2 Specific installer safety instructions
Always observe the following safety instructions and regulations.
Unit installation (see “5 Unit installation” 4[ 4])
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.

FTXTA30B2V1B(W)(B) Daikin room air conditioner 3P482320-12U 2021.03
WARNING The appliance shall be stored so as to prevent mechanical damage and
in a well-ventilated room without continuously operating ignition sources
(e.g. open flames, an operating gas appliance, or an operating electric
heater). The room size shall be as specified in the General safety precaution.
CAUTION For walls containing a metal frame or a metal board, use a wall
embedded pipe and wall cover in the feed-through hole to prevent possible
heat, electrical shock, or fire.
Piping installation (see “6 Piping installation” 4[ 6])
CAUTION Piping and joints of a split system shall be made with permanent
joints when inside an occupied space except joints directly connecting the
piping to the indoor units.
DANGER: RISK OF BURNING/SCALDING
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. NEVER install a drier to this
R32 unit to guarantee its lifetime. The drying material may dissolve and
damage the system.
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.
Electrical installation (see “7 Electrical installation” 4[ 7])
DANGER: RISK OF ELECTROCUTION
WARNING ALWAYS use multicore cable for power supply cables.
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.
3 About the box
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 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.

INFORMATION The sound pressure level is less than 70 dBA.
Air flow. Make sure nothing blocks the air flow. Drainage. Make sure
condensation water can be evacuated
properly.
Wall insulation. When conditions in the wall exceed 30°C and a relative
humidity of 80%, or when fresh air is inducted into the wall, then additional
insulation is required (minimum 10 mm thickness, polyethylene foam).
Wall strength. Check whether the wall or the floor is strong enough to support
the weight of the unit. If there is a risk, reinforce the wall or the floor
before installing the unit.
Spacing. Install the unit at least 1.8 m from the floor and keep the following
requirements in mind for distances from the walls and the ceiling:

5.2.3 To remove the pipe port cover
INFORMATION To connect the piping on right-side, right-bottom, left-side or
left-bottom, the pipe port cover MUST be removed. 1 Cut off the pipe port
cover from inside the front grille using a coping saw.
1 Remove the insulation fixing screw on the right side and remove the drain
hose.
2 Remove the drain plug on the left side and attach it to the right side.
NOTICE
Do NOT apply lubricating oil (refrigerant oil) to the drain plug when
inserting it. The drain plug may deteriorate and cause drain leakage from the
plug.
3 Insert the drain hose on the left side and do not forget to tighten it with
the fixing screw; otherwise water leakage may occur.
2 Remove any burrs along the cut section using a half round needle file.
NOTICE Do NOT use nippers to remove the pipe port cover, as this would damage
the front grille.
5.3 Connecting the drain piping
5.3.1 To connect the piping on right side, rightback, or right-bottom
INFORMATION The factory default is right-side piping. For left-side piping,
remove the piping from the right side and install it on the left side. 1

FTXTA30B2V1B(W)(B) Daikin room air conditioner 3P482320-12U 2021.03
NOTICE
The piping and other pressure-containing parts shall be suitable for
refrigerant. Use phosphoric acid deoxidised seamless copper for refrigerant.
Foreign materials inside pipes (including oils for fabrication) must be 30
mg/10 m.
Refrigerant piping diameter
Use the same diameters as the connections on the outdoor units:
Liquid piping Ø6.4 mm

Daikin Business Portal (authentication required). The general commissioning
checklist is complementary to the instructions in this chapter and can be used
as a guideline and reporting template during the commissioning and hand-over
to the user.
NOTICE ALWAYS operate the unit with thermistors and/or pressure
sensors/switches. If NOT, burning of the compressor might be the result.
10.1 Checklist before commissioning
After the installation of the unit, first check the items listed below. Once
all checks are fulfilled, the unit must be closed. Power-up the unit after it
is closed.
You read the complete installation instructions, as described in the installer
reference guide. The indoor units are properly mounted.
The outdoor unit is properly mounted.
Air inlet/outlet Check that the air inlet and outlet of the unit is NOT
obstructed by paper sheets, cardboard, or any other material. There are NO
missing phases or reversed phases.
The refrigerant pipes (gas and liquid) are thermally insulated. Drainage Make
sure drainage flows smoothly. Possible consequence: Condensate water might
drip. The system is properly earthed and the earth terminals are tightened.
The fuses or locally installed protection devices are installed according to
this document, and have NOT been bypassed. The power supply voltage matches
the voltage on the identification label of the unit. The specified wires are
used for the interconnection cable. The indoor unit receives the signals of
the user interface.
There are NO loose connections or damaged electrical components in the switch
box. The insulation resistance of the compressor is OK.
There are NO damaged components or squeezed pipes on the inside of the indoor
and outdoor units. There are NO refrigerant leaks.
