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.

SAFETY CONSIDERATIONS

The precautions listed here are divided into the following two types.
Both cover very important topics, so be sure to follow them carefully.

WARNING

If the warning is not observed, it may cause serious casualties.

CAUTION

If the caution is not observed, it may cause injury or damage to the
equipment.

Warning

■

The equipment is not intended for use in a potentially explosive
atmosphere.

■ Ask your dealer or qualified personnel to carry out installation
work. Do not install the machine by yourself.
Improper installation may result in water leakage, electric shocks
or fire.

■ Perform installation work in accordance with this installation
manual.
Improper installation may lead to water leakage, electric shocks
or fire.

■ When a unit is installed in a small room, it is necessary to take
measures so that the leaked refrigerant amount does not exceed
the limit even if it leaks. As for the measures to prevent the leak
from not exceeding the limit, please consult with your distributor.
If the leaked amount exceeds the limit, it may cause an oxygen
deficiency accident.

■ Be sure to use only the specified accessories and parts for
installation work.
Failure to use the specified parts may result in water leakage,
electric shocks, fire, or the unit falling.

■ Install the air conditioner on a foundation that can withstand its
weight.
Insufficient strength may result in the fall of equipment and
causing injury.

■ Carry out the specified installation work in consideration of
strong winds, typhoons, or earthquakes.
Improper installation work may result in accidents due to falling
of equipment.

■ Make certain that all electrical work is carried out by qualified
personnel according to the local laws and regulations and this
installation manual, using a separate circuit.
Insufficient capacity of the power supply circuit or improper
electrical construction may lead to electric shocks or fire.

■ Make sure that all wiring is secure, using the specified wires and
ensuring that external forces do not act on the terminal
connections or wires.
Incomplete connection or fixing may cause a fire.

■ When wiring between the indoor and outdoor units, and wiring
the power supply, form the wires so that the frontside panel can
be securely fastened.
If the frontside panel is not in place, overheat of the terminals,
electric shocks or a fire may be caused.

■ If refrigerant gas leaks during installation work, ventilate the area
immediately.
Toxic gas may be produced if refrigerant gas comes into contact
with fire.

■ After completing the installation work, check to make sure that
there is no leakage of refrigerant gas.
Toxic gas may be produced if refrigerant gas leaks into the room
and comes into contact with a source of fire, such as a fan
heater, stove or cooker.

■ Before touching electric terminal parts, turn off the power switch.

■ Live parts can be easily touched by accident.

Do never leave the unit unattended during installation or
servicing when the service panel is removed.

■ When planning to relocate former installed units, you must first
recover the refrigerant after the pumping-down operation. Refer
to chapter "Precaution for pumping-down operation" on page 10.

■ Do never directly touch any accidental leaking refrigerant. This
could result in severe wounds caused by frostbite.

Caution

BEFORE INSTALLATION

■ Ground the air conditioner.
Grounding resistance should be according to national
regulations
Do not connect the earth wire to gas or water pipes,
lightning conductor or telephone earth wire.
Incomplete grounding may cause electric shocks.

■ Gas pipe.

Ignition or explosion may occur if the gas leaks.

■ Water pipe.

Hard vinyl tubes are not effective grounds.

■ Lightning conductor or telephone ground wire.

Electric potential may rise abnormally if struck by a lightning
bolt.

■ Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may cause electric
shocks and fire.

■ Install drain piping according to this installation manual to
ensure good drainage, and insulate the pipe to prevent
condensation.
Improper drain piping may cause water leakage, and make the
furnitures get wet.

■ Install the indoor and outdoor units, power wire and connecting
wire at least 1 meter away from televisions or radios to prevent
image interference or noise.
(Depending on the radio waves, a distance of 1 meter may not
be sufficient to eliminate the noise.)

■ Do not install the air conditioner in places such as the following:

■ Where there is mist of mineral oil, oil spray or vapor for

example a kitchen.
Plastic parts may deteriorate, and cause them to fall out or

water to leak.

■ Where corrosive gas, such as sulfurous acid gas, is

produced.
Corrosion of copper pipes or soldered parts may cause the

refrigerant to leak.

■ Where there is machinery which emits electromagnetic

waves.
Electromagnetic waves may disturb the control system, and

cause malfunction of the equipment.

■ Where flammable gases may leak, where carbon fiber or

ignitable dust is suspended in the air or where volatile
flammables, such as thinner or gasoline, are handled.

Such gases may cause a fire.

■ Where the air contains high levels of salt such as that near

the ocean.

■ Where voltage fluctuates a lot, such as that in factories.

■ In vehicles or vessels.

■ Where acidic or alkaline vapour is present.

Since design pressure is 4.15 MPa or 41.5 bar, pipes of
larger wall thickness may be required. Refer to "Selection

of piping material" on page 4

Precautions for R410A

■ The refrigerant requires strict cautions for keeping the system
clean, dry and tight.

- Clean and dry
Foreign materials (including mineral oils or moisture) should be
prevented from getting mixed into the system.

- Tight
Read "Precautions on refrigerant piping" on page 5 carefully and
follow these procedures correctly.

■ Since R410A is a mixed refrigerant, the required additional
refrigerant must be charged in its liquid state. (If the refrigerant is
in state of gas, its composition changes and the system will not
work properly).

■ The connected indoor units must be indoor units designed
exclusively for R410A.

Installation

■ For installation of the indoor unit(s), refer to the indoor unit
installation manual.

■ Illustrations show a class 125 outdoor unit type. Other types also
follow this installation manual.

■ This outdoor unit requires the pipe branching kit (optional) when
used as the outdoor unit for the simultaneous operation system.
Refer to catalogues for details.

■ Never operate the unit without the thermistor (R3T), burning of
the compressor may result.

■ Be sure to confirm the model name and the serial no. of the
outer (front) plates when attaching/detaching the plates to avoid
mistakes.

■ When closing the service panels, take care that the tightening
torque does not exceed 4.1 N•m.

SELECTING INSTALLATION SITE

A

■ Make sure to provide for adequate measures in order
to prevent that the outdoor unit be used as a shelter
by small animals.

■ Small animals making contact with electrical parts can
cause malfunctions, smoke or fire. Please instruct the
customer to keep the area around the unit clean.

1 Select an installation site where the following conditions are

satisfied and that meets with your customer's approval.

- Places which are well-ventilated.

- Places where the unit does not bother next-door neighbours.

- Safe places which can withstand the unit's weight and
vibration and where the unit can be installed level.

- Places where there is no possibility of flammable gas or
product leak.

- Places where servicing space can be well ensured.

- Places where the indoor and outdoor units' piping and wiring
lengths come within the allowable ranges.

- Places where water leaking from the unit cannot cause
damage to the location (e.g. in case of a blocked drain pipe).

- Places where rain can be avoided as much as possible.

2 When installing the unit in a place exposed to strong wind, pay

special attention to the following.

Strong winds of 5 m/sec or more blowing against the outdoor
unit's air outlet causes short circuit (suction of discharge air),
and this may have the following consequences:

- Deterioration of the operational capacity.

- Frequent frost acceleration in heating operation.

- Disruption of operation due to rise of high pressure.

- When a strong wind blows continuously on the face of the
unit, the fan can start rotating very fast until it breaks.

Refer to the figures for installation of this unit in a place where
the wind direction can be foreseen.

■ Turn the air outlet side toward the building's wall, fence or
screen.

5 If you install the unit on a frame, please install a waterproof plate

within 150 mm of the underside of the unit in order to prevent the
invasion of water from the lower direction.

6 When installing the unit in a place frequently exposed to snow,

pay special attention to the following:

- Elevate the foundation as high as possible.

- Remove the rear suction grille to prevent snow from
accumulating on the rear fins.

7 If you install the unit on a building frame,

please install a waterproof plate (within
150 mm of the underside of the unit) or
use a drain plug kit (option) in order to
avoid the drainwater dripping.

PRECAUTIONS ON INSTALLATION

■ Check the strength and level of the installation ground so that
the unit will not cause any operating vibration or noise after
installation.

■ In accordance with the foundation drawing in the figure, fix the
unit securely by means of the foundation bolts. (Prepare four
sets of M12 foundation bolts, nuts and washers each which are
available on the market.)

■ It is best to screw in the foundation bolts until their length is
20 mm from the foundation surface.
