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.
•
• 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.

Contents
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.
10. The Explain Of The Display Panel..............................................15
The appliance shall be installed in accordance with national wiring
regulations.
The appliance must be installed 2,3m above floor.
If the supply cord is damaged, it must be replaced by the
manufacturer or its service agent or a similarly qualified person in
order to avoid a hazard.
An all-pole disconnection switch having a contact separation of at
least 3mm in all poles should be connected in fixed wiring.
The temperature of refrigerant circuit will be high, please keep the
interconnection cable away from the copper tube.
The power cord type designation is H05RN-For above/H07RN-F.

Installation Manual..............................................................................1
Check the power supply before installation. Ensure that the power
supply must be reliably grounded following local, state and National
Electrical Codes. If not, for example, if the ground wire is detected
charged, installation is prohibited before it is rectified. Otherwise,
there is a risk of fire and electric shock, causing physical injury or
death.
Check the electric wire, water and gas pipeline layout inside the
wall, floor and ceiling before installation. Do not implement drilling
unless confirm safety with the user, especially for the hidden
power wire. An electroprobe can be used to test whether a wire is
passing by at the drilling location, to prevent physical injury or
death caused by insulation broken cords.
