1 Safety Precautions
WARNING! This mark indicates procedures which, if improperly performed, might lead to
the death or serious injury of the user.
CAUTION! This mark indicates procedures which, if improperly performed, might possibly
result in personal harm to the user, or damage to property.
WARNING !
Installation should be left to the dealer or another professional. Improper installation may cause water
leakage, electrical shock, or re.
Install the air conditioner according to the instructions given in this manual. Incomplete installation may
cause water leakage, electrical shock, or re.
Be sure to use the supplied or specied installation parts. Use of other parts may cause the unit to
come to lose, water leakage, electrical shock, or re.
Install the air conditioner on a solid base that can support the weight of the unit. An inadequate base or
incomplete installation may cause injury in the event the unit falls off the base.
Electrical work should be carried out in accordance with the installation manual and the national
electrical wiring rules or code of practice. Insufcient capacity or incomplete electrical work may cause
electrical shock or re.
Be sure to use a dedicated power circuit. Never use a power supply shared by another appliance.
For wiring, use a cable length enough to cover the entire distance with no connection. Do not use an
extension cord. Do not put other loads on the power supply, use a dedicated power circuit. (Failure to
do so may cause abnormal heat, electric shock or re.)
Use the specified types of wires for electrical connections between the indoor and outdoor units.
Firmly clamp the interconnecting wires so their terminals receive no external stresses. Incomplete
connections or clamping may cause terminal overheating or re.
After connecting interconnecting and supply wiring be sure to shape the cables so that they do not
put undue force on the electrical covers or panels. Install covers over the wires. Incomplete cover
installation may cause terminal overheating, electrical shock, or re.
If any refrigerant has leaked out during the installation work, ventilate the room. (The refrigerant
produces a toxic gas if exposed to ames.)
After all installation is complete, check to make sure that no refrigerant is leaking out. (The refrigerant
produces a toxic gas if exposed to ames.)

2
When installing or relocating the system, be sure to keep the refrigerant circuit free from substances
other than the specified refrigerant (R410A), such as air. (Any presence of air or other foreign
substance in the refrigerant circuit causes an abnormal pressure rise or rupture, resulting in injury.)
During pump-down, stop the compressor before removing the refrigerant piping. If the compressor is
still running and the stop valve is open during pump-down, air will be sucked in when the refrigerant
piping is removed, causing abnormal pressure in the freezer cycle which will lead to breakage and
even injury.
During installation, attach the refrigerant piping securely before running the compressor. If the
compressor is not attached and the stop valve is open during pump-down, air will be sucked in when
the compressor is run, causing abnormal pressure in the freezer cycle which will lead to breakage and
even injury.
Be sure to establish an earth. Do not earth the unit to a utility pipe, arrester, or telephone earth.
Incomplete earth may cause electrical shock, or fire. A high surge current from lightning or other
sources may cause damage to the air conditioner.
Be sure to install an earth leakage breaker. Failure to install an earth leakage breaker may result in
electric shocks, or re.
CAUTION !
Do not install the air conditioner in a place where there is danger of exposure to inflammable gas
leakage. If the gas leaks and builds up around the unit, it may catch re.
Establish drain piping according to the instructions of this manual. Inadequate piping may cause
ooding.
Tighten the are nut according to the specied method such as with a torque wrench. If the are nut is
tightened too hard, the are nut may crack after a long time and cause refrigerant leakage.
