NOTE
CAUTION
NOTICE
• We recommend that this air conditioner be installed
properly by qualified installation technicians in
accordance with the Installation Instructions
provided with the unit.
• Before installation, check that the voltage of the electric
supply in your home or office is the same as the voltage
shown on the nameplate.
• Do not install this air conditioner
where there are fumes or flammable
gases, or in an extremely humid space
such as a greenhouse.
• Do not install the air conditioner where
excessively high heat-generating
objects are placed.
Avoid:
To protect the air conditioner from heavy corrosion, avoid installing
the outdoor unit where salty sea water can splash directly onto it or
in sulphurous air near a spa.
ELECTRICAL REQUIREMENTS
1. All wiring must conform to the local electrical codes.
Consult your dealer or a qualified electrician for details.
2. Each unit must be properly grounded with a ground (or
earth) wire or through the supply wiring.
3. Wiring must be done by a qualified electrician.
Pull off the power plug from a receptacle, or switch off the breaker, or
switch off the power disconnecting mean to isolate the air conditioner
from the main power supply when not in use for a long time.
• To prevent possible hazards from insulation failure,
the unit must be grounded.
• Do not clean inside the indoor and outdoor units by users.
Engage authorized dealer or specialist for cleaning.
• In case of malfunction of this appliance, do not repair by
yourself. Contact to the sales dealer or service dealer for a
repair.
• Refrigerant gas leakage may cause fire.
• For safety, be sure to turn the air conditioner off and
also to disconnect the power before cleaning.
• Pull off the power plug from a receptacle, or switch off the
