(1) Install the drain piping.
01_EN_3PN09042-1A.fm Page 8 Friday, March 21, 2008 7:21 PM 1. Remove the control box lid. Connect the remote controller and power supply (single-phase, 50 Hz 220-240 V or single-phase, 60Hz 220V) respectively to the terminal block and securely connect the earth also (as shown in the figure below). (1) Install the drain piping. Drain socket CAUTION Securely clamp the cables with the clamps (9)(10) offered as accessories as shown in Fig. 17 so that tension will not be applied on the cable connection areas.
01_EN_3PN09042-1A.fm Page 9 Friday, March 21, 2008 7:21 PM 〈 PRECAUTIONS 〉 Drain piping connections • Do not connect the drain piping directly to sewage pipes that smell of ammonia. The ammonia in the sewage might enter the indoor unit through the drain piping and corrode the heat exchanger. • Do not twist or bend the drain hose (2), so that excessive force is not applied to it. (This type of treatment may cause leaking.
