INSTALLATION LOCATION

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.
ELECTRICAL REQUIREMENTS
SAFETY INSTRUCTIONS
• Read these Operating Instructions 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 these Operating Instructions. • 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.
 All wiring must conform to the local electrical codes. Consult your dealer or a qualified 
electrician for details.
 It is strongly recommended to be installed with Earth Leakage Circuit Breaker (ELCB) or 
Residual Current Device (RCD) to prevent electric shock or fire.
 Each unit must be properly grounded with a ground (or earth) wire or through the supply 
wiring.
 Wiring must be done by a qualified electrician.
To warm up the system, the power mains must be turned on at least five (5) hours 
before operation. Leave the power mains ON unless you will not be using this 
appliance for an extended period.
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.
• 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.
• 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.
• Check for a leaking refrigerant! Refrigerant gas may produce a toxic gas if it comes 
in contact with fire.

OPERATION CONDITION
• For safety, be sure to turn the air conditioner off and also to disconnect the 
power before cleaning or servicing.
• 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 
5 feet (1.5 m) away from the unit.
• Do not let children play with the air conditioner.
• Do not cool or heat the room too much if babies or invalids are present.
• Do not sit or step on the unit. 
You may fall down accidentally.
• Do not stick any object 
into the FAN CASE. 
You may be injured and 
the unit may be damaged.
• The compressor may occasionally stop during thunderstorms.
This is not a mechanical failure. The unit automatically recovers after a few 
minutes.
