2 General safety precautions
2.1 About the documentation
▪ The original documentation is written in English. All other
languages are translations.
▪ The precautions described in this document cover very important
topics, follow them carefully.
▪ The installation of the system, and all activities described in the
installation manual and in the installer reference guide MUST be
performed by an authorised installer.
2.1.1 Meaning of warnings and symbols
DANGER
Indicates a situation that results in death or serious injury.
DANGER: RISK OF ELECTROCUTION
Indicates a situation that could result in electrocution.
WARNING
Indicates a situation that could result in death or serious
injury.
CAUTION
Indicates a situation that could result in minor or moderate
injury.
NOTICE
Indicates a situation that could result in equipment or
property damage.
INFORMATION
Indicates useful tips or additional information.
2.2 For the installer
2.2.1 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.
2.2.2 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.

2.2.3 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.
2.3 For the user
WARNING
If you are NOT sure how to operate the
unit, contact your installer.
