2-8. DRAIN PIPING
• If the extension drain hose has to pass through a room, be sure to wrap it with commercially sold insulation.
• Thedrainhoseshouldpointdownwardforeasydrainow.(Fig.1)
• If the drain hose provided with the indoor unit is too short, connect it with drain hose (I) that should be provided at your site. (Fig. 2)
• When connecting the drain hose to the hard vinyl chloride pipe, be sure to insert it securely into the pipe. (Fig. 3)
• When routing the drain piping, make sure that the drain hose (1) is routed as shown. (Fig. 4)
• Insert the drain hose all the way to the base of the drain pan (end connection). (Fig. 5)

2-7. PIPE FORMING AND INSTALLATION
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gure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 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.
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.)
Felt tape (11)
Start wrapping the piping tape (G)
around the pipes and hose 10 mm
inside the indoor unit.
Fasten the end of the felt tape (11) with
a bandage stopper.
Make sure that the drain hose
is not routed upward.
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 in
-
door unit as shown below.
Smooth the cut edges of the side panels so that they will not damage
the insulation coating.

Cut the lower side panels to match the
height of the molding.
