NOTE
If the pipe is bent incorrectly, the indoor unit may unstably be set on the wall.
After passing the connecting pipe through the pipe hole, connect the
connecting pipes to the auxiliary pipes and wrap the facing tape around them.
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 one
•
another 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
•
connecting pipes. (Use polyethylene foam as insulating material.)
When bending a pipe, carefully do it, not to crush it.
