Page 40: Refrigerant Connecting Piping Installation
Refrigerant Connecting Piping Installation Length and Level Difference Requirements for the Pipe Connections of IDU and ODU Different ODUs have different requirements for length and level differences for the piping. Refer to the Installation & Owner's Manual attached with the ODU. [ Warning ] During the installation of the connecting pipes, do not allow air, dust, and other debris to penetrate the piping system, and make sure the interior of the pipes is dry. - Page 41 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 use refrigeration oil compatible with the refrigerant for this model), and turn it 3 or 4 turns by hand to tighten it.

Page 45: Drainage Pipe Installation
Drainage Pipe Installation [ Caution ] Before installation of the condensate pipeline, determine its direction and elevation to avoid intersection with other pipelines to ensure that the slope is smooth and straight. The highest point of the drainage pipe should be equipped with a discharge port to ensure the smooth discharge of condensate water, and the discharge port must face downwards to prevent dirt from entering the pipe. - Page 46 The drainage pipes of the unit (especially the indoor part) must be evenly wrapped with thermal insulation pipes and fastened with cable ties to prevent air from entering and producing condensate water. Cable tie Drainage pipe Thermal insulation pipe To prevent water from flowing back into the air conditioner when it stops running, avoid installing the drainage pipe in a way that slopes upwards for a long distance.
- Page 47 The end of the drainage pipe must be more than 50mm above the ground or from the base of the water discharge slot. In addition, do not submerge it in water. To discharge the condensed water directly into a ditch, the water discharge pipe must bend upwards to form a U-shaped water plug to stop odors from entering the room via the water discharge pipe.
- Page 48 Water Discharge Test Before the test, make sure that the water discharge pipeline is smooth, and check that each connection is properly sealed. Conduct the water discharge test in a new room before the ceiling is plastered. Drainage pipe Test water outlet Master unit The drainage pipes for IDUs may use a PVC pipe Water cover...
