Pipe Connection Steps
CAUTION
Bend and arrange pipes carefully without
damaging the pipes and their insulating
layers.
Do not let the interface of the indoor unit
bear the weight of the connecting pipe;
otherwise, the connecting pipe may be
crushed and deformed, which will affect
the cooling (heating) effect, or the thermal
insulation materials may be compressed,
resulting in air leakage and condensation.
The connecting pipes to the outdoor units. Please refer the Installation and Operation Manual of the outdoor units.
