The amount of refrigerant put into the outdoor unit at the factory is sufficient to fill up to 20 m of refrigerant piping work. If the length of the refrigerant piping work is 20 m or less, addition of refrigerant at the installation site is unnecessary. If the length of the piping work exceeds 20 m, extra refrigerant must be added. Refer to the outdoor installation manual for details of the extra amounts. Overcharge or undercharge of refrigerant in the outdoor unit may cause malfunction of the compressor. Add Only R410A Refrigerant to These Units ­ 39 ­ 9-8-3. Provide heat insulation on the refrigerant piping on both the liquid side and gas side separately, and ensure that all joints in the insulation are completely sealed (without gap). Since the temperature of the piping on the gas side increases during heating operations, the heat insulating material used must be able to withstand temperatures of more than 120°C. Use the pipe insulation supplied in the accessory pack to insulate the piping connecting section on the indoor unit side. Packed valve handling precautions · Open the valve stem all the way out; do not try to open it beyond the stopper. 9-9-2 NOTE : Connect the earth line to the metallic part (i mark) located at the side of 3P terminal. Connect the wires between the units correctly. Errors made in the connections can result in the unit malfunctioning. Connect the control wires between the outdoor unit and indoor unit as shown in the figure below: 9-9-4.

Remove the Terminal cover and the Cord clamp. Insert the connecting cable into the pipe hole on the wall. Insert the connecting cable fully into the terminal block and secure it tightly with the screw. Tightening Torque: 1. 2 N·m (0. 12 kgf·m) 4. Fix the connecting cable by the Cord clamp with two screws. [. . . ] 14) Take off nut fixing the compressor on the bottom plate. (3 pcs. ) 15) Pull the compressor toward you.
