5 ELECTRICAL CONNECTION
• The heat pump should use separate power supply with rated voltage. If voltage is not stable, please use stabilized
voltage supply.
• Theexternalpowersupplytotheheatpumpshouldhavegroundwiring,whichislinkedtothegroundwiringofthe
indoor andoutdoor unit.
• Thewiringworkshouldbedonebyqualiedpersonsaccordingtocircuitdrawing.
• A leakage protector should be installed according to the National Standard concerning electrical appliance.
• An all-pole disconnection device which has at least 3mm separation distance in contact points should be installed.
• Power supply cords and signal wires should be arranged properly. Separate strong current wire and weak current
wire, meanwhile they can’t contant with connection pipe and valve.
• Power supply with a leakage protector should be installed in a water-proof place inside the room.
• Don’t do cross connection between 2 wires and signal wires must be shielded.
• When power supply cord parallels with controlling wire, please put the wires to corresponding wire pipe and leave
proper spac between wires.
• When selecting power supply cords, please refer to to the National Standard and this manual, power supply used
outdoor should not lighter than NO.57 wire in IEC 60245.
• If power supply cord is damaged, to avoid danger, it must be replaced by professional person.
• Do not turn on the power until you have checked carefully after wiring.
