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.
