1.  IMPORTANT SAFETY INFORMATION

1.1    Types of precautions

1.2  General precautions

To gain full advantage of the unit’s functions and to avoid 

malfunctions due to mishandling, we recommend that you read this 

instruction manual carefully before use.

The precautions described herein are classified as WARNING 

and CAUTION. They both contain important information regarding 

safety. Ensure that you follow them carefully.

Failure to follow these instructions may result in 

injury, even loss of life.

Do not use this unit in locations where flammable gas may 

exist. If flammable gas comes into contact with the unit, a 

fire may occur, which could result in serious injury.

If this unit exhibits any abnormal behavior (such as emitting 

smoke) there is a danger of serious injury. Disconnect the 

power supply and contact your supplier or service engineer 

immediately.

The refrigerant in this unit is safe and should not leak if the 

system is designed and installed properly. However, if a 

large amount of refrigerant leaks into a room, the oxygen 

concentration will decrease rapidly, which can cause serious 

injury. The refrigerant used in this unit is heavier than air, 

so the danger is greater in basements or other underground 

spaces.  In  the  event  of  a  refrigerant  leak,  turn  off  any 

devices that produce a naked flame and any heating devices, 

ventilate the room, and contact your supplier or service 

engineer immediately.

Toxic fumes may be produced if the refrigerant in this unit 

comes into contact with naked flames (such as from a 

heater, gas stove/burners, or electric appliances).

If this unit is used in the same room as a cooker, stove, 

hob, or burner, ventilation for sufficient fresh air must be 

ensured, otherwise the oxygen concentration will fall, which 

may cause injury.

Dispose of this unit’s packaging carefully, so children 

cannot play with it. Packaging, especially plastic packaging, 

can  be  dangerous,  can  cause  serious  injury.  Screws, 

staples and other metal packaging components can be 

sharp and should be disposed of carefully to avoid injury.

Do not attempt to inspect or repair this unit yourself. 

This unit should only be serviced and maintained by a 

professional air conditioning service engineer. Incorrect 

servicing or maintenance can cause electric shocks, fire or 

water leaks.

This unit should only be re-positioned or re-installed by 

a professional technician. Incorrect installation can lead 

to electric shocks, fire or water leaks. The installation 

and grounding of electrical appliances should only be 

carried out by licensed professionals. Ask your supplier or 

installation engineer for further information.

Do not allow this unit or its remote controller to come into 

contact with water, as this can lead to electric shocks or 

fire.

Do not use paint, varnish, hair spray, other flammable 

sprays or other liquids that may give off flammable fumes/

vapor near this unit, as doing so can cause fires.

When replacing a fuse, ensure that the new fuse to be 

installed completely complies with requirements.

Do not open or remove the unit's panel when the unit is 

powered  on.  Touching  the  unit's  internal  components 

while the unit is powered on can lead to electric shocks or 

injuries caused by moving parts such as the unit's fan.

Ensure that the power supply is disconnected before any 

servicing or maintenance is carried out.

Do not touch the unit or its remote controller with wet 

hands, as doing so can lead to electric shocks.

Do not allow children to play near this unit, as doing so 

risks injury.

Do not insert your fingers or other objects into the unit’s 

air  inlet  or  air  outlet  to  avoid  injury  or  damage  to  the 

equipment.

Do not spray any liquids onto the unit or allow any liquids 

to drip onto the unit. 

Do not place vases or other liquid containers on the unit 

or in places where liquid could drip onto it. Water or other 

liquids that come into contact with the unit can lead to 

electric shocks or fires.

Do  not  remove  the  remote  controller’s  front  or  back 

overs and do not touch the remote controller’s internal 

components, as doing so can cause injury. If the remote 

controller stops working, contact your supplier or service 

engineer.

Failure to observe these instructions may result in 

serious property damage or injury.
