Page 21: Connecting Up And Removing Air In The Circuit
Connecting up and removing air in the circuit CAUTION • W hen installing, make sure there is no leakage. When recovering the refrigerant,ground the compressor first before removing the connection pipe. If the refrigerant pipe is not properly connected and the compressor works with the service valve open, the pipe inhales the air and it makes the pressure inside of the refrigerant cycle abnormally high, It may cause explosion and injur y. -
Page 22: Cutting/Flaring The Pipes
Connecting up and removing air in the circuit CAUTION • C onnect the indoor and outdoor units using pipes with flared connections (not supplied). For the lines, use insulated, unwelded, degreased and deoxidized copper pipe, (Cu DHP type to ISO 1337 or UNI EN 12735-1), s uitable for operating pressures of at least 4200kPa and for a burst pressure of at least 20700kPa. -
Page 23: Performing Leak Tests
Performing leak tests LEAK TEST WITH NITROGEN (before opening valves) In order to detect basic refrigerant leaks, before recreating the vacuum and recirculating the R-410A, it’s responsable of installer to pressurize the whole system with nitrogen (using a cylinder with pressure reducer) at a A(Gas) pressure above 2 bar, less than 40 bar (gauge). -
Page 24: Insulation
Insulation Once you have checked that there are no leaks in the system, you can insulate the piping and hose. To avoid condensation problems, place an insulator around each refrigerant pipe. NOTE • W hen insulate the pipe, be sure to overlap the insulation. • Y ou have to use more than 120°C insulation(T13.0 or thicker Acrylonitrile Butadien Rubber) for the gas refrigerant pipe. -

Using stop valve To Open the Stop Valve 1. Open the cap and turn the stop valve counterclockwise by using a hexagonal wrench. 2. Turn it until the axis is stopped. NOTE • D o not apply excessive force to the stop valve and always use special instruments. Otherwise, the stopping box can be damaged and the back sheet can leaks. • I f the watertight sheet leaks, turn the axis back by half, tighten the stopping box, then check the leakage again. If there is no leakage any more, tighten the axis entirely. -
