1 General safety precautions

1.2 For the installer

1.2.1 General

If you are not sure how to install or operate the unit, contact your
dealer.

NOTICE

Improper installation or attachment of equipment or
accessories could result in electric 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.

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.

1.2.2 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.

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.

Installer reference guide

4

NOTICE

▪ Do NOT reuse 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.

(i.e., the cylinder is marked with
"Liquid filling siphon attached")

A siphon tube is NOT present Charge with the cylinder upside

Charge with the cylinder upright.

down.

WARNING

Take sufficient precautions in case of refrigerant leakage. If
refrigerant gas leaks, ventilate the area immediately.
Possible risks:

▪ Excessive refrigerant concentrations in a closed room

can lead to oxygen deficiency.

▪ Toxic gas may be produced if refrigerant gas comes

into contact with fire.

DANGER: RISK OF EXPLOSION
Pump down – Refrigerant leakage. If you want to pump

down the system, and there is a leakage in the refrigerant
circuit:

▪ Do NOT use the unit's automatic pump down function,

with which you can collect all refrigerant from the
system into the outdoor unit. Possible consequence:
Self-combustion and explosion of the compressor
because of air going into the operating compressor.

▪ Use a separate recovery system so that the unit's

compressor does NOT have to operate.

WARNING

Always recover the refrigerant. Do NOT release them
directly into the environment. Use a vacuum pump to
evacuate the installation.

NOTICE

After all the piping has been connected, make sure there is
no gas leak. Use nitrogen to perform a gas leak detection.

▪ Open refrigerant cylinders slowly.

▪ Charge the refrigerant in liquid form. Adding it in gas form may

prevent normal operation.

CAUTION

When the refrigerant charging procedure is done or when
pausing, close the valve of the refrigerant tank
immediately. If the valve is not closed immediately,
remaining pressure might charge additional refrigerant.

Possible consequence: Incorrect refrigerant amount.

1.2.4 Brine

If applicable. See the installation manual or installer reference guide
of your application for more information.

WARNING

The selection of the brine MUST be in accordance with the
applicable legislation.

WARNING

6.3.4 Pipe bending guidelines

Use a pipe bender for bending. All pipe bends should be as gentle
as possible (bending radius should be 30~40mm or larger).

6.3.5 To flare the pipe end

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.

1 Cut the pipe end with a pipe cutter.

c Make sure the flare nut is fitted.

6.3.6 To braze the pipe end

The indoor unit and outdoor unit have flare connections. Connect
both ends without brazing. If brazing should be needed, take the
following into account:

▪ When brazing, blow through with nitrogen to prevent creation of

large quantities of oxidised film on the inside of the piping. This
film adversely affects valves and compressors in the refrigerating
system and prevents proper operation.

▪ Set the nitrogen pressure to 20 kPa (0.2bar) (just enough so it

can be felt on the skin) with a pressure-reducing valve.

a Refrigerant piping
b Part to be brazed
c Taping
d Manual valve
e Pressure-reducing valve

f Nitrogen

▪ Do NOT use anti-oxidants when brazing pipe joints.

Residue can clog pipes and break equipment.

▪ Do NOT use flux when brazing copper-to-copper refrigerant

piping. Use phosphor copper brazing filler alloy (BCuP), which
does not require flux.
Flux has an extremely harmful influence on refrigerant piping
systems. For instance, if chlorine based flux is used, it will cause
pipe corrosion or, in particular, if the flux contains fluorine, it will
deteriorate the refrigerant oil.
