Page 36: 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 37 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 38 Nitrogen displacement When brazing pipes, fill the pipes with nitrogen. First evenly heat the inner pipes, then the outer pipes, and fill the joints with welding material. Warning When it is necessary to fill the piping with nitrogen during welding, the pressure must be kept at 0.02MPa using a pressure relief valve.

Page 41: 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 42 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, the drainage pipe should be inclined downward to the outdoor side (drainage side), with a downward slope of 1/100 or more.
- Page 43 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 44 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. The drainage pipe can be made of PVC pipe (outer diameter: 25mm). Based on the actual installation circumstances, users can purchase pipes of appropriate lengths from a sales agent or the local after-sales service center, or purchase them directly from the market.

Page 45: Electrical Connection
Electrical Connection Danger The power supply must be cut off before any electrical work is carried out. Do not conduct electrical work when the power is on; otherwise, it may cause serious personal injury. The air conditioning unit must be grounded reliably and must meet the requirements of the local country/region. If the grounding is not reliable, serious personal injury due to electric leakage may occur. - Page 46 Electrical Characteristics Electric specifications of the IDU Unit power Frequency Voltage (kW) power input (Hz) 0.46 0.37 0.46 0.37 0.54 0.43 220~240 0.54 0.43 0.61 0.49 0.65 0.52 0.81 0.65 Notes: MCA: Min.

- Page 49 ② Power cable system connection Power cable system connection depends on the forms of communication between the IDU and ODU. For the HyperLink communication form with an independent power supply, IDUs are allowed to have an independent power supply. For other communication forms, IDUs should be provided with uniform power supply.
- Page 50 IDUs are provided with uniform power supply*, which are wired as follows: 1. HyperLink communication with the uniform power supply: Power supply for IDU L1+La+Ln ≤ 2000m Wire diameter: 0.75mm Communication wire × × Circuit breaker Power cable Distribution box Distribution box Master ODU IDU 1#...
- Page 51 Caution When the IDUs are provided with a uniform power supply, if the IDUs in the same refrigerant system are SDV6 IDUs, thenIDUs and ODU can communicate either via HyperLink with a uniform power supply, or via P/Q communication. If someof the IDUs in the same refrigerant system are non-SDV6 series, then IDUs and ODU can only communicate via P/Q orP/Q/E communication.
- Page 52 Communication line connection ① Selection of communication method for IDUs Equipped with independently developed HyperLink (M1M2) communication, SDV6 series IDUs also preserve the previousRS-485 (PQE) communication method. They are compatible with non-SDV6 IDUs. Pay attention to the type of IDU you havepurchased before connecting communication lines.
- Page 53 Caution Please select the communication line according to the requirements in the above reference table. Use shielded cables for communication when strong magnetism or interference is present. On-site wiring must comply with the relevant regulations of the local country/region and must be completed by professionals.
- Page 54 ③ IDU and ODU communication HyperLink communication (with independent power supply) Single unit: HyperLink communication is a new type of IDU and ODU communication technology.
