Installation Manual 5
Safety Precautions
- 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 con-
ditioner 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 20kg.
- Some products use PP bands for packaging. Do not use any PP bands for a means of transportation. It is dan-
gerous.
- 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 out-
side 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 6hours 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 5minutes 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.
