Place the pattern sheet on the ceiling at the spot where you want to install the indoor unit. • Since the diagram is made of paper, it may shrink or stretch slightly due to temperature or humidity.
Page 10: Purging The Unit
Purging the Unit On delivery, the indoor unit is loaded with inert gas. All this gas must therefore be purged before connecting the assembly piping. To purge the inert gas, proceed as follows. Unscrew the pinch pipe at the end of each refrigerant pipe. Wet cloth Result : All inert gas escapes from the indoor unit.
Page 11: Cutting/Flaring The Pipes
Cutting/Flaring the Pipes 1. Make sure that you prepared the required tools. (pipe cutter, reamer, flaring tool and pipe holder) 2. 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.
Page 12: 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 responsibility of installer to pressurize the Leak check whole system with nitrogen (using a pressure regulator) at a pressure above 4.1 MPa(594.7 psig) (gauge).
Page 13 5. 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. If the pipe is installed in a high humidity condition, use one grade thicker insulation by referring to the table below.
Page 14 Performing leak test & insulation Refrigerant pipe before EEV kit and MCU or without EEV kit and MCU You can contact the gas side and liquid side pipes but the pipes should not be pressed. Insulation When contacting the gas side and gas side pipe, use 1 grade thicker Insulation insulation.
