operation manual

INSTALLING THE UNIT

READ THESE INSTRUCTIONS CAREFULLY BEFORE
INSTALLATION.

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 UNCERTAINTY ARISES ABOUT THE INSTALLATION
PROCEDURES OR USE, ALWAYS CONTACT YOUR
DAIKIN DEALER FOR ADVICE AND INFORMATION.

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.

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 can be

found. (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.

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

Installation and operation manual

Optional accessories

Refer to catalogues and technical literature for selecting the remote
controller, and install it in an appropriate place.

The unit may drop, vibrate or make noise.

Is the gas leak test finished?

It may result in insufficient cooling.

Is the unit fully insulated?

Condensate water may drip.

Does drainage flow smoothly?

Condensate water may drip.

Does the power supply voltage correspond to that shown on the
name plate?

The unit may malfunction or components may burn out.

Are wiring and piping correct?

The unit may malfunction or components may burn out.

Is the unit safely grounded?

Dangerous at electric leakage.

Is the wiring size according to specifications?

The unit may malfunction or components may burn out.

Is nothing blocking the air outlet or inlet of either the indoor or
outdoor units?

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.
This to avoid confusion for future maintenance and serving of
the installation.

Notes to the installer

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

SELECTING INSTALLATION SITE (See figure 1 and 4)

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
interference in those electrical appliances.

(Electric noise may be generated depending on the conditions
under which the electric wave is generated, even if 1 meter is
kept.)

•Never place anything under the indoor unit that you don't want to

get wet. The unit may sweat when the humidity is over 80% or
when the drain outlet is clogged.

•Never place other heating equipment directly beneath the indoor

unit. Subject to deformation caused by heat.

• The unit should be installed at least 2.5 m from the floor.

2. 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.

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.

2. Do not connect wires of different gauge to the same grounding

terminal. Looseness in the connection may deteriorate the
protection.

3. 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.

4. For the remote controller wiring, refer to the "Installation manual of

the remote controller" supplied with the remote controller.

NOTE

The customer has the ability to select the remote
controller thermistor.

5. Never connect the power supply wiring to the terminal board for

transmission wiring. This mistake could damage the entire system.

6. 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 switch box cover. Make sure
the cover closes tight. Incomplete connections could result in
overheating, and in the worst case, electric shock or fire.

WIRING EXAMPLE

■ Fit the power supply wiring of each system with a switch and
fuse as shown in figure 7, 9 and 10.

after DEFROST OPERATION.
Moisture generated by DEFROST becomes steam and exits.

Noise of air conditioners

■ A continuous low "hissing" sound is heard when the system is in
COOLING or DEFROST OPERATION.
This is the sound of refrigerant gas flowing through both indoor
and outdoor units.

■ A "hissing" sound which is heard at the start or immediately after
the stop of operation or which is heard at the start or
immediately after the stop of DEFROST OPERATION.
This is the noise of refrigerant caused by flow stop and flow
change.

■ A "squeaking" sound is heard when the system is in operation or
after the stop of operation.
Expansion and contraction of plastic parts caused by
temperature change makes this noise.

Dust from the units

■ Dust may blow out from the unit after starting operation from
long resting time. Dust absorbed by the unit blows out.
