CAUTION
Installation
• Always check for gas (refrigerant) leakage after installation 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 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.
• 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 condi-
tioner to operate erroneously, or fail to operate. On the other hand, the air
conditioner may affect such equipment by creating noise that disturbs med-
ical treatment or image broadcasting.
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.
-
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 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 re-
sult in severe damage to internal parts. Keep the power switch turned on dur-
ing 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.
