READ THESE INSTRUCTIONS CAREFULLY BEFORE
INSTALLATION. KEEP THIS MANUAL IN A HANDY
PLACE FOR FUTURE REFERENCE.

IMPROPER INSTALLATION OR ATTACHMENT OF
EQUIPMENT OR ACCESSORIES COULD RESULT IN
ELECTRIC SHOCK, SHORT-CIRCUIT, LEAKS, FIRE OR
OTHER DAMAGE TO THE EQUIPMENT. BE SURE ONLY
TO USE ACCESSORIES MADE BY DAIKIN WHICH ARE
SPECIFICALLY DESIGNED FOR USE WITH THE
EQUIPMENT AND HAVE THEM INSTALLED BY A
PROFESSIONAL.

IF UNSURE OF INSTALLATION PROCEDURES OR USE,
ALWAYS CONTACT YOUR DAIKIN DEALER FOR
ADVICE AND INFORMATION.

■ When selecting the installation site, use the supplied paper
pattern for installation.

■ Do not install accessories on the casing directly. Drilling holes in the
casing may damage electrical wires and consequently cause fire.

Accessories

Check if the following accessories are included with your unit.

Also used as packing

Clamp

1 piece

Screws M5

For paper pattern

4 pieces.

Insulation for fitting 1 each

for gas pipe

Paper pattern for

Other: installation and
operation manual

Optional accessories

■ There are two types of remote controllers: wired and wireless.
Select a remote controller according to customers request and
install in an appropriate place.
Refer to catalogues and technical literature for selecting a
suitable remote controller.

■ A decoration panel is also required for this indoor unit.

BEFORE INSTALLATION

■ Leave the unit inside its packaging until you reach the
installation site. Where unpacking is unavoidable, use a sling of
soft material or protective plates together with a rope when
lifting, this to avoid damage or scratches to the unit.

■ Refer to the installation manual of the outdoor unit for items not
described in this manual.

■ Caution concerning refrigerant series R410A:
The connectable outdoor units must be designed exclusively for

R410A.

■ Do not place objects in direct proximity of the outdoor unit and
do not let leaves and other debris accumulate around the unit.
Leaves are a hotbed for small animals which can enter the unit.
Once in the unit, such animals can cause malfunctions, smoke
or fire when making contact with electrical parts.

Precautions

■ Do not install or operate the unit in rooms mentioned below.

• Places with mineral oil, or filled with oil vapour or spray like in

kitchens. (Plastic parts may deteriorate.)

• Where corrosive gas like sulphurous gas exists. (Copper tubing

and brazed spots may corrode.)

• Where volatile flammable gas like thinner or gasoline is used.

• Where machines generating electromagnetic waves exist.

(Control system may malfunction.)

• Where the air contains high levels of salt such as air near the

ocean and where voltage fluctuates a lot (e.g. in factories). Also
in vehicles or vessels.

Notes to the installer

■ Read this manual carefully to ensure correct installation. Be

sure to instruct the customer how to properly operate the system
and show him/her the enclosed operation manual.

■ Explain to the customer what system is installed on the site. Be

sure to fill out the appropriate installation specifications in the
chapter "What to do before operation" of the outdoor unit
operation manual.

NOTE

Leave 200 mm or more space where marked with *; on
sides where the air outlet is closed.

Model H

FXFQ20~63 ≥240
FXFQ80~125 ≥298

SELECTING INSTALLATION SITE

When the conditions in the ceiling are exceeding 30°C and a relative
humidity of 80%, or when fresh air is inducted into the ceiling, an
additional insulation is required (minimum 10 mm thickness,
polyethylene foam).

For this unit you can select different air flow directions. It is necessary
to purchase an optional blocking pad kit to discharge the air in 2 or 3
directions.

1 Select an installation site where the following conditions

are fulfilled and that meets your customer's approval.

• Where optimum air distribution can be ensured.

• Where nothing blocks air passage.

• Where condensate water can be properly drained.

• Where the false ceiling is not noticeably on an incline.

• Where sufficient clearance for maintenance and service can be
ensured.

• Where piping between indoor and outdoor units is possible within
the allowable limit. (Refer to the installation manual of the outdoor
unit.)

• This is a class A product. In a domestic environment this product
may cause radio interference in which case the user may be
required to take adequate measures.

•Keep indoor unit, outdoor unit, power supply wiring and
transmission wiring at least 1 meter away from televisions and
radios. This is to prevent image interference and noise in those
electrical appliances.
(Noise may be generated depending on the conditions under
which the electric wave is generated, even if 1 meter is kept.)

2 Ceiling height

This indoor unit may be installed on ceilings up to 3.5 m in
height (for 80~125 units: 4.2 m). However, it becomes necessary
to make field settings by the remote controller when installing
the unit at a height over 2.7 m (for 80~125 units: 3.2 m). To avoid
accidental touching, it is recommended to install the unit higher
than 2.5 m.
Refer to the chapter "Field setting" and to the decoration panel
installation manual.

3 Air flow directions

Select the air flow directions best suited to the room and point of
installation. (For air discharge in 2 or 3 directions, it is necessary
to make field settings by means of the remote controller and to
close the air outlet(s). Refer to the installation manual of the
optional blocking pad kit and to the chapter "Field setting".) (See

figure 1 ( = air flow direction))

1 Air discharge in 4 directions
2 Air discharge in 3 directions
3 Air discharge in 2 directions

4 Use suspension bolts for installation. Check whether the

ceiling is strong enough to support the weight of the indoor
unit. If there is a risk, reinforce the ceiling before installing
the unit.

(The installation pitch is marked on the paper pattern for
installation. Refer to it to check for points requiring reinforcing.)
Space required for installation see figure 2 ( = air flow
direction)

1 Air discharge
2 Air inlet

3 Hanger bracket
4 False ceiling
5 Suspension bolt pitch
6 Indoor unit
7 Ceiling opening
8 Decoration panel

■ Installation is possible when opening dimensions are as follows.
When installing the unit within the frame for fixing ceiling
materials. (See figure 4)

1 Dimensions inside frame
2 Opening dimension inside the frame for ceiling
3 Frame
4 Ceiling material
5 Ceiling opening dimension
6 Ceiling-panel overlapping dimension

NOTE

2. Make the ceiling opening needed for installation where
applicable. (For existing ceilings.)

• Refer to the paper pattern for installation for the ceiling opening

• Create the ceiling opening required for installation. From the side

• After making an opening in the ceiling, it may be necessary to

3. Install the suspension bolts. (use either a W3/8 or M10 size bolt.)

Use anchors for existing ceilings, and a sunken insert, sunken
anchors or other field supplied parts for new ceilings to reinforce the
ceiling in order to bear the weight of the unit. Adjust clearance from
the ceiling before proceeding further.

Installation example see figure 5.

1 Ceiling slab
2 Anchor
3 Long nut or turn-buckle
4 Suspension bolt
5 False ceiling

NOTE

Installation is possible with a ceiling dimension of
910 mm (marked with*). However, to achieve a ceiling­panel overlapping dimension of 20 mm, the spacing
between the ceiling and the unit should be 35 mm or
less. If the spacing between ceiling and the unit is over
35 mm, attach ceiling material to the part or recover
the ceiling.

of the opening to the casing outlet, implement the refrigerant and
drain piping and wiring for remote controller (unnecessary for
wireless type) and indoor-outdoor unit casing outlet. Refer to
each piping or wiring section.

reinforce ceiling beams to keep the ceiling level and to prevent it
from vibrating. Consult the builder for details.
