1 About the documentation

1.1 About this document

INFORMATION

Make sure that the user has the printed documentation and
ask him/her to keep it for future reference.

Target audience

Authorised installers

WARNING

Make sure installation, servicing, maintenance, repair and
applied materials follow the instructions from Daikin and, in
addition, comply with applicable legislation and are
performed by qualified persons only. In Europe and areas
where IEC standards apply, EN/IEC 60335-2-40 is the
applicable standard.

INFORMATION

This document only describes installation instructions
specific to the outdoor unit. For installation of the indoor
unit (mounting the indoor unit, connecting the refrigerant
piping to the indoor unit, connecting the electrical wiring to
the indoor unit …), see the installation manual of the indoor
unit.

Documentation set

This document is part of a documentation set. The complete set
consists of:

▪ General safety precautions:

▪ Safety instructions that you MUST read before installing

▪ Format: Paper (in the box of the outdoor unit)

▪ Outdoor unit installation manual:

▪ Installation instructions

▪ Format: Paper (in the box of the outdoor unit)

▪ Installer reference guide:

▪ Preparation of the installation, reference data,…

▪ Format: Digital files on http://www.daikineurope.com/support-

and-manuals/product-information/

Latest revisions of the supplied documentation may be available on
the regional Daikin website or via your dealer.

The original documentation is written in English. All other languages
are translations.

Technical engineering data

▪ A subset of the latest technical data is available on the regional

Daikin website (publicly accessible).

▪ The full set of latest technical data is available on the Daikin

Business Portal (authentication required).

2 Specific installer safety

instructions

Always observe the following safety instructions and regulations.

Unit installation (see "4Unit installation"[45])

WARNING

Installation shall be done by an installer, the choice of
materials and installation shall comply with the applicable
legislation. In Europe, EN378 is the applicable standard.

2 Specific installer safety instructions

Installation site (see "4.1Preparing the installation site"[45])

CAUTION

▪ Check if the installation location can support the unit's

weight. Poor installation is hazardous. It can also cause
vibrations or unusual operating noise.

▪ Provide sufficient service space.

▪ Do NOT install the unit so that it is in contact with a

ceiling or a wall, as this may cause vibrations.

WARNING

The appliance shall be stored in a room without
continuously operating ignition sources (example: open
flames, an operating gas appliance or an operating electric
heater).

Connecting the refrigerant piping (see "5.2Connecting the

refrigerant piping"[47])

CAUTION

▪ No brazing or welding on site for units with R32

refrigerant charge during shipment.

▪ During installation of the refrigeration system, joining of

parts with at least one part charged shall be performed
taking into account the following requirements: inside
occupied spaces non permanent joints are not allowed
for R32 refrigerant except for site made joints directly
connecting the indoor unit to piping. Site made joints
directly connecting piping to indoor units shall be of non
permanent type.

CAUTION

▪ Use the flare nut fixed to the unit.

▪ To prevent gas leakage, apply refrigeration oil only to

the inside of the flare. Use refrigeration oil for R32.

▪ Do NOT reuse joints.

CAUTION

▪ Do NOT use mineral oil on flared part.

▪ Do NOT reuse piping from previous installations.

▪ NEVER install a drier to this R32 unit to guarantee its

lifetime. The drying material may dissolve and damage
the system.

WARNING

Connect the refrigerant piping securely before running the
compressor. If the refrigerant piping is NOT connected and
the stop valve is open when the compressor is run, air will
be sucked in. This will cause abnormal pressure in the
refrigeration cycle, which may result in equipment damage
and even injury.

CAUTION

▪ Incomplete flaring may cause refrigerant gas leakage.

▪ Do NOT re-use flares. Use new flares to prevent

refrigerant gas leakage.

▪ Use flare nuts that are included with the unit. Using

different flare nuts may cause refrigerant gas leakage.

CAUTION

Do NOT open the valves before flaring is complete. This
would cause refrigerant gas leakage.

DANGER: RISK OF EXPLOSION

Do NOT start the unit if it is vacuumed.

Charging refrigerant (see "6Charging refrigerant"[48])

WARNING

The refrigerant inside the unit is mildly flammable, but
normally does NOT leak. If the refrigerant leaks in the
room and comes in contact with fire from a burner, a
heater, or a cooker, this may result in fire, or the formation
of a harmful gas.

Turn off any combustible heating devices, ventilate the
room, and contact the dealer where you purchased the
unit.

Do NOT use the unit until a service person confirms that
the part from which the refrigerant leaked has been
repaired.

WARNING

▪ Only use R32 as refrigerant. Other substances may

cause explosions and accidents.

▪ R32 contains fluorinated greenhouse gases. Its global

warming potential (GWP) value is 675. Do NOT vent
these gases into the atmosphere.

▪ When charging refrigerant, ALWAYS use protective

gloves and safety glasses.

CAUTION

To avoid compressor breakdown, do NOT charge more
than the specified amount of refrigerant.

WARNING

NEVER directly touch any accidental leaking refrigerant.
This could result in severe wounds caused by frostbite.

Electrical installation (see "7Electrical installation"[49])

WARNING

Appliance shall be installed in accordance with national
wiring regulations.

WARNING

▪ All wiring MUST be performed by an authorised

electrician and MUST comply with the applicable
legislation.

▪ Make electrical connections to the fixed wiring.

▪ All components procured on-site and all electrical

construction MUST comply with the applicable
legislation.

WARNING

▪ If the power supply has a missing or wrong N-phase,

equipment might break down.

▪ Establish proper earthing. Do NOT earth the unit to a

utility pipe, surge absorber, or telephone earth.
Incomplete earthing may cause electrical shock.

▪ Install the required fuses or circuit breakers.

▪ Secure the electrical wiring with cable ties so that the

cables do NOT come in contact with sharp edges or
piping, particularly on the high-pressure side.

▪ Do NOT use taped wires, stranded conductor wires,

extension cords, or connections from a star system.
They can cause overheating, electrical shock or fire.

▪ Do NOT install a phase advancing capacitor, because

this unit is equipped with an inverter. A phase
advancing capacitor will reduce performance and may
cause accidents.

WARNING

ALWAYS use multicore cable for power supply cables.

WARNING

Use an all-pole disconnection type breaker with at least
3 mm between the contact point gaps that provide full
disconnection under overvoltage category III.

WARNING

If the supply cord is damaged, it MUST be replaced by the
manufacturer, its service agent or similarly qualified
persons in order to avoid a hazard.

WARNING

Do NOT connect the power supply to the indoor unit. This
could result in electrical shock or fire.

WARNING

▪ Do NOT use locally purchased electrical parts inside

the product.

▪ Do NOT branch the power supply for the drain pump,

etc. from the terminal block. This could result in
electrical shock or fire.

WARNING

Keep the interconnection wiring away from copper pipes
without thermal insulation as such pipes will be very hot.
