1 General safety precautions
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.
▪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.
WARNING
Tear apart and throw away plastic packaging bags so that nobody, especially children, can play with them. Possible risk: suffocation.
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.
▪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.
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.
▪Provide sufficient space around the unit for servicing and air circulation.
▪Make sure the installation site withstands the weight and vibration of the unit.
If applicable.
WARNING
▪Do NOT pierce or burn.
▪Do NOT use means to accelerate the defrosting process or to clean the equipment, other than those recommended by the manufacturer.
▪Be aware that R32 refrigerant does NOT contain an odour.
WARNING
The appliance shall be stored so as to prevent mechanical damage and in a well-ventilated room without continuously operating ignition sources (example: open flames, an operating gas appliance or an operating electric heater) and have a room size as specified below.
NOTICE
▪Do NOT re-use joints which have been used already.
▪Joints made in installation between parts of refrigerant system shall be accessible for maintenance purposes.
WARNING
Make sure installation, servicing, maintenance and repair comply with instructions from Daikin and with applicable legislation (for example national gas regulation) and are executed only by authorised persons.
NOTICE
▪Pipework shall be protected from physical damage.
▪Installation of pipework shall be kept to a minimum.
WARNING
If appliances contain R32 refrigerant, the floor area of the room in which the appliances are installed, operated and stored MUST be larger than the minimum floor area defined in table below A (m2). This applies to:
▪Indoor units without a refrigerant leakage sensor; in case of indoor units with refrigerant leakage sensor, consult the installation manual
▪Outdoor units installed or stored indoors (e.g. winter garden, garage, machinery room)
▪Pipework in unventilated spaces

1 General safety precautions
DANGER: RISK OF EXPLOSION
Pump down – Refrigerant leakage. If you want to pump down the system, and there is a leak in the refrigerant circuit:
▪Do NOT use the unit's automatic pump down function, with which you can collect all refrigerant from the system into the outdoor unit. Possible consequence:
Self-combustion and explosion of the compressor because of air going into the operating compressor.
▪Use a separate recovery system so that the unit's compressor does NOT have to operate.
WARNING
ALWAYS recover the refrigerant. Do NOT release them directly into the environment. Use a vacuum pump to evacuate the installation.
NOTICE
After all the piping has been connected, make sure there is no gas leak. Use nitrogen to perform a gas leak detection.
NOTICE
▪To avoid compressor breakdown, do NOT charge more than the specified amount of refrigerant.
▪When the refrigerant system is to be opened, refrigerant MUST be treated according to the applicable legislation.
WARNING
Make sure there is no oxygen in the system. Refrigerant may only be charged after performing the leak test and the vacuum drying.
▪In case re-charge is required, refer to the nameplate of the unit. It states the type of refrigerant and necessary amount.
▪The unit is factory charged with refrigerant and depending on pipe sizes and pipe lengths some systems require additional charging of refrigerant.
▪Only use tools exclusively for the refrigerant type used in the system, this to ensure pressure resistance and prevent foreign materials from entering into the system.
▪Charge the liquid refrigerant as follows:
If |
Then |
A siphon tube is present |
Charge with the cylinder upright. |
(i.e., the cylinder is marked with "Liquid filling siphon attached")
A siphon tube is NOT present |
Charge with the cylinder upside |
|
down. |
▪Open refrigerant cylinders slowly.
▪Charge the refrigerant in liquid form. Adding it in gas form may prevent normal operation.
CAUTION
When the refrigerant charging procedure is done or when pausing, close the valve of the refrigerant tank immediately. If the valve is NOT closed immediately, remaining pressure might charge additional refrigerant.
Possible consequence: Incorrect refrigerant amount.
If applicable. See the installation manual or installer reference guide of your application for more information.
WARNING
The selection of the brine MUST be in accordance with the applicable legislation.
WARNING
Take sufficient precautions in case of brine leakage. If brine leaks, ventilate the area immediately and contact your local dealer.
WARNING
The ambient temperature inside the unit can get much higher than that of the room, e.g. 70°C. In case of a brine leak, hot parts inside the unit can create a hazardous situation.
WARNING
The use and installation of the application MUST comply with the safety and environmental precautions specified in the applicable legislation.
If applicable. See the installation manual or installer reference guide of your application for more information.
NOTICE
Make sure water quality complies with EU directive 98/83 EC.
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.
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 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.
CAUTION
When connecting the power supply, the earth connection must be made before the current-carrying connections are established. When disconnecting the power supply, the current-carrying connections must be separated before the earth connection is. 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.
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.

5 Preparation
▪ Preparing the electrical wiring
5.2Preparing the installation site
Do NOT install the unit in places often used as work place. In case of construction works (e.g. grinding works) where a lot of dust is created, the unit MUST be covered.
Choose an installation location with sufficient space for carrying the unit in and out of the site.
INFORMATION
Also read the following requirements:
▪General installation site requirements. See the "General safety precautions" chapter.
▪Refrigerant piping requirements (length, height difference). See further in this "Preparation" chapter.
INFORMATION
The sound pressure level is less than 70 dBA.
CAUTION
Appliance not accessible to the general public, install it in a secured area, protected from easy access.
This unit, both indoor and outdoor, is suitable for installation in a commercial and light industrial environment.
Do NOT install the unit in the following places:
▪In places where a mineral oil mist, spray or vapour may be present in the atmosphere. Plastic parts may deteriorate and fall off or cause water leakage.
It is NOT recommended to install the unit in the following places because it may shorten the life of the unit:
▪Where the voltage fluctuates a lot
▪In vehicles or vessels
▪Where acidic or alkaline vapour is present
NOTICE
The equipment described in this manual may cause electronic noise generated from radio-frequency energy. The equipment complies to specifications that are designed to provide reasonable protection against such interference. However, there is no guarantee that interference will not occur in a particular installation.
It is therefore recommended to install the equipment and electric wires keeping proper distances away from stereo equipment, personal computers, etc.

5 Preparation
In places with weak reception, keep distances of 3 m or more to avoid electromagnetic disturbance of other equipment and use conduit tubes for power and transmission lines.
▪Fluorescent lights. When installing a wireless user interface in a room with fluorescent lights, mind the following to avoid interference:
▪Install the wireless user interface as close as possible to the indoor unit.
▪Install the indoor unit as far as possible from the fluorescent lights.
▪Take care that in the event of a water leak, water cannot cause any damage to the installation space and surroundings.
▪Choose a location where the hot/cold air discharged from the unit or the operation noise, will NOT disturb anyone.
▪Air flow. Make sure nothing blocks the air flow.
▪Drainage. Make sure condensation water can be evacuated properly.
▪Paper pattern for installation (upper part of packing) (accessory). When selecting the installation location, use the paper pattern. It contains the dimensions of the unit and the required ceiling opening.
▪Air flow directions. You can select different air flow directions. Choose the one best suited for the room. Also make sure the "Air flow direction" field setting corresponds with the actual situation (see "7.1 Field settings" on page 17).
