Installation and Maintenance

WARNING

Installation should be left to the dealer or another professional person. (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 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 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 stresses.)

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 ,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 reduces 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. )

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. (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
