For the installer
1.2.1
General
If you are NOT sure how to install or operate the unit, contact your
dealer.
DANGER: RISK OF BURNING/SCALDING
▪ 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
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 unless otherwise specified.
WARNING
Make sure installation, testing and applied materials
comply with applicable legislation (on top of the
instructions described in the Daikin documentation).
WARNING
Tear apart and throw away plastic packaging bags so that
nobody, especially NOT children, can play with them.
Possible consequence:
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
Wear adequate personal protective equipment (protective
gloves, safety glasses,…) when installing, maintaining or
servicing the system.
CAUTION
Do NOT touch the air inlet or aluminium fins of the unit.
CAUTION
▪ Do NOT place any objects or equipment on top of the
unit.
▪ Do NOT sit, climb or stand on the unit.
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.
1.2.2
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.
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.
1.2.3
Water
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
2020/2184.

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.
