• 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 preserving foods, works of art,
etc. It is a consumer air conditioner, 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 installting 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 creating noise that disturbs medical treatment or
image broadcasting.
• Do not install the product where it is exposed to sea wind (salt spray) directly.
- It may cause corrosion on the product. Corrosion, particularly on the condenser and
evaporator fins, could cause product malfunction or inefficient operation.
Operation
• Do not use the air conditioner in special environments.
- Oil, steam, sulfuric smoke, etc. can significantly reduce the performance of the air
conditioner or damage its parts.
• Do not block the inlet or outlet.
- It may cause failure of appliance or accident.
• Make the connections securely so that the outside force of the cable may not be
applied to the terminals.
- Inadequate connection and fastening may generate heat and cause a fire.
• Be sure the installation area does not deteriorate with age.
- If the base collapses, the air conditioner could fall with it, causing property damage,
product failure, or personal injury.
• Install and insulate the drain hose to ensure that water is drained away properly based on
the installation manual.
- A bad connection may cause water leakage.
• Be very careful about product transportation.
- Only one person should not carry the product if it weighs more than 20 kg (44 lbs).
- Some products use PP bands for packaging. Do not use any PP bands for a means
of transportation. It is dangerous.
- Do not touch the heat exchanger fins. Doing so may cut your fingers.
- When transporting the outdoor unit, suspending it at the specified positions on the
unit base. Also support the outdoor unit at four points so that it cannot slip
sideways.
• Safely dispose of the packing materials.
- Packing materials, such as nails and other metal or wooden parts, may cause stabs or
other injuries.
- Tear apart and throw away plastic packaging bags so that children may not play with
them. If children play with a plastic bag which was not torn apart, they face the risk of
suffocation.
• Turn on the power at least 6 hours before starting operation.
- Starting operation immediately after turning on the main power switch can result in
severe damage to internal parts. Keep the power switch turned on during the
operational season.
• Do not touch any of the refrigerant piping during and after operation.
- It can cause a burn or frostbite.
• Do not operate the air conditioner with the panels or guards removed.
- Rotating, hot, or high-voltage parts can cause injuries.
• Do not directly turn off the main power switch after stopping operation.
- Wait at least 5 minutes before turning off the main power switch. Otherwise it may
result in water leakage or other problems.
• Auto-addressing should be done in condition of connecting the power of all indoor and
outdoour units. Auto-addressing should also be done in case of changing the indoor unit
PCB.
• Use a firm stool or ladder when cleaning or maintaining the air conditioner.
- Be careful and avoid personal injury.
• Do not insert hands or other objects through the air inlet or outlet while the air
conditioner is plugged in.
- There are sharp and moving parts that could cause personal injury.
• If the supply cord is damaged, it must be replaced by the manufacturer, its service
agent or similarly qualified persons in order to avoid a harzard.
• This equipment shall be provided with a supply conductor complying with the national
regulation.
• This appliance is not intended for use by persons (including children) with reduced
physical, sensory or mental capabilities or lack of experience and knowledge, unless
they have been given supervision or instruction concerning use of the appliance by a
person responsible for their safety. Children should be supervised to ensure that they
do not play with the appliance.
• Means for disconnection must be incorporated in the fixed wiring in accordance with
the wiring rules.
