Purging the Unit From factory the unit is supplied and set with a pre-charge of nitrogen gas (insert gas). Therefore, all insert gas must be purged before connecting the assembly piping. Unscrew the pinch pipe at the end of each refrigerant pipe. Result: All inert gas escapes from the indoor unit. -
Page 11: Connecting The Refrigerant Pipe
Connecting the Refrigerant Pipe There are two refrigerant pipes of differing diameters: A smaller one for the liquid refrigerant A larger one for the gas refrigerant The inside of copper pipe must be clean & has no dust. Before connecting the reprigerant pipe, open the cover side. Refrigerant oil Remove the pinch pipe on the pipes and connect the assembly pipes to each pipe, tightening the nuts, first manually and then with a torque... -
Page 12: Cutting/Flaring The Pipes
Cutting/Flaring the Pipes Make sure that you prepared the required tools. (pipe cutter, reamer, flaring tool and pipe holder) If you want to shorten the pipe, cut it using a pipe cutter ensuring that the cut edge remains at 90° with the side of the pipe. There are some examples of correctly and incorrectly cut edges below. -
Page 13: Performing Leak Test & Insulation
Performing Leak Test & Insulation Leak test 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 responsible of installer to pressurize the whole system with nitrogen (using a pressure regulator) at a pressure above 4.1MPa(594.7 psig) (gauge). - Page 14 Performing Leak Test & Insulation Select the insulation of the refrigerant pipe. Insulate the gas side and liquid side pipe referring to the thickness according to the pipe size. Indoor temperature of 30°C(86°F) and humidity of 85% is the standard condition.
