    1.2. Locate The Pipe Drill a hole in the wall (suitable just for the size of the wall conduit), then set on the fittings such as the wall conduit and its cover. Bind the connecting pipe and the cables together tightly with binding tapes. Do not let air in, which will cause water leakage by condensation.
  • Page 29 in the pipe. At this time, it should be pumped 1 hour more.  If the pump can’t achieve -755mmHg after pumping 3 hours, please check if there are some leakage points.  Vacuum placement test: place 1 hour when it achieves -755mmHg, pass if the vacuum watch shows no rising.

  • Page 30: Additional Refrigerant Charge

    3.Additional Refrigerant Charge Caution ● Refrigerant cannot be charged until field wiring has been completed. ● Refrigerant may only be charged after performing the leak test and the vacuum pumping. ● When charging a system, care shall be taken that its maximum permissible charge is never exceeded, in view of the danger of liquid hammer.

  • Page 31: Water Drainage

    4.Water Drainage 4.1 Gradient and Supporting 4.1.1 Keep the drainpipe sloping downwards at a gradient of at least 1/100. Keep the drainpipe as short as possible and eliminate the air bubble. 4.1.2 The horizontal drainpipe should be short. When the pipe is too long, a prop stand must be installed to keep the gradient of 1/100 and prevent bending.
  • Page 32 Ceiling cassette 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.
