(Otherwise, the system will be failed. ) · Perform the electric wiring so that it does not come to contact with the high-temperature part of the pipe. The coating may melt resulted in an accident. · After connecting wires to the terminal blocks, provide a trap and fix wires with the wire clamp. · Store the refrigerant piping line and control wiring line in the same line. · Do not turn on the power of the indoor unit until vacuuming of the refrigerant pipes completes. 100mm) on a wire to hang down the electric parts box at servicing, etc. 13 6 ELECTRIC WORK Power supply specifications Power supply cord and communication wires are procured locally. For the power supply specifications, follow to the table below. If capacity is little, it is dangerous because overheat or seizure may be caused. For specifications of the power capacity of the outdoor unit and the power supply wires, refer to the Installation Manual attached to the outdoor unit. Power supply Power supply (*1) 220­240V ~ 50Hz, 220V ~ 60Hz Power supply switch/Earth leakage breaker or power supply wiring/fuse rating for indoor units should be selected by the accummulated total current values of the indoor units. * The setup change for wireless remote controller, sub remote controller, or remote controller-less system (Central control remote controller only is provided. ) is impossible. In these cases, prepare and mount a separate main remote controller. CODE No. Exchange of applicable control setup Basic operation procedure for setup exchange Change the setup while operation of the equipment stops.

Check that the displayed item code is [10]. · If the item code indicates other than [10], push button to erase the display, and then retry the operation from the first step. button has been pushed, the operation (For some time after R. C. of the remote controller cannot be accepted. ) (In a group control, the firstly displayed indoor unit No. becomes the center unit. ) (* The display changes according to the indoor unit model. ) Every pushing UNIT button, the indoor unit No. in the group control is displayed successively. Select an indoor unit of which setup to be changed. [. . . ] Most importantly, the multi air conditioner system is able to replenish a large amount of refrigerant compared with conventional individual air conditioners. If a single unit of the multi conditioner system is to be installed in a small room, select a suitable model and installation procedure so that if the refrigerant accidentally leaks out, its concentration does not reach the limit (and in the event of an emergency, measures can be made before injury can occur). In a room where the concentration may exceed the limit, create an opening with adjacent rooms, or install mechanical ventilation combined with a gas leak detection device. volume of the indoor unit installed room (m³) Concentration limit (kg/m³) The concentration limit of R410A which is used in multi air conditioners is 0. 3kg/m³.
