WARNING
•
Ask your dealer or qualifies personnel to carry out installation work.
Do not attempt to install the air conditioner yourself. Improper
installation may result in water leakage, electric shocks or fire.
•
Consult your local regarding what to do in case of refrigerant
leakage, when the air conditioner is to be installed in a small room,
it is necessary to take proper measures so that the amount of any
leaked refrigerant does not exceed the concentration limit in the
event of leakage. Otherwise, this may lead to an accident due to
oxygen depletion.
•
Install the air conditioner in accordance with the instructions in this
installation manual.
Improper installation may result in water leakage, electric shocks
or fire.
•
When installing the unit in a small room, take measures against to
keep refrigerant concentration from exceeding allowable safety
limits in the event of refrigerant leakage.
Contact the place of purchase for more information. Excessive
refrigerant in a closed ambient can lead to oxygen deficiency.
•
Be sure to use only the specified accessories and parts for
installation work.
Failure to use the specified parts may result in the unit falling,
water leakage, electric shocks or fire.
•
Install the air conditioner on a foundation strong enough to
withstand the weight of the unit.
A foundation of insufficient strength may result in the equipment
falling and causing injury.
•
Carry out the specified installation work after taking into account
strong winds, typhoons or earthquakes.
Failure to do so during installation work may result in the unit falling
and causing accidents.
•
Make sure that a separate power supply circuit is provided for this
unit and that all electrical work is carried out by qualified personnel
according to local laws and regulations and this installation manual.
An insufficient power supply capacity or improper electrical
construction may lead to electric shocks or fire.
•
Make sure that all wiring is secured, the specified wires are used,
and that there is no strain on the terminal connections or wires.
Improper connections or securing of wires may result in abnormal
heat build-up or fire.
•
When wiring the power supply and connecting the remote controller
wiring and transmission wiring, position the wires so that the
EL.COMPO.BOX lid can be securely fastened.
Improper positioning of the EL.COMPO.BOX lid may result in
electric shocks, fire or the terminals overheating.
•
If refrigerant gas leaks during installation, ventilate the area
immediately.
Toxic gas may be produced if the refrigerant comes into contact
with fire.
•
After completing installation, check for refrigerant gas leakage.
Toxic gas may be produced if the refrigerant gas leaks into the
room and comes into contact with a source of fire, such as a fan
heater, stove or cooker.
•
Do not directly touch refrigerant that has leaked from refrigerant
p
i
pes or other areas, as there is a danger of frostbite.
•
Be sure to switch off the unit before touching any electrical parts.
•
Do not allow children to climb on the outdoor unit and avoid placing
objects on the unit.
Injury may result if the unit becomes loose and falls.
•
Be sure to earth the air conditioner.
Do not earth the unit to a utility pipe, lightning conductor
or telephone earth lead.
Imperfect earthing may result in electric shocks or fire.
A high surge current from lightning or other sources may cause
damage to the air conditioner.
•
Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may result in electric
shocks or fire.
•
While following the instructions in this installation manual, install
drain piping to ensure proper drainage and insulate piping to prevent
condensation.
Improper drain piping may result in indoor water leakage and
property damage.
•
Install the indoor and outdoor units, power cord and connecting
wires at least 1 meter away from televisions or radios to prevent
picture interference and noise.
(Depending on the incoming signal strength, a distance of 1 meter
may not be sufficient to eliminate noise.)
•
Remote controller (wireless kit) transmitting distance can be shorter
than expected in rooms with electronic fluorescent lamps (inverter
or rapid start types).
Install the indoor unit as far away from fluorescent lamps as possible.
•
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.
CAUTION
VRV System use R410A refrigerant.
•
Do not install the air conditioner in the following locations:
1. Where there is a high concentration of mineral oil spray or
vapour (e.g. a kitchen).
Plastic parts will deteriorate, parts may fall off and water
leakage could result.
2. Where corrosive gas, such as sulphurous acid gas, is produced.
Corroding of copper pipes or soldered parts may result in
refrigerant leakage.
3. Near machinery emitting electromagnetic radiation.
Electromagnetic radiation may disturb the operation of the
control system and result in a malfunction of the unit.
4. Where flammable gas may leak, where there is carbon fibre or
ignitable dust suspensions in the air, or where volatile
flammables such as paint thinner or gasoline are handled.
Operating the unit in such conditions may result in fire.
•
In a domestic environment this product may cause radio
interference in which case the user may be required to take
adequate measures.
2.2 Special notice of product
2.3 Disposal requirements
•
The refrigerant R410A requires that strict precautions be
observed for keeping the system clean, dry and tightly sealed.
Read the chapter “REFRIGERANT PIPING” carefully and follow
these procedures correctly.
A. Clean and dry
Strict measures must be taken to keep impurities (including
SUNISO oil and other mineral oils as well as moisture) out of
the system.
B. Tight sealed
Take care to keep the system tight when installing.
R410A contains no chlorine, does not destroy the ozone layer
and so does not reduce the earth’s protection against harmful
ultraviolet radiation.
R410A will contribute only slightly to the greenhouse effect if
released into the atmosphere.
Since design pressure is 4.0 MPa or 40 bar (for R407C units : 3.3 MPa
or 33 bar) the thickness of pipes must be greater than previously.
Since R410A is a mixed refrigerant, the required additional refrigerant
must be charged in its liquid state. (If the system is charged with
refrigerant in its gaseous state, due to compositions change, the system
will not function normally). The indoor units is designed for R410A use.
See the catalogue for indoor unit models that can be connected.
(Normal operation is not possible when connecting units that are
originally designed for other refrigerants)
[DESIGN PRESSURE]
Dismantling of the unit, treatment of the refrigerant, of oil and of other
parts must be done in accordance with relevant local and national
legislation.
