It may result in electricshock.- Confirm the drain operation looking at the drain socket.- After checking the drainage flow, turn off power, removethe control box lid and disconnect the single phase powersupply from the inter unit wiring terminal block again.Attach the control box lid as before.Electric wiring workGeneral instructions All field wiring and components must be installed by a licensedelectrician and must comply with relevant European and nationalregulations. Use copper wire only. Follow the 'Wiring diagram' attached to the unit body to wire theoutdoor unit, indoor units and the remote controller. For detailson hooking up the remote controller, refer to the "Installationmanual of the remote controller". All wiring must be performed by an authorized electrician. A main switch or other means for disconnection, having acontact separation in all poles, must be incorporated in the fixedwiring in accordance with relevant local and national legislation.Note that the operation will restart automatically if the mainpower supply is turned off and then turned back on again. Refer to the installation manual attached to the outdoor unit forthe size of power supply electric wire connected to the outdoorunit, the capacity of the earth leakage circuit breaker and fuse,and wiring instructions. Be sure to ground the air conditioner. Do not connect the ground wire to:- gas pipes: might cause explosions or fire if gas leaks.- telephone ground wires or lightning rods: might causeabnormally high electric potential in the ground duringlightning storms.- plumbing pipes: no grounding effect if hard vinyl piping isused. Be sure that the shape of the power supply cable and any othercable, before entering unit, should be as shown in this figure.Electrical characteristicsSpecifications for field wire1 Plastic watering can (tube should be about 100 mm long)2 Service drain outlet (with rubber plug) (Use this outlet todrain water from the drain pan)3 Drain pump location4 Drain pipe5 Drain socket (water flow view point)1 Control box lid2 Inter unit wiring3 Earth cable4 Terminal block for power supply5 Clamp6 Transmission wiring7 Terminal board for transmission wiring8 Opening for cables9 Wiring diagram label(on the back side of the control box lid)10 Remote controller wiringTerminal block for power supply (4)21 3NOTE For details, refer to "Electrical data".Wire Size (mm2 ) LengthBetweenindoor units H05VV-U4G (1),(2)(1) Shows only in case of protected pipes.
