Anleitung Zusammenfassung
It may cause reduction of cooling capacity and malfunction. Refrigerant for air purging is not charged in the outdoor unit. Use Vacuum Pump as seen in the picture. • 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 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 injury. 1. Connect each assembly pipe to the appropriate valve on the outdoor unit and tighten the flare nut. 2. Tighten the flare nut first with your hands, and then with a torque wrench, applying the following torque: Outdoor unit Indoor unit Gas pipe side Liquid pipe side • Excessive torque can be cause of gas leakage. Outer Diameter Torque (kgf•cm) o6.35 mm 140~170 o9.52 mm 250~280 o12.70 mm 380~420 o15.88 mm 440~480 o19.05 mm 990~1210 o22.23 mm 990~1210 • Make the electrical connection and leave the system into “stand by mode”. Do not turn on the system! This is necessary for better vacuum operation (full OPEN position of Electronic Expansion Valve - EEV -). 3. Connect the charging hose of the low-pressure side of manifold gauge to a gas service port as seen in the picture. 4. Open the valve of the low pressure side of manifold gauge counterclockwise. 5. Purge the air in the connected pipes using the vacuum pump for about 15 minutes. . Make sure that pressure gauge shows -0.1MPa(-76cmHg) 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. 6. Set a valve cork of liquid and gas service port to the open position. 7. Mount the valve stem nuts and the service port cap to the valve, and tighten them at the torque of 183kgf•cm with a torque wrench. 8. Check for a gas leak paying particular attention to the 3-way valve’s stem nuts and to the service port cap (Refer to page 37). Manifold gauge Valve Gas service port Vacuum Pump Liquid service port (Backward flowing prevention) Valve stem Stem nut A (Gas) B (liquid) Adding Refrigerant Add refrigerant charge according to table below: If you use a pipe longer than 5m, ‘A’g of refrigerant R410A must be added for each extra meter. If you use a pipe shorter than 5m, The purge time is normal. Refer to the Service Manual for further details.

Purging the connected pipes Important information regulation regarding the refrigerant used Refrigerant type GWP value R410A 1975 This product contains fluorinated greenhouse gases covered by the Kyoto Protocol. Do not vent gases into the atmosphere. 1.

Charging the refrigerant under conditions of liquid by using a liquid pipe R410A 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, follow the instructions below. 1. Before recharging, check whether the cylinder has a siphon or not. There are two ways to recharge the refrigerant. Cylinder with siphon Cylinder without siphon siphon . Charge the refrigerant standing the cylinder upright. . Charge the refrigerant turning the cylinder upside down. • If R410A 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 an electronic balance. If cylinder doesn’t have syphon, upset it. Performing the gas leak tests Make sure to check for gas leaks before completing the installation process (connecting the assembly pipe and hose between indoor unit and outdoor unit, insulating t...
