1.6 APPLICATION DATA
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 20A) 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 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 insufficient, 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.
Insufficient power source circuit capacity and defective installment execution can be the cause of electric shocks and fires.
•This equipment must be installed with earth leakage circuit breaker (ELCB). Otherwise, it may cause electrical shock and fire 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 fire.
•Take care that wiring does not rise upward, and accurately install the lid/service panel.It’s improper installation can also result heat genera-
tion 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 (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, 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.
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 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.
•Install the outdoor unit so that the aluminum fins 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 flame.
Cautions for installation
①The system should be applied to places as households, residences and the like.
②The equipment shall be installed in accordance with national wiring regulations.
③The connection to the fixed 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.
④When the outdoor unit has a possibility of being overturned or being displaced and fall from its original installation position, the
outdoor unit should be fixed in its position by use of anchor bolts or wires.

Drain hose
[Procedure for exchanging the drain hose.]
1. Remove the drain hose. 2. Remove the drain cap. 3. Insert the drain cap. 4. Connect the drain hose.
①Mounting of connecting wires
ⓐRemove the lid.
ⓑRemove the wiring clamp.
ⓒConnect the connecting wire securely to the terminal block.
Use cable for interconnection wiring to avoid loosening of the
wires.
CENELEC code for cables Required field cables.
H05RNR3G1.5 (Example) or 245IEC57
H Harmonized cable type
05 300/500 volts
R Natural-and/or synth. rubber wire insulation
N Polychloroprene rubber conductors insulation
R Standed core
4or5 Number of conductors
G One conductor of the cables is the earth conductor (yel-
low/green)
1.5 Section of copper wire (mm2)
•Connect the connection wire securely to the terminal block.
If the wire is not affixed completely, contact will be poor,
and it is dangerous as the terminal block may heat up and
catch fire.
•Take care not to confuse the terminal numbers for indoor
and outdoor connections.
•Earth lead wire shall be longer than the other lead wires for
the electrical safety in case of the slipping out of the cord
from the anchorage.
•The earth line of power cord must be properly earthed.
•Affix the connection wire using the wiring clamp.
ⓓFix the connecting wire by wiring clamp.
ⓔAttach the lid.
ⓕClose the air inlet panel.
