4 Outside Unit
Safety Precautions
Ventilate before operating air conditioner when gas
leaked out.
• It may cause explosion, fire, and burn.
Securely install the cover of control box and the panel.
• If the cover and panel are not installed securely, dust or water may
enter the outside unit and fire or electric shock may result.
If the air conditioner is installed in a small room, measures
must be taken to prevent the refrigerant concentration from
exceeding the safety limit when the refrigerant leaks.
• Consult the dealer regarding the appropriate measures to prevent the
safety limit from being exceeded. Should the refrigerant leak and
cause the safety limit to be exceeded, harzards due to lack of oxygen
in the room could result.
Use a vacuum pump or Inert (nitrogen) gas when doing leakage
test or air purge. Do not compress air or Oxygen and Do not use
Flammable gases. Otherwise, it may cause fire or explosion.
• There is the risk of death, injury, fire or explosion.
n Operation
Do not damage or use an unspecified power cord.
• There is risk of fire, electric shock, explosion, or injury.
Use a dedicated outlet for this appliance.
• There is risk of fire or electrical shock.
Be cautious that water could not enter the product.
• There is risk of fire, electric shock, or product damage.
Do not touch the power switch with wet hands.
• There is risk of fire, electric shock, explosion, or injury.
When the product is soaked (flooded or
submerged), contact an Authorized Service Center.
• There is risk of fire or electric shock.
Be cautious not to touch the sharp edges when
installing.
• It may cause injury.
Take care to ensure that nobody could step on or fall
onto the outside unit.
• This could result in personal injury and product damage.
Do not open the inlet grille of the product during operation.
(Do not touch the electrostatic filter, if the unit is so equipped.)
• There is risk of physical injury, electric shock, or product failure.
n Installation
Always check for gas (refrigerant) leakage after installa-
tion or repair of product.
• Low refrigerant levels may cause failure of product.
Do not install the product where the noise or hot air from
the outside unit could damage the neighborhoods.
• It may cause a problem for your neighbors.
Keep level even when installing the product.
• To avoid vibration or water leakage.
Do not install the unit where combustible gas may leak.
• If the gas leaks and accumulates around the unit, an explosion may result.
Use power cables of sufficient current
carrying capacity and rating.
• Cables that are too small may leak, generate heat, and cause a fire.
Do not use the product for special purposes, such as pre-
serving foods, works of art, etc. It is a consumer air condi-
tioner, not a precision refrigeration system.
• There is risk of damage or loss of property.
Keep the unit away from children. The heat exchanger is
very sharp.
• It can cause the injury, such as cutting the finger. Also the damaged fin may
result in degradation of capacity.
When installing the unit in a hospital, communication station,
or similar place, provide sufficient protection against noise.
• The inverter equipment, private power generator, high-frequency medical equipment, or
radio communication equipment may cause the air conditioner to operate erroneously, or
fail to operate. On the other hand, the air conditioner may affect such equipment by cre-
ating noise that disturbs medical treatment or image broadcasting.
