Pipe Layout
Bend the pipes or punch holes in the wall as needed. The deformed pipe area must not exceed 15% of the total
area. A protective casing should be installed at the wall or floor hole. The weld joint must not be inside the
1
casing. The drill hole on the external wall must be sealed and tightly wrapped with a binding tie to prevent
impurities from entering the pipe. The pipe must be insulated with the correctly-sized insulation pipe.
Note: D1 is the minimum diameter, and D2 is the nominal diameter.
The wrapped connecting pipe is plugged through the wall hole sleeve from the outdoor side and enters the
2
indoor side. The pipes must be arranged carefully so as not to damage the piping.

Pipe Connection Steps
Measure the required length of the connecting pipe. Make the connecting pipe using the following method (see
"Pipe Connection" for details).
Connect the IDU first, then connect the ODU.
Before tightening the flare nut, apply refrigeration oil on the inner and outer surface of the pipe flare (you must
1
use refrigeration oil compatible with the refrigerant for this model), and tighten it 3 or 4 turns by hand. When
connecting or removing a pipe, use two wrenches at the same time.
[ Caution ]
Bend and arrange pipes carefully without damaging the pipes and their insulating layers.
Do not let the interface of the IDU 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.
