Note: Refer to 4. FLARE CONNECTION, PIPE CONNECTION.
Pipe Forming
• Route the drain hose diagonally below the connecting pipes.
• Make sure that the drain hose is not routed upward and that there are no
waves in the hose.
• Do not pull the hose when applying the tape.
• Route the piping so that it does not project past the rear of the indoor unit.
(Refer to the figure to the right.)
Connecting Pipe Installation
• Install the connecting pipes so that the piping can move slightly to the
front, back, left, and right.
• Be sure to insulate the connecting pipes so that they do not contact the
panel.
• Be careful not to crush the connecting pipes when bending them.
(Use a tube benders for left or right piping.)
• The pipe cover cannot be attached without connecting the conduit pipe
after connecting the pipes.
FOR LEFT OR LEFT-REAR PIPING
Bundle the connecting pipes and drain hose together, and then wrap them in
felt tape (11).
Cut and use the lower side panels on the left and right sides of the indoor unit
as shown below.
Smooth the cut edges of the side panels so that they will not damage the insula-
tion coating.
• For left or right piping
• Installing flush against a wall with molding
Wrap the felt tape (11) tightly around the pipes and hose starting near where
the pipes and hose are routed from the indoor unit. (The overlap width of the
felt tape (11) should not be more than 1/2 of the tape width.)
