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. 1 Leave the system in the standby mode. WARNING Remove the gas and liquid service port caps For connecting the refrigerant pipes • 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. Gas service port <Low pressure> 3 Liquid service port <High pressure> Connect the gas and liquid refrigerant pipes Valve 15 minutes 4 Vacuum Pump (Backward flowing prevention) 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. Liquid service port <Low pressure> 5 Liquid service port <High pressure> 46 English DB68-06039A-00.indd 46 5/25/2016 7:08:57 PM 3 Open the valve of the low pressure side of manifold gauge anticlockwise. Siphon 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. Charge the refrigerant standing the cylinder upright. Charge the refrigerant turning the cylinder upside down. <Cylinder with siphon> <Cylinder without siphon> NOTE • If R-410A refrigerant is charged with gas, the composition of the charged refrigerant changes and the characteristics of the equipment vary. • During the measuring operation of refrigerant quantity added use electronic scales. If cylinder doesn't have siphon, upset it. Step 3.4 Adding refrigerant If you use a pipe longer than the length specified in the piping codes and standards, you must add 15 g of refrigerant R-410A for each extra meter. 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 on the compressor. • Always contact the service centre or a professional installation agency for product installation. Installation R-410A is a mixed type of refrigerant. It is necessary for recharging under conditions of liquid. When recharging refrigerant from the refrigerant cylinder to the equipment. Before recharging, check whether the cylinder has a siphon or not. There are two ways to recharge the refrigerant: English 47 DB68-06039A-00.indd 47 5/25/2016 7:08:57 PM Installation Inspection Test parts for the indoor unit Step 4.1 Performing the gas leak tests 1 Before inspecting the leakage, use a torque wrench to close the cap for the stop valve.
