Installation Manual
Safety Precautions
Read carefully before you install the air conditioner to make sure that
the installation is correct.
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.
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.
‡ Install the air conditioner according to the steps described in this
manual. Improper installation may cause water leakage, electric
shock, or fire.
‡ For installation in smaller rooms, you must adopt the relevant
measures to prevent the refrigerant concentration from exceeding
the limit. Please consult the sales agent on the relevant measures
required. A high concentration of refrigerant in an airtight space can
cause oxygen insufficiency (anoxia).
‡ Make sure the required parts and accessories are installed. Using
unspecified parts may cause the air conditioner to malfunction or
drop, as well as water leakage, electric shock, and fire.
‡ Mount the air conditioner in a place that is sturdy enough to bear its
weight. If the base is not secured properly, the air conditioner may
drop leading to damages and injuries.
‡ Take in full consideration to the effects of strong winds, typhoons
and earthquakes, and reinforce the installation. Improper installa-
tion may cause the air conditioner to drop leading to accidents.
‡ Make sure a standalone circuit is used for the power supply. All
electrical parts must comply with the local laws and regulations, and
what is stated in this installation manual. The installation works must
be carried out by a professional and qualified electrician. Insufficient
capacity or improper electrical works can lead to electric shock or fire.
‡ Use only electrical cables that fulfil the specifications. All wiring on
site must be carried out in accordance with the connection diagram
attached to the product. Make sure that there are no external forces
acting on the terminals and wires. Improper wiring and installation
may cause a fire.
‡ Make sure the power cord, communication and controller wiring are
straight and level when you are working on the connections, and the
cover on the electric box is tight. If the electric box is not closed
properly, it may lead to electric shock, fire or overheating of
electrical components.
‡ If the refrigerant leaks during installation, open the doors and
windows immediately to ventilate the area. Refrigerant can produce
toxic gases when in contact with fire.
‡ Switch off the power supply before touching any electrical
component.
‡ To prevent electrical shock, do not touch a switch with wet hands.
‡ Do not come in direct contact with the refrigerant leaking from the
connections of refrigerant piping. Otherwise, it may lead to frostbite.
‡ The air conditioner must be grounded. Do not connect the earth line
(ground) to gas piping, water piping, lightning rods or telephone
earth lines. Improper grounding can lead to electric shock or fire,
and may cause mechanical failure due to current surges from
lightning and so on.
‡ The earth leakage circuit breaker must be installed. There is a risk
of electric shock or fire if the earth leakage circuit breaker is not
installed.
Caution
‡
Install the water discharge piping according to the steps
described in this manual, and make sure that the water
discharge is smooth, and the piping is properly insulated to
prevent condensation. Improper installation of the water
discharge piping may lead to water leakage, and damage the
indoor furniture.
‡
When mounting the indoor and outdoor units, make sure the
power cord is installed at a distance of at least 1 m away from
any TV or radio so as to prevent noise or interference with the
images.
‡
The refrigerant required for the installation is R410A. Make sure
the refrigerant is correct before installation. Incorrect refrigerant
may cause the unit to malfunction.
‡
Do not install the air conditioner in the following places:
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
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.
