INSTALLATION LOCATION

• 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.

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.

• 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.

• 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.

NOTE

• 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 

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.
• 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.

• This device complies with part 15 of the FCC Rules.

Operation is subject to the following two conditions:
(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 occur in a particular installation. If this 
equipment does cause harmful interference to radio or television 
reception, which can be determined by turning the equipment off  
and on, the user is encouraged to try to correct the interference 
by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from 

that to which the receiver is connected.

• Consult the dealer or an experienced radio/TV technician for 

help.

• FCC Caution: To assure continued compliance, follow the 

attached installation instructions.  Any changes or modifications 
not expressly approved by the party responsible for compliance 
could void the user's authority to operate this equipment.
