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.
1.3.2 Installation site
▪ Provide sufficient space around the unit for servicing and air
circulation.
▪ Make sure the installation site withstands the unit's weight and
vibration.
▪ 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.
Instructions for equipment using R32 refrigerant
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.
Installation space requirements
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 (m
2
). 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
To determine the minimum floor area
1 Determine the total refrigerant charge in the system (= factory
refrigerant charge
+ additional refrigerant amount
charged).

▪ For indoor units: Is the unit ceiling-mounted, wall-mounted or
floor-standing?
▪ For outdoor units installed or stored indoors, and field piping
in unventilated spaces, this depends on the installation
