There are two types of precautions as described below:
Warning: Failure to comply may lead to death or serious injury.
Caution: Failure to comply may lead to injury or damage of the
unit. Depending on the situation, this may also lead to serious injury.
Once the installation is completed, and the unit has been tested and
verified to be operating normally, please explain to the customer how
to use and maintain the unit according to this manual. In addition,
make sure that the manual is kept properly for future reference.

Safety Precautions
Read carefully before you install the air conditioner to make sure that
the installation is correct.
Warning
$ Installation, maintenance and cleaning the filter work must be
carried out by professional installers. Refrain from doing it yourself.
Improper installation may cause water leakage, electric shock, or
fire.

required. A high concentration of refrigerant in an airtight space can
cause oxygen insufficiency (anoxia).

1) Where there is oil or gas, such as the kitchen. Otherwise, the
plastic parts may age, fall off or water may leak.
2) where there are corrosive gases (such as sulphur dioxide).
Corrosion in the copper pipes or welded parts may cause the
refrigerant to leak.
3) Where there are machines emitting electromagnetic waves.
Electromagnetic waves may interfere with the control system,
causing the unit to malfunction.
4) Where there is a high salt content in the air. When exposed to
air with a high salt content, the mechanical parts will experience
accelerated ageing which will severely compromise the service
life of the unit.
5) Where there are major voltage fluctuations. Operating the unit
using a power supply system that has large voltage fluctuations
will reduce the service life of the electronic components, and
cause the unit's controller system to malfunction.
6) Where there is a risk of leakage of flammable gases. Examples
are sites that contain carbon fibres or combustible dust in the
air, or where there are volatile combustibles (such as diluent or
petrol). The above gases may cause explosion and fire.
7) Do not touch the fins of the heat exchanger as this may lead to
injury.
8) Some products use the PP packing belt. Do not pull or tug on
the PP packing belt when you transport the product. It will be
dangerous if the packing belt breaks.
9) Note the recycling requirements for nails, wood, carton and
other packaging materials. Do not discard these materials
directly as these may lead to bodily harm.
10) Tear up the packaging bag for recycling to prevent children from
playing with it, and leading to suffocation.
