Installation and Maintenance
WARNING
·
Installation should be performed by a professional. (Improper installation may cause water leakage,
electrical shock or fire).
·

·
·
·
·
Install the unit according to the instruction given in this manual. (Incomplete installation may cause water
leakage, electrical shock or fire).
Be sure to use the supplied or specified installation parts. (Use of other parts may cause the unit to come to
lose, water leakage, electrical shock or fire).
Install the air conditioner on a solid base that can support the unit weight. (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 local national
electrical wiring rules or code of practice.
(Insufficient capacity or incomplete electrical work may cause electrical shock or fire).
Be sure to use a dedicated power circuit. (Never use a power supply shared by another appliance).
For wiring, use a cable long enough to cover the entire distance 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 fire).
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 stress).
Incomplete connections or clamping may cause terminal overheating or fire.
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 fire).
·
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).
·
·
·
·
·
·
·
If any refrigerant has leaked out during the installation work, ventilate the room. (The refrigerant produces a
toxic gas if exposed to flames).
After all installation is completed, check to make sure that no refrigerant is leaking out. (The refrigerant
produces a toxic gas if exposed to flames).
When carrying out piping connection, take care not to let air substances other than the specified refrigerant
go into refrigeration cycle. (Otherwise, it will cause lower capacity, abnormal high pressure in the
refrigeration cycle, explosion and injury).
·
Make sure the installation has a proper earth connection. Do not earth the unit to a utility pipe, arrester, or
telephone earth. Incomplete earth may cause electrical shock. (A high surge current from lightning or other
sources may cause damage to the air conditioner).
An earth leakage circuit breaker may be required depending on site condition to prevent electrical shock.
(Failure to do so may cause electrical shock).
Disconnect the power supply before completion of wiring, piping, or checking the unit.
When moving the indoor unit and outdoor unit , please be careful,do not make the outdoor unit incline over
45 degree.

Installing the remote controller: Be sure that the length of the wire between the indoor unit and remote
controller is within 40 meters.
Pay attention to the
to avoid any injury.
·
·
·
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 fire).
Establish drain piping according to the instructions of this manual. (Inadequate piping may cause flooding).
Tighten the flare nut according to the specified method such as with a torque wrench. (If the flare nut is
tightened too hard, the flare nut may crack after a long time and cause refrigerant leakage).
