• To prevent condensation from dripping, put felt tape over the insulation materials
on the refrigerant and drain pipes within the unit as shown in the diagram.
C
• Arrange the drain hose so that it goes to the bottom of the unit.
• The overlapping width of felt tape is one half of the tape width.

F Take care that the middle of the drain hose is not raised.
G In the case of left piping, the refrigerant pipes and the drain pipe should be taped separately.
H Wrap together the refrigerant pipes and the drain pipe with felt tape so that white felt over-
laps by 25/32 in. (20 mm) or more.
* The pipes should be wrapped so that they are housed behind the unit.
I Fix the end of the felt tape with a bandage fixture.

Using the unit's pipe storage space (for left and left rear piping)
• To prevent cooling pipes from gathering moisture, wrap the pipes that are in the
unit's pipe storage space with the felt tape provided.
• When wrapping with the felt tape, be sure to double over by no more than half the
width of the tape.
• Use a bandage clip etc to fasten the end to the felt tape.
