If you are NOT sure how to install or operate the unit, contact your dealer.
NOTICE
Improper installation or attachment of equipment or accessories could result in electric shock, short-circuit, leaks, fire or other damage to the equipment. Only use accessories, optional equipment and spare parts made or approved by Daikin.
WARNING
Make sure installation, testing and applied materials comply with applicable legislation (on top of the instructions described in the Daikin documentation).
CAUTION
Wear adequate personal protective equipment (protective gloves, safety glasses,…) when installing, maintaining or servicing the system.
WARNING
Tear apart and throw away plastic packaging bags so that nobody, especially children, can play with them. Possible risk: suffocation.
1.2.2Installation site
▪Provide sufficient space around the unit for servicing and air circulation.
▪Make sure the installation site withstands the unit's weight and vibration.
▪Make sure the area is well ventilated. Do NOT block any ventilation openings.
▪Make sure the unit is level.
Do NOT install the unit in the following places:
▪In potentially explosive atmospheres.
▪In places where there is machinery that emits electromagnetic waves. Electromagnetic waves may disturb the control system, and cause malfunction of the equipment.
▪In places where there is a risk of fire due to the leakage of flammable gases (example: thinner or gasoline), carbon fibre, ignitable dust.
▪In places where corrosive gas (example: sulphurous acid gas) is produced. Corrosion of copper pipes or soldered parts may cause the refrigerant to leak.
1.2.3Water
If applicable. See the installation manual or installer reference guide of your application for more information.
DANGER: RISK OF BURNING
▪Do NOT touch the refrigerant piping, water piping or internal parts during and immediately after operation. It could be too hot or too cold. Give it time to return to normal temperature. If you must touch it, wear protective gloves.
▪Do NOT touch any accidental leaking refrigerant.
WARNING
Provide adequate measures to prevent that the unit can be used as a shelter by small animals. Small animals that make contact with electrical parts can cause malfunctions, smoke or fire.
CAUTION
Do NOT touch the air inlet or aluminium fins of the unit.
NOTICE
▪Do NOT place any objects or equipment on top of the unit.
NOTICE
Make sure water quality complies with EU directive 98/83 EC.
1.2.4Electrical
DANGER: RISK OF ELECTROCUTION
▪Turn OFF all power supply before removing the switch box cover, connecting electrical wiring or touching electrical parts.
▪Disconnect the power supply for more than 1 minute, and measure the voltage at the terminals of main circuit capacitors or electrical components before servicing. The voltage MUST be less than 50 V DC before you can touch electrical components. For the location of the terminals, see the wiring diagram.
▪Do NOT touch electrical components with wet hands.
▪Do NOT leave the unit unattended when the service cover is removed.
▪ Do NOT sit, climb or stand on the unit.
NOTICE
Works executed on the outdoor unit are best done under dry weather conditions to avoid water ingress.
WARNING
If NOT factory installed, a main switch or other means for disconnection, having a contact separation in all poles providing full disconnection under overvoltage category III condition, MUST be installed in the fixed wiring.

2 About the documentation
WARNING
▪ONLY use copper wires.
▪Make sure the field wiring complies with the applicable legislation.
▪All field wiring MUST be performed in accordance with the wiring diagram supplied with the product.
▪NEVER squeeze bundled cables and make sure they do NOT come in contact with the piping and sharp edges. Make sure no external pressure is applied to the terminal connections.
▪Make sure to install earth wiring. Do NOT earth the unit to a utility pipe, surge absorber, or telephone earth. Incomplete earth may cause electrical shock.
▪Make sure to use a dedicated power circuit. NEVER use a power supply shared by another appliance.
▪Make sure to install the required fuses or circuit breakers.
▪Make sure to install an earth leakage protector. Failure to do so may cause electric shock or fire.
▪When installing the earth leakage protector, make sure it is compatible with the inverter (resistant to high frequency electric noise) to avoid unnecessary opening of the earth leakage protector.
NOTICE
Precautions when laying power wiring:
▪Do NOT connect wiring of different thicknesses to the power terminal block (slack in the power wiring may cause 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 connect firmly, then secure to prevent outside pressure being exerted on the terminal board.
▪Use an appropriate screwdriver for tightening the terminal screws. A screwdriver with a small head will damage the head and make proper tightening impossible.
▪Over-tightening the terminal screws may break them.
WARNING
▪After finishing the electrical work, confirm that each electrical component and terminal inside the electrical components box is connected securely.
▪Make sure all covers are closed before starting up the unit.
NOTICE
Only applicable if the power supply is three phase, and the compressor has an ON/OFF starting method.
If there exists the possibility of reversed phase after a momentary black out and the power goes on and off while the product is operating, attach a reversed phase protection circuit locally. Running the product in reversed phase can break the compressor and other parts.
