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.

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.

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, 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.
