SAFETY PRECAUTIONS
¡
Please read these “Safety Precautions” first then accurately execute the installation work.
¡
Though the precautionary points indicated herein are divided under two headings,
WARNING
and
CAUTION
, those points which are
related to the strong possibility of an installation done in error resulting in death or serious injury are listed in the
WARNING
section. However, there is also a possibility of serious consequences in relationship to the points listed in the
CAUTION
section as well. In either case, important safety related information is indicated, so by all means, properly observe all that is mentioned.
¡
After completing the installation, along with confirming that no abnormalities were seen from the operation tests, please explain
operating methods as well as maintenance methods to the user (customer) of this equipment, based on the owner’s manual.
Moreover, ask the customer to keep this sheet together with the owner’s manual.
WARNING
¡
To disconnect the appliance from the mains supply this appliance must be connected to the mains by means of
a circuit breaker or a switch (use a recognized 16A) with a contact separation of at least 3mm.
¡
The appliance shall be installed in accordance with national wiring regulations.
¡
When a plug is connected to the power cord, a plug conforming to the IEC60884-1 standard must be used.
¡
This system should be applied to places as households, residences and the like. Application to inferior environ-
ment such as engineering shop could cause equipment malfunction.
¡
Please entrust installation to either the company which sold you the equipment or to a professional contractor.
Defects from improper installations can be the cause of water leakage, electric shocks and fires.
¡
Execute the installation accurately, based on following the installation manual. Again, improper installations can
result in water leakage, electric shocks and fires.
¡
For installation, confirm that the installation site can sufficiently support heavy weight. When strength is insuffi-
cient, injury can result from a falling of the unit.
¡
For electrical work, please see that a licensed electrician executes the work while following the safety standards
related to electrical equipment, and local regulations as well as the installation instructions, and that only exclu-
sive use circuits are used.
Insufficient power source circuit capacity and defective installment execution can be the cause of electric shocks
and fires.
¡
Accurately connect wiring using the proper cable, and insure that the external force of the cable is not conducted
to the terminal connection part, through properly securing it. Improper connection or securing can result in heat
generation or fire.
¡
Take care that wiring does not rise upward, and accurately install the lid/service panel.It’s improper installation
can also result in heat generation or fire.
¡
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.
¡
Always use accessory parts and authorized parts for installation construction. Using parts not authorized by this
company can result in water leakage, electric shock, fire and refrigerant leakage.
¡
Ventilate the work area when refrigerant leaks during the operation.
Coming in contact with fire, refrigerant could generate toxic gas.
¡
Confirm after the foundation construction work that refrigerant does not leak.
If coming in contact with fire of a fan heater, a stove or movable cooking stove, etc., refrigerant leaking in the
room could generate toxic gas.
¡
In joining pipes, do not use conventional (R22) pipng flare nuts, etc. The use of conventional pipng materials may
lead to the rapture of piping due to higher pressure used for the refrigerant cycle and possible personal injury.
(Use only piping material designed specifically for R410A)
CAUTION
¡
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.
¡
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.
¡
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.
¡
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.
¡
Do not place objects near the outdoor unit or allow leaves to gather around the unit. If there are objects or leaves
around the outdoor unit, small animals may enter unit and contact electrical parts resulting in break down,
emission of smoke or flame.
