• 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.
