For the installer

General

If you are NOT sure how to install or operate the unit, contact your dealer.

WARNING
Improper installation or attachment of equipment or accessories could result in electrical 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.

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 place any objects or equipment on top of the unit.
• Do NOT sit, climb or stand on the unit.

DANGER: RISK OF BURNING/SCALDING
Do NOT touch the heating element of the unit, 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.

In accordance with the applicable legislation, it might be necessary to provide a logbook with the product containing at least: information on maintenance, repair work, results of tests, stand-by periods,…

Also, at least, following information MUST be provided at an accessible place at the product:

• Instructions for shutting down the system in case of an emergency
• Name and address of fire department, police and hospital
• Name, address and day and night telephone numbers for obtaining service

In Europe, EN378 provides the necessary guidance for this logbook.

Installation site

• Provide sufficient space around the unit for servicing and air circulation.
• Make sure the installation site withstands the weight and vibration of the unit.
• Make sure the area is well ventilated. Do NOT block any ventilation openings.
• Make sure the unit is level.
• Make sure that the floor, where the unit will be installed, 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.
• In bathrooms.
• In places where frost is possible. The ambient temperature around the indoor unit should be >5°C.

Electrical

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 10 minutes, 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.

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.

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 electrical 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.

CAUTION

• When connecting the power supply: connect the earth cable first, before making the current-carrying connections.
• When disconnecting the power supply: disconnect the current-carrying cables first, before separating the earth connection.
• The length of the conductors between the power supply stress relief and the terminal block itself must be as such that the current-carrying wires are tautened before the earth wire is in case the power supply is pulled loose from the stress relief.

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.

Install power cables at least 1 m away from televisions or radios to prevent interference. Depending on the radio waves, a distance of 1 m may not be sufficient.

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.

For the user

WARNING
If you are NOT sure how to operate the unit, contact your installer.
