If the valve is NOT closed immediately,remaining pressure might charge additional refrigerant.Possible consequence: Incorrect refrigerant amount.1.2.4 BrineIf applicable. See the installation manual or installer reference guideof your application for more information.WARNINGThe selection of the brine MUST be in accordance with theapplicable legislation.WARNINGTake sufficient precautions in case of brine leakage. Ifbrine leaks, ventilate the area immediately and contactyour local dealer.WARNINGThe ambient temperature inside the unit can get muchhigher than that of the room, e.g. 70°C. In case of a brineleak, hot parts inside the unit can create a hazardoussituation.WARNINGThe use and installation of the application MUST complywith the safety and environmental precautions specified inthe applicable legislation.1.2.5 WaterIf applicable. See the installation manual or installer reference guideof your application for more information.NOTICEMake sure water quality complies with EU directive98/83 EC.1.2.6 ElectricalDANGER: RISK OF ELECTROCUTION▪ Turn OFF all power supply before removing theswitch box cover, connecting electrical wiring ortouching electrical parts.▪ Disconnect the power supply for more than 1 minute,and measure the voltage at the terminals of main circuitcapacitors or electrical components before servicing.The voltage MUST be less than 50 V DC before youcan touch electrical components. For the location of theterminals, see the wiring diagram.▪ Do NOT touch electrical components with wet hands.▪ Do NOT leave the unit unattended when the servicecover is removed.WARNINGIf NOT factory installed, a main switch or other means fordisconnection, having a contact separation in all polesproviding full disconnection under overvoltage category IIIcondition, MUST be installed in the fixed wiring.WARNING▪ ONLY use copper wires.▪ Make sure the field wiring complies with the applicablelegislation.▪ All field wiring MUST be performed in accordance withthe wiring diagram supplied with the product.▪ NEVER squeeze bundled cables and make sure theydo NOT come in contact with the piping and sharpedges. Make sure no external pressure is applied to theterminal connections.▪ Make sure to install earth wiring. Do NOT earth the unitto a utility pipe, surge absorber, or telephone earth.Incomplete earth may cause electrical shock.▪ Make sure to use a dedicated power circuit. NEVERuse a power supply shared by another appliance.▪ Make sure to install the required fuses or circuitbreakers.▪ Make sure to install an earth leakage protector. Failureto do so may cause electric shock or fire.▪ When installing the earth leakage protector, make sureit is compatible with the inverter (resistant to highfrequency electric noise) to avoid unnecessary openingof the earth leakage protector.NOTICEPrecautions when laying power wiring:▪ Do NOT connect wiring of different thicknesses to thepower terminal block (slack in the power wiring maycause abnormal heat).▪ When connecting wiring which is the same thickness,do as shown in the figure above.▪ For wiring, use the designated power wire and connectfirmly, then secure to prevent outside pressure beingexerted on the terminal board.▪ Use an appropriate screwdriver for tightening theterminal screws. A screwdriver with a small head willdamage the head and make proper tighteningimpossible.▪ Over-tightening the terminal screws may break them.WARNING▪ After finishing the electrical work, confirm that eachelectrical component and terminal inside the electricalcomponents box is connected securely.▪ Make sure all covers are closed before starting up theunit.NOTICEOnly applicable if the power supply is three‑phase, and thecompressor has an ON/OFF starting method.If there exists the possibility of reversed phase after amomentary black out and the power goes on and off whilethe product is operating, attach a reversed phaseprotection circuit locally. Running the product in reversedphase can break the compressor and other parts.
