Installation Layout Principles

Layout principles for installing the NetCol5000-A are as follows:

• If the outdoor unit is placed higher than the indoor unit, the vertical distance between them should be less than or equal to 30 m. An oil trap should be installed every 5 m to 6 m in the vertical direction along the gas pipe and an inverted trap for the inlet and outlet of the outdoor unit to ensure system reliability.
• If the indoor unit is placed higher than the outdoor unit, the vertical distance between them should be less than or equal to 8 m.
  • When calculating the height difference, the compressor base is regarded as the baseline for the indoor unit, and the condenser top is regarded as the baseline for the outdoor unit.
  • The inverted trap should be higher than the top copper pipe of the condenser.
  • In the figure, is a sign of a tilt, indicating that the scale of the pipe tilting is at least 1:200. The pipe tilting direction should be consistent with the hypotenuse of the right triangle.
  • If the indoor unit is placed lower than the outdoor unit, add an inverted U-shaped trap.
  • When pipes are routed through the wall or floor of the main equipment room, protective tubes should be installed. Sealing measures should be taken between the pipes and protective tubes (firestop putty recommended).
