16• Pump down operation- Operate the pump down according to the following procedures.7.1.9. Electrical wiring• Connect the power supply wiring and indoor/outdoor unit connection wiring according to the electrical circuit diagraminstructions.• Clamp the wires securely to the terminal connections using cord clamps so that no undue force is placed on the wires.• Once all wiring work has been completed, tie the wires and cords together with the binding strap so that they do not touch otherparts such as the compressor and pipes.Procedure Notes1. Confirm the valve on the liquid side and the gas side is surely open.2. Press the PUMP DOWN switch on outdoor printed board for 1second or more.Perform the cooling operation for five minutes or more.3. Shut the valve on the liquid side surely. When the valve is shut halfway, the compressor is occasionallydamaged.WarningThe units must be connected to the supply cables for fixed wiring by qualified technician.Feed the power source to the unit via a distribution switch board designed for this purpose, the switch should disconnected allpoles with a contact separation of at least 3mm.When the supply cable is damaged, it must be replaced by qualified technician.Warning Be sure to install a current leakage breaker, main switch and fuse to the main power supply, otherwise electric shocks mayresult.WarningBe sure to connect the unit to secure earth connection.If the earthing work is not carried out properly, electric shocks may result.WarningWiring shall be connected securely by using specified cables and fix them securely so that external force of the cables may nottransfer to the terminal connection section.Imperfect connection and fixing leads to fire, etc.1. Connect the power supply line to a 3-phase/380-415V (or single-phase 220-240V)power supply.2. The equipment shall be connected to a suitable mains network with a mainimpedance less than the valve indicated in the table of power supply specifications.3. Be sure to connect the wires correctly to terminal board with connecting the crimptype ring terminal to the wires.4. The binding screws inside the power supply box may become loosened due tovibration during transportation, so check that they are tightened securely.5. Tighten the binding screws to the specified torque while referring to the tablebelow.6. If connecting two separate wires to a single crimped terminal, place the twocrimped terminal wires together as shown in Fig. A. (If the arrangement shown inFig. B is used, poor contacts or contact damage may result.)7. If momentarily turning on the power supply for both the indoor and outdoor units,do not turn the power off again until at least 1 minute has passed (except when areversed phase has been detected).WarningUse only the specified cables for wiring connections. Connect the cable securely, and secure them properly so that no undueforce will be applied to the terminal connections.If the terminals are loose or if the wires are not connected securely, fire may result.Terminal screw Tightening torque N.cm {kgf.cm}M3 69 ~ 98 {7 ~ 10}M4 157 ~ 196 {16 ~ 20}M5 196 ~ 245 {20 ~ 25}
