pipes when bending them.
