INSTALLATION LOCATION
NOTE
• 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 heatgenerating 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.
SAFETY INSTRUCTIONS
• Read this Instruction Manual carefully before using this air conditioner. If
you still have any difficulties or problems, consult your dealer for help.
• This air conditioner is designed to give you comfortable room conditions.
Use this only for its intended purpose as described in this Instruction
Manual.
• Confirm to authorized dealer or specialist on usage of specified
refrigerant type.
Using of refrigerant other than the specified type may cause product
damage, burst and injury etc.
• Never touch the unit with wet hands.
• Never use or store gasoline or other flammable vapor or liquid near the
air conditioner — it is very dangerous.
• Do not use this appliance in a potentially explosive atmosphere.
• This air conditioner has no ventilator for intaking fresh air from
outdoors. You must open doors or windows frequently when you use
gas or oil heating appliances in the same room, which consume a lot of
oxygen from the air. Otherwise there is a risk of suffocation in an
extreme case.
• Do not swallow the battery.
• After removing the battery from remote controller, keep it away from the
reach of children. The battery can cause death by suffocation if
swallowed.
• When inserting the battery, make sure the polarities (+ and -) are correct.
3
• To prevent possible hazards from insulation failure, the unit must
CAUTION
NOTICE
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 breaker, or
switch off the power disconnecting mean to isolate the air conditioner
from the main power supply in case of emergency.
• Do not turn the air conditioner on and off from the power mains switch.
Use the ON/OFF operation button.
• Do not stick anything into the air outlet of the outdoor unit.
This is dangerous because the fan is rotating at high speed.
• Do not touch the air inlet or the sharp aluminum
fins of the outdoor unit. You may get injured.
• Keep the fire alarm and the air outlet at least 1.5m away from the unit.
• Do not let children play with the air conditioner.

(1) This device may not cause harmful interference, and (2) this device must
accept any interference received, including interference that may cause
undesired operation.
• This equipment has been tested and found to comply with the limits for
a Class B digital device, pursuant to part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses and
can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not
