Safety Precautions
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 sta-
tion, 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.
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.
n 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.
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 opera-
tion.
• 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 oper-
ational season.
Be very careful about product transportation.
• Only one person should not carry the product if it weighs more than 20 kg.
• 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 outside unit, suspending it at the specified positions on the unit base. Also support the outside unit at four points so that it cannot slip
sideways.
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 stop-
ping 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 connect-
ing 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.
