Safety Precautions
ENGLISH
Installation Manual 5
• 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 equip-
ment 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.
• 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.
• 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 plas-
tic 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.
