13 English7-4 Transmission wiring connection procedure• If an excessive force is applied while connecting a cable to theterminal block on the PC board, the PC board may be damaged.CAUTION• For low-noise operation, it is necessary to install the optional “Exter-nal control adaptor for outdoor unit”.For details, see the installation manual attached to the adaptor.Make sure to observe the restrictions below. If they are notobserved, transmission error may occur.Maximum wiring length: 3280 ft.• Never connect 208/230V to the terminal block for the transmissionwiring.Doing so will break the entire system.• The transmission wiring from the indoor unit must be connected tothe F1/F2 (TO IN/D UNIT) terminals on the PC board in the outdoorunit.∗ Make sure to use sheathed two-core cables of AWG18-16 in the wir-ing shown above.∗ All cables used in the wiring between the units should be pro-cured on the site.8. CHECKS AFTER COMPLETION OFWORKAfter completing the work, make sure to confirm the followingitems:1. Connection of drain piping and removal of transportation metal:Refer to “5. CAUTIONS ON INSTALLATION”.2. Connection of power supply wiring and tightening of screws:Refer to “7-3 Power supply wiring connection procedure”.3. Connection of transmission wiring and tightening of screws:Refer to “7-4 Transmission wiring connection procedure”.4. Freezing connection of refrigerant pipingRefer to “6. REFRIGERANT PIPING WORK”.5. Piping size and heat insulation:Refer to “6-1 Selection of piping material”, “6-5 Heat insulationof piping”.6. Check of stop valve:Confirm that the stop valve is open on both the liquid line and gasline.7. Record of amount of additional refrigerant:Record the amount on the label stuck on the back of the front panel.8. Measurement of insulation in main power circuit:• Use the megatester for 500 V.• Do not use any megatester for low voltage electric circuits except230 V.(Wiring between the outdoor unit and the indoor unit)CAUTION• Make sure to open the stop valve after finishing the piping work.(Operating the air conditioner with the stop valve shut may damagethe compressor.)9. TEST RUN PROCEDUREA crankcase heater is mounted for smooth startup. Make sure toturn on the power 6 hours before starting operation for supplyingthe power to the crankcase heater.WARNING• Make sure to close the front panel before leaving the outdoorunit in the power ON status.• To avoid injury, always make sure that the circuit breaker onthe power supply panel of the installation is switched off before doingany work.Cautions before turning on the power• Put the insulating cover securely onto the control box.• After turning on the power, check the settings and LED indica-tors on the PC board (A2P) in the outdoor unit through theopening of the insulating cover.Caution on the wiring length between unitsCautions on the wiring between unitsF1 F2 F1 F2F1 F2Terminal block (X2M)Use the conductorof sheathed wire(2 wire) (no polarity)Indoor unit
