Safety precautions

•

Please read these “Safety Precautions” 

fi

rst 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 con

fi

rming 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 15A) with a contact separation of at least 3mm.

•

The appliance shall be installed in accordance with national wiring regulations.

•

This system should be applied to places as households, residences and the like. Application to inferior environment 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 

fi

res.

•

Execute the installation accurately, based on following the installation manual. Again, improper installations can result in water leakage, electric
shocks and 

fi

res.

•

For installation, con

fi

rm that the installation site can suf

fi

ciently support heavy weight. When strength is insuf

fi

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 exclusive use circuits are used.
Insuf

fi

cient power source circuit capacity and defective installment execution can be the cause of electric shocks and 

fi

res.

•

This equipment must be installed with earth leakage circuit breaker (ELCB). Otherwise, it may cause electrical shock and

fi

re in case of equipment

breakdown.

•

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 

fi

re.

•

Take care that wiring does not rise upward, and accurately install the lid/service panel. It’s improper installation can also result heat generation or

fi

re.

•

When setting up or moving the location of the air conditioner, do not mix air etc. or anything other than the designated refrigerant (R22) 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, 

fi

re and refrigerant leakage.

•

Ventilate the work area when refrigerant leaks during the operation.
Coming in contact with 

fi

re, refrigerant could generate toxic gas.

•

Con

fi

rm after the foundation construction work that refrigerant does not leak.

If coming in contact with 

fi

re of a fan heater, a stove or movable cooking stove, etc., refrigerant leaking in the room could generate toxic gas.

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.
No 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 even of leaked gas collecting around the unit could result in an outbreak of 

fi

re.

•

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.

•

Install the outdoor unit so that the aluminum 

fi

ns on the air heat exchanger cannot be touched. Failure to observe this may result in injury.

•

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 

fl

ame.

Cautions for installation

①

The system should be applied to places as households, residences and the like.

②

The equipment shall be installed in accordance with national wiring regulations.

③

The connection to the

fi

xed wiring of the mains supply must be made via a double pole isolating switch with a contact gap of at least

3mm in each pole.

④

When the outdoor unit has a possibility of being overturned or being displaced and fall from its original installation position, the outdoor

unit should be 

fi

xed in its position by use of anchor bolts or wires.
