WARNING Control box Remove the screw for the control box cover Remove the gas and liquid service port caps • Do not turn on the system! This is necessary for better vacuum operation (full OPEN position of Electronic Expansion Valve). 2 Connect the charging hose of the low pressure side of manifold gauge to a gas service port as seen in the picture. For connecting the refrigerant pipes 3 15 minutes Valve Gas service port <Low pressure> 4 Vacuum Pump (Backward flowing prevention) Liquid service port <Low pressure> 5 Liquid service port <High pressure> Connect the gas and liquid refrigerant pipes Step 3.3 Evacuating the air Installation The outdoor unit is loaded with sufficient R-410A refrigerant. Do not vent R-410A into atmosphere: it is a fluorinated greenhouse gas, covered by Kyoto Protocol, with a Global Warming Potential (GWP) = 2088. You should evacuate the air in the indoor unit and in the pipe. If air remains in the refrigerant pipes, it affects the compressor. It may cause reduction of cooling capacity and malfunction. Use a vacuum pump. CAUTION • When 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 stop valve open, the pipe inhales the air and it makes the pressure inside of the refrigerant cycle abnormally high. It may cause explosion and injury. Liquid service port <High pressure> 3 Open the valve of the low pressure side of manifold gauge anticlockwise. 4 Evacuate the air in the connected pipes using the vacuum pump for about 15 minutes. • Make sure that pressure gauge shows -0.1 MPa (-76 cmHg, 5 torr) after about 10 minutes. This procedure is very important to avoid a gas leak. • Close the valve of the low pressure side of manifold gauge clockwise. • Turn off the vacuum pump. • Check for 2 minutes if there is any pressure change. • Remove the hose of the low pressure side of manifold gauge. 5 Set a valve cork of liquid and gas service port to the open position. 18 English A3050 EE Better IM_DB68-06139A-00_EN_A5.indd 18 2016/5/6 10:32:06 Step 3.4 Adding refrigerant If you use a pipe longer than the length specified in the piping codes and standards, you must add 15g of refrigerant R-410A for each extra metre. If you use a pipe shorter than the length specified in the piping codes and standards, the evacuating time is normal. Refer to the Service Manual for further details. CAUTION • The remaining air in the Refrigeration cycle, which contains moisture, may cause malfunction of the compressor. • Always contact the service centre or a professional installation agency for product installation. R-410A is a mixed type of refrigerant. It is necessary for recharging under conditions of liquid.
