  • Page 34 Installation 1. Refrigerant pipe installation 1.1. Measure the necessary length of the connecting pipe, and make it by the following way. Connect the indoor unit at first, then the outdoor unit. Bend the tubing in proper way. Do not harm them. CAUTIONS: Daub the surfaces of the flare pipe and the joint nuts with frozen oil, and wrench it for 3~4 rounds With hands before fasten the flare nuts.
  • Page 35 Installation 2.2. Vacuum dry procedure There are two methods of vacuum dry due to different construction environment: common vacuum dry, special vacuum dry. . Common vacuum dry procedure Vacuum dry (for the first time)---connect the all-purpose detector to the inlet of liquid pipe and gas pipe, and run the vacuum pump more than two hours (the vacuum pump should be below -755mmHg) -755mmHg after pumping 2 hours, moisture or leakage point will still exist in the pipe.
  • Page 36 Installation entering and forming condensation water. . Vacuum dry for the second time······1h pumping Determinant: Pass if achieving below -755mmHg. If - . Vacuum placing test ······ 1h . Sketch map of special vacuum dry procedure 3. Additional charge 3.1. When the length of the one-way pipe is less than 5m, additional refrigerant charge after vacuuming is unnecessary.
  • Page 37 Installation 4.1.3. Precautions The diameter of drainpipe should meet the drainage requirement at least. The drainpipe should be heat-insulated to prevent atomization. Drainpipe should be installed before installing indoor unit. After powering on, there is some water in water-receiver plate. Please check if the drain pump can operate correctly. All connection should be firm.
  • Page 38 Installation 4.4 Convergent drainage 4.4.1. The number of indoor units should be as small as possible to prevent the traverse main pipe overlong. 4.4.2. Indoor unit with drain pump and indoor unit without drain pump should be in different drainage system. 4.4.3.
  • Page 39 Installation 5. Insulation work 5.1 Insulation material and thickness 5.1.1. Insulation material in the high-pressure side, no less than 120 in the low-pressure side(For the cooling type machine, no requirements at the low-pressure side.) Example: Heat pump type----Heat-resistant Polyethylene foam (withstand above 120 ) Cooling only type---- Polyethylene foam (withstand above 100 ) 5.1.2.
  • Page 40 Installation wrong right Gas pipe and liquid pipe Insulate the gas pipe Insulate the gas pipe and should (cooling only) liquid pipe For construction convenience, before laying pipes, use insulation material to insulate the pipes to be deal with, at the same time, at two ends of the pipe, remain some length not to be insulated, in order to be welded and check the leakage after laying the pipes.
