CAUTION
• Bind the auxiliary pipes (two) and connecting
cable with facing tape tightly. In case of leftward
piping and rear-leftward piping, bind the auxiliary
pipes (two) only with facing tape.
Auxiliary pipes
Installation plate
• Carefully arrange pipes so that any pipe does not
stick out of the rear plate of the indoor unit.
• Carefully connect the auxiliary pipes and
connecting pipes to each other and cut off the
insulating tape wound on the connecting pipe to
avoid double-taping at the joint, moreover, seal
the joint with the vinyl tape, etc.
• Since dewing results in a machine trouble, make
sure to insulate both the connecting pipes. (Use
polyethylene foam as insulating material.)
• When bending a pipe, carefully do it, not to crush it.

unit. Improper drainage can result in dew-dropping.
This air conditioner has the structure designed to drain
water collected from dew, which forms on the back of
the indoor unit, to the drain pan.
Therefore, do not store the power cord and other parts
at a height above the drain guide.
