Meaning of warning and caution symbols
WARNING
............... Failure to observe a warning may result in death, injury or damage to the equipment.
CAUTION
................ Failure to observe a caution may result in injury or damage to the equipment.
WARNING
•
Ask your Dealer or qualified personnel to carry out installation work. Do not try to install the machine yourself.
Improper installation may result in water leakage, electric shock of fire.
•
Perform installation work in accordance with this installation manual.
Improper installation may result in water leakage, electrical shock or fire.
•
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 shock, fire or the unit failing.
•
Install the conditioner on a structure strong enough to withstand the weight of the unit.
A structure of insufficient strength may result in the equipment falling and causing injuries.
•
Carry out the specified installation work after taking into account strong winds, typhoons or earthquakes.
Improper installation work may result in the equipment falling and causing accidents.
•
Make sure that a separate power supply circuit is provided for this unit and that all electrical work carried out by qualified personnel
according to local laws, 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 no external forces act on the terminal connection or wires.
Improper connections or installation may result in fire.
•
When wiring the power supply and connecting the wiring between the indoor and outdoor units, position the wires so that the switch box
cover can be securely fastened.
Improper positioning of the switch box cover may result in electric shock, fire or the terminals overheating.
•
If the refrigerant gas leaks during installation, ventilate the area immediately.
Toxic gas may be produced if the refrigerant gas comes into contact with fire.
•
After completing the installation work, check that the refrigerant gas does not leak.
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.
•
Before obtaining access to the terminals and electrical parts, all supply circuits must be disconnected.
•
Do not install the indoor unit or remote controller where they may be exposed to rain or moisture.
Water or other fluids on the electrical components may result in fire or electric shock.
•
Earth the air conditioner. Do not connect the earth wire to gas or water pipes, a lightning conductor or a telephone ground wire.
Incomplete earthing may result in electric shock.
•
Be sure to install an earth leakage breaker. Failure to install an earth leakage breaker may result in electric shock.
•
Do not install the indoor unit or remote controller where flammable gases may leak, where there are carbon fibre or ignitable dust
suspended in the air, or where volatile flammables such as thinner or gasoline are handled.
•
Do not install the indoor unit or remote controller where the area is filled with steam or the ground is always wet. Insulation of the electric
components may be damaged in such conditions and may result in electric shock.
•
Be sure to only use refrigerant piping approved for use with R410A refrigerant. The use of unapproved piping may result in explosive
rupture.
CAUTION
•
Do not install the air conditioner for purpose other than for human comfort. Do not use the air conditioner for special applications such as
the storage of foods, animals and plants, precision machines and art objects. Deterioration of quality may result.
•
This model is not designed for free blow operation. Supply and Return air duct work must be installed. External duct work and air boxes
must be adequately insulated to prevent condensation.
•
It is recommended that a safety drain tray is installed. Ensure that it drains separately.
•
While following the instructions in this installation manual, install drain piping in order to ensure proper drainage and insulation piping in
order to prevent condensation. Improper drain piping may result in water leakage and property damage.
•
Install the indoor and outdoor units, power cords and connecting wires at least 1 metre away from televisions or radios in order to
prevent image interference or noise.
(Depending on the radio waves, a distance of 1 metre may not be sufficient enough to eliminate noise).
•
Do not install the air conditioner in the following locations:
(a) Where a mineral oil mist, oil spray vapour is produced, for example in a kitchen.
Plastic parts may deteriorate.
(b) Where corrosive gas, such as sulfuric acid gas, is produced.
Corroding copper pipes or soldered parts may result in refrigerant leakage.
(c) Near machinery emitting electromagnetic waves.
Electromagnetic waves may disturb the operation of the control system and result in a malfunction of the equipment.
(d) Where salinity in the air is relatively high.
•
Be sure to attach a return air filter (field supplied) inside the return air passage. Failure to install the filter will cause equipment failure.
