¡
Do not put the drain pipe directly into the ditch where toxic gas such as sulfur is generated.
Toxic gas would flow into the room. Also, this may cause corrosion of indoor unit, and malfunction or refrigerant leakage.
¡
Be sure to bring back the packing material, form polystyrene, band and vinyl back etc., of the indoor and/or outdoor units after
complete the installation work, and then implement appropriate measures such as breaking them.
¡
When setting up or moving the location of the air conditioner, do not mix air etc. or anything other than the designated refrigerant
(R410A) within the refrigeration cycle.
Rupture and injury caused by abnormal high pressure can result from such mixing.
¡
Do not processing, splice the power cord, or share a socket with other power plugs.
This may cause fire or electric shock due to defecting contact, defecting insulation and over-current etc.
¡
Do not bundling, winding or processing for the power cord. Or, do not deforming the power plug due to tread it.
This may cause fire or heating.
¡
Execute proper grounding. Do not connect the ground wire to a gas pipe, water pipe, lightning rod or a telephone ground wire.
Improper placement of ground wires can result in electric shock.
¡
Please avoid installing this unit in the locations where oil splashes and moisture are abundant (e.g., kitchens, mechanical workshops) or
where the outside air is likely to flow in. These locations may cause corrosion and lower performance of the heat exchanger and cause
damage to plastic parts.
¡
Please avoid installing this unit in the locations with corrosive gases (such as sulfurous acid gas), inflammable gases (such as thinner,
gasoline) and areas where there are possibilities of gas accumulation or where a volatile inflammable material is handled. These
locations can cause corrosion to the heat exchanger and damage to plastic parts. Also, the inflammable gas could cause fire.
¡
Please avoid installing this unit in the vicinity of equipment generating electromagnetic waves such as hospital equipment or equipment
generating high-frequency waves. A failure to observe this instruction may result in controller performance errors due to noise generation.
¡
Please avoid installing and using this unit in a place where it is subject to sea breezes (coastal area). Installation in such a place may
result in the corrosion of exterior panels and the heat exchanger.
¡
Do not place the remote control at locations that receives direct sunlight. This may cause malfunction and deformation.
¡
Spatters from welding, etc., if hit the unit, can damage (pinhole) its drain pan and other components and cause a water leak. Care must
be taken in performing a welding operation near this unit and take necessary precautions to prevent spatters from entering this unit.
¡
For installation work, be careful not to get injured with the heat exchanger, piping flare portion or screws etc.
¡
For the drain pipe, follow the installation manual to insure that it allows proper drainage and thermally insulate it to prevent condensation.
Inadequate plumbing can result in water leakage and water damage to interior items.
¡
The installation of an earth leakage breaker is necessary depending on the established location of the unit. Not installing an earth
leakage breaker may result in electric shock.
¡
When perform the air conditioner operation (cooling or drying operation) in which ventilator is installed in the room. In this case, using
the air conditioner in parallel with the ventilator, there is the possibility that drain water may backflow in accordance with the room
lapse into the negative pressure status. Therefore, set up the opening port such as incorporate the air into the room that may appropriate
to ventilation (For example; Open the door a little). In addition, just as above, so set up the opening port if the room lapse into negative
pressure status due to register of the wind for the high rise apartment etc.
¡
Secure the regulated space for inspection and maintenance.
When it is not possible to keep enough space, this may cause injury due to falling from the installation place.
¡
To prevent the falling, institute the everlasting ladder and handrail etc., to the aisle when installing the outdoor unit in the location with
rooftop or altitude.
Or, for surrounding of the outdoor unit, institute the fence and handrail etc., to the aisle to prevent the falling.
¡
Performing the heat insulation and condensation of the refrigerant piping.
If the heat insulation and condensation of the refrigerant piping is not correctly, this may cause the water leakage, dew dropping and
household wetting etc.
¡
Be careful not to injury due to damage of the unit installing work when leaving of the packaging materials.
¡
Do not install the unit where there is a concern about leakage of combustible gas.
The rare event of leaked gas collecting around the unit could result in an outbreak of fire.
¡
Do not touch the suction or aluminum fin on the outdoor unit.
This may cause injury.
¡
Do not install the outdoor unit where is likely to be a nest for small animals.
Small animals may come into the electronic components and may cause breakdown and fire. Also,instruct the user to keep the surroundings
clean.
¡
Do not install the outdoor unit at the place where fan airflow falls on the garden tree etc.
This may cause damage to the garden tree etc., due to the fan airflow.
¡
Do not put anything on the outdoor unit and operating the unit.
This may cause damage the objects or injury due to falling to the object.
