or an Authorized Service Center.
- There is risk of fire, electric shock, explosion, or injury.
• Do not install, remove, or re-install the unit by yourself (customer).
- There is risk of fire, electric shock, explosion, or injury.
• Prepare for strong wind or earthquake and install the unit at the
specified place.
- Improper installation may cause the unit to topple and result in
injury.
• When installing and moving the Product to another site, do not
charge it with a different refrigerant from the refrigerant specified
on the unit.
- If a different refrigerant or air is mixed with the original
refrigerant, the refrigerant cycle may malfunction and the unit
may be damaged.
• Securely install the cover of control box and the panel.
- If the cover and panel are not installed securely, dust or water
may enter the outdoor unit and fire or electric shock may result.
• If the Product is installed in a small room, measures must be
taken to prevent the refrigerant concentration from exceeding the
safety limit when the refrigerant leaks.
- Consult the dealer regarding the appropriate measures to prevent
the safety limit from being exceeded. Should the refrigerant leak
and cause the safety limit to be exceeded, hazards due to lack of
oxygen in the room could result.
• Use the correctly rated breaker or fuse.

• Have all electric work done by a licensed electrician according to
regulations and the instructions given in this manual and always
use a special circuit.
- If the power source capacity is inadequate or electric work is
performed improperly, electric shock or fire may result.
• There must be no obstruction above the unit.

circulated back to the inlet of the condenser coil. The condenser
fans are propeller type and will not operate with ductwork on the
fan outlet.
