Safety precautions
Installation
1
WARNING
Installation or maintenance
must be performed by qua-
lified professionals.
The appliance shall be in-
stalled in accordance with
national wiring regulations.
According tothe local safe-
ty regulations, use quali-
fied power supply circuit
and circuit breaker.
All wires of indoor unit and
outdoor unit should be con-
nected by a professional.
Be sure to cut off the power
supply before proceeding
any work related to elec-
tricity and safety.
Make sure the power supp-
ly matches with the require-
ment of air conditioner.
Unstable power supply or
incorrect wiring may result
in electric shock, fire haza-
rd or malfunction. Please
install proper power supply
cables before using the air
conditioner.
The grounding resistance
should comply with nation-
al electric safety regula-
tions.
Air Conditioner should be
properly grounded. Inco-
rrect grounding may cause
electric shock.
Do not put through the
power before finishing in-
stallation.
Do install the circuit brea-
ker. If not, it may cause
malfunction.
An all-pole disconnection
switch having a contact se-
paration of at least 3mm in
all poles should be conne-
cted in fixed wiring.
Circuit breaker should be
included magnet buckle
and heating buckle func-
tion. It can protect the
overload and circuit-short.

CAUTION
Instructions for installation
and use of this product are
provided by the manufac-
turer.
Select a location which is
out of reach for children
and far away from animals
or plants. If it is unavoid-
able, please add the fence
for safety purpose.
The indoor unit should be
installed close tothe wall.
Don't use unqualified pow-
er cord.
If the length of power con-
nection wire is insufficient,
please contact the supplier
for a new one.
The appliance must be po-
sitioned sothat the plug is
accessible.
For the air conditioner with
plug, the plug should be re-
achable after finishing in-
stallation.
For the air conditioner with-
out plug, a circuit breaker
must be installed in the
line.
The yellow-green wire in
air conditioner is ground-
ing wire, which can't be us-
ed for other purposes.
The air conditioner is the
first class electric applian-
ce. It must be properly gro-
under with specialized gr-
ounding device by a pro-
fessional. Please make
sure it is always ground-
ed effectively, otherwise it
may cause electric shock.
The temperature of refri-
gerant circuit will be high,
please keep the interconn-
ection cable away from the
copper tube.

WARNING
This appliance can be used
by children aged from 8
years and above and per-
sons with reduced physi-
cal, sensory or mental ca-
pabilities or lack of expe-
rience and knowledge if
they have been given su-
pervision or instruction con-
cerning use of the applian-
ce in a safe way and un-
derstand the hazards in-
volved.
Children shall not play with
the appliance.
Cleaning and user main-
tenance shall not be made
by children without super-
vision.
If the supply cord is damag-
ed, it must be replaced by
the manufacturer, its ser-
vice agent or similarly qua-
lified persons in order to
avoid a hazard.
Do not connect air condi-
tioner to multi-purpose soc-
ket. Otherwise, it may cau-
se fire hazard.
Do disconnect power supp-
ly when cleaning air condi-
tioner. Otherwise, it may
cause electric shock.
Do not wash the air condi-
tioner with water to avoid
electric shock.
Do not spray water on in-
door unit. It may cause ele-
ctric shock or malfunction.
Do not repair air condition-
er by yourself. It may cause
electric shock or damage.
Please contact dealer when
you need to repair air con-
ditioner.
After removing the filter, do
not touch fins to avoid in-
jury.
Do not extend fingers or
objects into air inlet or air
outlet. It may cause person-
al injury or damage.

CAUTION
Do not spill water on the re-
mote controller, otherwise
the remote controller may
be broken.
Do not use fire or hair dry-
er to dry the filter to avoid
deformation or fire hazard.
Do not block air outlet or
air inlet. It may cause mal-
function.
Do not step on top panel of
outdoor unit, or put heavy
objects. It may cause dam-
age or personal injury.
When below phenomenon
occurs, please turn off air
conditioner and disconnect
power immediately, and
then contact the dealer or
qualified professionals for
service.

WARNING
Please contact the local agent for installation.
Don’t use unqualified power cold.
When installing the unit, make sure that co-
nnection pipe is securely connected before
the compressor starts running.
If compressor starts running when stop valve
is open and connection pipe is not yet conne-
cted, air will be sucked in and cause pressure
rise or compressor rupture, resulting in injury.
WARNING
Prohibit installing the unitat the place where
there may be leaked corrosive gas or flamm-
able gas.
If there is leaked gas around the unit, it may
cause explosion and other accidents.
Do not use extension cords for electrical co-
nnections. If the electric wire is not long eno-
ugh, please contact a local service center au-
thorized and ask for a proper electric wire.
Poor connections may lead to electric shock or fire.

serious safety accident.
sure that the unit is running in cooling mode.
Then, fully close the valve at high pressure
side (liquid valve). About 30-40 secondslater,
fully close the valve at low pressure side
(gas valve), immediately stop the unit and
disconnect power. Please note that the time
for refrigerant recovery should not exceed
1 minute.

Use the specified types of wires for electrical
connections between the indoor and outdoor
units. Firmly clamp the wires so that their te-
rminals receive no external stresses.
If refrigerant recovery takes toomuch time,
air may be sucked in and cause pressure
rise or compressor rupture, resulting in injury.
During refrigerant recovery, make sure that
liquid valve and gas valve are fully closed
and power is disconnected before detachi-
ng the connection pipe.
If compressor starts running when stop valve
is open and connection pipe is not yet conn-
ected, air will be sucked in and cause pressure
rise or compressor rupture, resulting in injury.

amount per meter is different according to the
diameter of liquid pipe. See the following sheet.
Confirm the pipe length according to the distance
