Do not use the refrigerant in the outdoor unit. For details, see the manual of the vacuum pump. <Using a vacuum pump> Be sure to use a vacuum pump with counter-flow prevention function so that inside oil of the pump does not flow backward into pipes of the air conditioner when the pump stops. (If oil inside of the vacuum pump enters into the air conditioner, which use R410A, refrigeration cycle trouble may result. ) 1. Connect the charge hose from the manifold valve to the service port of the gas side packed valve. Connect the charge hose to the port of the vacuum pump. · Securely tighten the valve stem cap with torque in the following table: Gas side (12. 70 mm) Liquid side (6. 35 mm) Service port 50 to 62 N·m (5. 0 to 6. 2 kgf·m) 16 to 18 N·m (1. 6 to 1. 8 kgf·m) 9 to 10 N·m (0. 9 to 1. 0 kgf·m) L N 1 2 3 Terminal screw Cord clamp Earth line Screw Cord clamp Hexagonal wrench is required. 4m m Power supply cord Connecting cable LN 10 12 3 10 10 70 70 10 80 60 Fig. 8-5-7 Power supply cord Earth line Connecting cable Fig. 8-5-8 Model Power s ource Maximum running current Plug s o c k e t & f u s e r a t i n g Power cord 24 Class 18 Class 50 Hz, 220 240 V Single phase 18A 20A 16A 20A 2 4 mm (H07R N-F or 245 IE C 66) or 3. 5 mm2 (AWG -12) CAUTION · Wrong wiring connection may cause some electrical parts burn out. · Be sure to comply with local codes on running the wire from indoor unit to outdoor unit (size of wire and wiring method etc). · Every wire must be connected firmly.

How to Set Remote Control Selector Switch When two indoor units as installed in seperated rooms, there is no need to change the selector switch. <Remote control selector switch> · When two indoor units are installed in the same room or the adjacent two rooms, they may be controlled simultaneously with a single remote control. To prevent this, set either unit and its remote control to B setting. (Both units are set to A setting before shipment. ) · The remote control signal is not recived when the indoor unit setting is different from the remote control one. Set the remote control selector switch with the remote control [B] is indicated on the liquid crystal display when setting remote control selector switch to B.
