2. General safety precautions

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

DANGER: ELECTRICAL SHOCK

Switch off all power supply before removing the electrical
component box service panel or before making any
connections or touching electrical parts.

Do not touch any switch with wet fingers. Touching a
switch with wet fingers can cause electrical shock. Before
touching electrical parts, turn off all applicable power
supply.

To avoid electric shock, be sure to disconnect the power
supply 1 minute or more before servicing the electrical
parts. Even after 1 minute, always measure the voltage at
the terminals of the main terminal, main circuit capacitors
or electrical parts and, before touching, be sure that those
voltages are 50 V DC or less.

When service panels are removed, live parts can easily be
touched by accident. Never leave the unit unattended
during installation or servicing when the service panel is
removed.

DANGER: DO NOT TOUCH PIPING AND INTERNAL
PARTS

Do not touch the refrigerant piping, water piping or internal
parts during and immediately after operation. The piping
and internal parts may be hot or cold depending on the
working condition of the unit.

Your hand may suffer burns or frostbite if you touch the
piping or internal parts. To avoid injury, give the piping and
internal parts time to return to normal temperature or, if you
must touch them, be sure to wear protective gloves.

Also, at least, following information shall be provided at an accessible
place of the system:

 Instructions for shutting down the system in case of an

emergency.

 Name and address of fire department, police and hospital.
 Name, address and day and night telephone numbers for

obtaining service.

In Europe, EN 378 provides the necessary guidance for this logbook.

WARNING

 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.

 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.

 Do not allow a child to mount on the outdoor unit or avoid placing

any object on the unit.
Falling or tumbling may result in injury.

 Do not touch any refrigerant which has leaked out of refrigerant

piping connections.
This may result in frostbite.

 Sound pressure is less than 70 dB(A).
 The appliance is not intended for use by persons, including

children, with reduced physical, sensory or mental capabilities,
or lack of experience and knowledge, unless they have been
given supervision or instruction concerning use of the appliance
by a person responsible for their safety. Children must be

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
furniture 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 rinse the outdoor unit.

This may cause electric shocks or fire.

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

 Where there is mist of mineral oil, oil spray or vapour for

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

 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.

4.3. Handling

As shown in the figure, bring the unit slowly by grabbing the left and
right grips.

Place your hands on the corner instead of holding the suction inlet in
the side of the casing, otherwise the casing could be deformed.

CAUTION

Take care not to let hands or objects come in contact with
rear fins.

5. Selecting installation site

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.

3.4. Technical and electrical specifications

Refer to the Engineering Data Book for the complete list of
specifications.

4. Before installation

Since design pressure is 4.0 MPa or 40 bar, pipes of larger
wall thickness may be required. Refer to paragraph
"8.1. Selection of piping material" on page 7.

4.1. 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 "9. Precautions on refrigerant piping" on page 7 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.

4.2. Installation

 For installation of the indoor unit(s), refer to the indoor unit

installation manual.

 Never operate the air conditioner with the discharge pipe

thermistor (R2T), suction pipe thermistor (R3T) and pressure
sensors (S1NPH, S1NPL) removed. Such operation may burn
out the compressor.

WARNING

 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 lengths of piping and wiring for indoor units and
outdoor units are 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 the 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.
