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.

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.

■ 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.
See figure 1

1 Drain hose
2 Metal clamp
3 Washer for hanger bracket
4 Paper pattern for installation
5 Srews (M5) for paper pattern for installation
6 Insulation for gas pipe fitting
7 Insulation for liquid pipe fitting
8 Large sealing pad

9 Small sealing pad
10 Sealing material
11 Installation manual and operation manual

BEFORE INSTALLATION

■ When moving the unit while removing it from the carton box, be
sure to lift it by holding on to the four lifting lugs without exerting
any pressure on other parts, especially on the swing flap, the
refrigerant piping, drain piping, and other resin parts.

■ 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.

■ Especially, do not unfasten the packing case (top) guarding the
switch box until suspending 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.

Installation 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.

It may result in insufficient cooling.

Are refrigerant piping length and additional refrigerant charge
noted down?

The refrigerant charge in the system might not be clear.

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 "Field setting" on page 7. (See

figure 2) ( : 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 6 (: air flow
direction)

1 Air inlet
2 Air outlet

NOTE

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

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.

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.)

•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

Install this unit where the height of bottom panel is more than

2.5 m so that the user cannot easily touch.

PREPARATIONS BEFORE INSTALLATION

1 Relation of ceiling opening to unit and suspension bolt

position. (See figure 7)

1 Decoration panel dimensions
2 Ceiling opening dimensions
3 Indoor unit dimensions
4 Suspension bolt pitch dimensions
5 Refrigerant piping
6 Suspension bolt (x4)
7 False ceiling
8 Hanger bracket

NOTE

2 Make the ceiling opening needed for installation where

Installation is possible with a ceiling dimension of
660 mm (marked with *). However, to achieve a ceiling­panel overlapping dimension of 20 mm, the spacing
between the ceiling and the unit should be 45 mm or
less. If the spacing between ceiling and the unit is over
45 mm, attach sealing material in the part marked
or recover the ceiling.

(See figure 3)

applicable. (For existing ceilings.)

- Refer to the paper pattern for installation for the ceiling
opening dimensions.

- Create the ceiling opening required for installation. From the
side of the opening to the casing outlet, implement the
refrigerant and drain piping and wiring for remote controller
(unnecessary for wireless type). Refer to each piping or
wiring section.

- After making an opening in the ceiling, it may be necessary
to reinforce ceiling beams to keep the ceiling level and to
prevent it from vibrating. Consult the builder for details.

INDOOR UNIT INSTALLATION

When installing optional accessories (except for the decoration
panel), read also the installation manual of the optional accessories.
Depending on the field conditions, it may be easier to install optional
accessories before the indoor unit is installed. However, for existing
ceilings, install fresh air inlet component kit and branch duct before
installing the unit.

1 Install the indoor unit temporarily.

- Attach the hanger bracket to the suspension bolt. Be sure to
fix it securely by using a nut and washer from the upper and
lower sides of the hanger bracket.

- Securing the hanger bracket (See figure 5)

1 Nut (field supply)
2 Hanger bracket
3 Washer (supplied with the unit)
4 Tighten (double nut)

2 Fix the paper pattern for installation. (For new ceilings only.)

- The paper pattern for installation corresponds with the
measurements of the ceiling opening. Consult the builder for
details.

- The centre of the ceiling opening is indicated on the paper
pattern for installation. The centre of the unit is indicated on
the paper pattern for installation.

- After removing the packaging material from the paper pattern
for installation, attach the paper pattern for installation to the
unit with the attached screws as shown in figure 8.

1 Paper pattern for installation (supplied with the unit)
2 Screws (supplied with the unit)

3 Adjust the unit to the right position for installation.

(See "Preparations before installation" on page 2.)

4 Check if the unit is horizontally levelled.

- Do not install the unit tilted. The indoor unit is equipped with a
built-in drain pump and float switch. (If the unit is tilted
against condensate flow, the float switch may malfunction
and cause water to drip.)

- Check if the unit is levelled at all four corners with a water
level or a water-filled vinyl tube as shown in figure 9.

2 Vinyl tube

REFRIGERANT PIPING WORK

All field piping must be provided by a licensed refrigeration
technician and must comply with the relevant local and
national codes.

■ For refrigerant piping of outdoor unit, refer to the installation
manual supplied with the outdoor unit.

■ Execute heat insulation work completely on both sides of the
gas piping and the liquid piping. Otherwise, this can sometimes
result in water leakage.
(When using a heat pump, the temperature of the gas piping can

reach up to approximately 120°C
sufficiently resistant.)

■ Also, in cases where the temperature and humidity of the
refrigerant piping sections might exceed 30°C or RH 80%,
reinforce the refrigerant insulation (20 mm or thicker).
Condensation may form on the surface of the insulating
material.

■ Before rigging tubes, check which type of refrigerant is used.

■ Use a pipe cutter and flare suitable for the used refrigerant.

■ Apply ether oil or ester oil around the flare portions before

connecting.

■ To prevent dust, moisture or other foreign matter from infiltrating
the tube, either pinch the end, or cover it with tape.

■ Use copper alloy seamless pipes (ISO 1337).

■ The outdoor unit is charged with refrigerant.

■ Be sure to use both a spanner and torque wrench together when

connecting or disconnecting pipes to/from the unit.

1 Torque wrench
2 Flare nut
3 Piping union
4 Spanner

■ Do not mix anything other than the specified refrigerant, such as
air, etc.., inside the refrigerant circuit.

■ Refer to the table below for the dimensions of flare nuts and the
appropriate tightening torque. (Overtightening may damage the
flare and cause leaks.)

Not recommended but in case of emergency.

You must use a torque wrench but if you are obliged to
install the unit without a torque wrench, you may follow
the installation method mentioned below.

After the work is finished, make sure to check that
there is no gas leak.

When you keep on tightening the flare nut with a
spanner, there is a point where the tightening torque
suddenly increases. From that position, further tighten
the flare nut within the angle shown below.

4 turns before tightening firmly.

■ Check the pipe connector for gas leaks, then insulate it as
shown in figure 10.

1 Liquid pipe
2 Gas pipe
3 Insulation for fitting of liquid line (supplied with the unit)
4 Insulation for fitting of gas line (supplied with the unit)
5 Clamps (use 2 clamps per insulation)
6 Small sealing pad (supplied with the unit)

■ Wrap the sealing pad only around the insulation for the joints on
the gas piping side.

Be sure to insulate any field piping all the way to the
piping connection inside the unit. Any exposed piping
may cause condensation or burns if touched.

■ If the refrigerant gas leaks during the work, ventilate the area. A
toxic gas is emitted by the refrigerant gas being exposed to a
fire.

■ Finally make sure there is no refrigerant gas leak. A toxic gas
may be released by the refrigerant gas leaking indoor and being
exposed to flames from an area heater, cooking stove, etc.

DRAIN PIPING WORK

Rig the drain piping as shown in figure and take measures against
condensation. Improperly rigged piping could lead to leaks and
eventually wet furniture and belongings.

1 Install the drain pipes.

•Keep piping as short as possible and slope it downwards so that

air may not remain trapped inside the pipe.

•Keep pipe size equal to or greater than that of the connecting

(PVC pipe, nominal diameter 20 mm, outside diameter

pipe

26 mm).

• Insert the drain hose into the drain socket up to the base, and

tighten the clamp securely within the portion of a grey tape.

• Tighten the clamp until the screw head is less then 4 mm from the

hose.

Precautions

■ Install the drain raising pipes at a height of less than 545 mm.

■ Install the drain raising pipes at a right angle to the indoor unit

and no more than 300 mm from the unit.

NOTE

■ The incline of attached drain hose should be
75 mm or less so that the drain socket does not
have to stand additional force.

■ To ensure a downward slope of 1:100, install
hanging bars every 1 to 1.5 m.

■ If unifying multiple drain pipes, install the pipes as
shown in figure 11. Select converging drain pipes
whose gauge is suitable for the operating capacity
of the unit.

1 After piping work is finished, check if drainage flows

smoothly.

■ Open the water inlet lid, add approximately 2 l of water
gradually and check the drainage flow.

Method of adding water. See figure 12.

1 Drain pipe
2 Service drain outlet with rubber plug. Use this outlet to drain

water from the drain pan.

3 Plastic container for pouring

■ Drain piping connections

Do not connect the drain piping directly to sewage pipes
that smell of ammonia. The ammonia in the sewage might
enter the indoor unit through the drain pipes and corrode
the heat exchanger.

■ Keep in mind that it will become the cause of getting
drain pipe blocked if water collects on drain pipe.

When electric wiring work is finished

Check drainage flow during COOL running, explained in "Test

operation" on page 7.

PRECAUTIONS

1 Observe the notes mentioned below when wiring to the power

supply terminal board.

■ Do not connect wires of different gauge to the same power
supply terminal. (Looseness in the connection may cause
overheating.)

■ When connecting wires of the same gauge, connect them
according to the figure.

Use the specified electric wire. Connect the wire securely to the
terminal. Lock the wire down without applying excessive force to
the terminal. (Tightening torque: 1.31 N•m±10%).

2 Keep total current of crossover wiring between indoor units less

than 12 A. Branch the line outside the terminal board of the unit
in accordance with electrical equipment standards, when using
two power wiring of a gauge greater than 2 mm

2

(Ø1.6).

The branch must be sheathed in order to provide an equal or
greater degree of insulation as power supply wiring itself.

3 Do not connect wires of different gauge to the same grounding

terminal. Looseness in the connection may deteriorate the
protection.

4 Remote controller cords and wires connecting the units should

be located at least 50 mm away from power supply wiring. Not
following this guideline may result in malfunction due to
electrical noise.

5 For the remote controller wiring, refer to the "Installation manual

of the remote controller" supplied with the remote controller.

6 Never connect the power supply wiring to the terminal board for

transmission wiring. This mistake could damage the entire system.

WIRING EXAMPLE

For the wiring of outdoor units, refer to the installation manual
attached to the outdoor units.

Confirm the system type:

■ Pair type or multi system: 1 remote controller controls 1 indoor
unit (standard system). (See figure 18)

■ Multi system: 1 to 4 indoor units connected to 1 outdoor unit.
The indoor unit is controlled by a remote controller connected to
each indoor unit. However, the group control is not expected.

(See figure 19)

■ Group control: 1 remote controller controls up to 16 indoor
units (All indoor units operate according to the remote
controller). (See figure 20)

■ 2 remote controller control: 2 remote controllers control 1
indoor unit. (See figure 21)

NOTE

PRECAUTIONS

1 All transmission wiring except for the remote controller wiring is

It is not necessary to designate indoor unit address
when using group control. The address is auto­matically set when the power is activated.

polarized and must match the terminal symbol.

7 Use only specified wires and tightly connect wires to the

terminals. Be careful that wires do not place external stress on
the terminals. Keep wiring in neat order so that they do not
obstruct other equipment such as popping open the service
cover. Make sure the cover closes tight. Incomplete connections
could result in overheating, and in the worst case, electric shock
or fire.

2 In case of group control, perform the remote controller wiring to

the master unit when connecting to the simultaneous operation
system (wiring to the slave unit is unnecessary).

3 For group control remote controller, choose the remote

controller that suits the indoor unit which has the most functions
(as attached swing flap).

4 Do not ground the equipment on gas pipes, water pipes,

lightning rods or crossground with telephones. Improper ground­ing could result in electric shock.

5 In case a shielding wire is to be used, connect a shielded portion

with the of a remote controller terminal board. (Also, connect the
ground for the remote control to a grounded metal part.)
