Safety Precautions
1. Safety Precautions
Installing, starting up, and servicing air conditioner can behazardous due to system pressure, electrical components, and
equipment location, etc.Only trained, qualied installers and service personnel areallowed to install, start-up, and service this
equipment.Untrained personnel can perform basic maintenance fun-ctions such as cleaning coils. All other operations should be
performed by trained service personnel.When handling the equipment, observe precautions in themanual and on tags, stickers,
and labels attached to theequipment. Follow all safety codes. Wear safety glasses andwork gloves. Keep quenching cloth
and re extinguisher nearby when brazing.Read the instructions thoroughly and follow all warnings orcautions in literature and
attached to the unit. Consult localbuilding codes and current editions of national as well as local electrical codes.
Recognize the following safety information:
◆ Make sure the outdoor unit is installed on a stable, level surface with no accumulation of snow, leaves, or trash beside.
◆ Make sure the ceiling/wall is strong enough to bear the weight of the unit.
◆ Make sure the noise of the outdoor unit does not disturb neighbors.
◆ Follow all the installation instructions to minimize the risk of damage from earth quakes, typhoons or strong winds.
◆ Avoid contact between refrigerant and re as it generate spoisonous gas.
◆ Apply specied refrigerant only. Never have it mixed with any other refrigerant. Never have air remain in the refrigerant line as
it may lead to rupture and other hazards.
◆ Make sure no refrigerant gas is leaking out when installation is completed.
◆ Should there be refrigerant leakage, the density of refrigerant in the air shall in no way exceed its limited value, or it may lead
to explosion.
◆ Keep your ngers and clothing away from any moving parts.
◆ Clear the site after installation. Make sure no foreign objects are left in the unit.
◆ Always ensure effective grounding for the unit.
Incorrect handling could result inpersonal injury or death. Incorrect handling may result inminor injury,or damage to product
or property.
Warning Caution
Warning Caution
All electric work must be performed by a licensed technician
according to local regulations and the instructions given in
this manual.
Before installing, modifying, or servicing system,
mainelectrical disconnect switch must be in the OFF position.
There may be more than 1 disconnect switch. Lock out and
tag switch with a suitable warning label.
Never supply power to the unit unless all wiring and tubing
are completed, reconnected and checked.
This system adopts highly dangerous electrical voltage.
Incorrect connection or inadequate grounding can cause
personal injury or death. Stick to the wiring diagram and all
the instructions when wiring.
Have the unit adequately grounded in accordance with local
electrical codes.
Have all wiring connected tightly. Loose connection may lead
to overheating and a possible re hazard.
All installation or repair work shall be performed by your
dealer or a specialized subcontractor as there is the risk of
re, electric shock, explosion or injury.
Never install the unit in a place where a combustible gas
might leak, or it may lead to re or explosion.
Make a proper provision against noise when the unit is
installed at a telecommunication center or hospital.
Provide an electric leak breaker when it is installed in a
watery place.
Never wash the unit with water.
Handle unit transportation with care. The unit should not be
carried by only one person if it is more than 20kg.
Never touch the heat exchanger ns with bare hands.
Never touch the compressor or refrigerant piping without
wearing glove.
Do not have the unit operate without air lter.
Should any emergency occur, stop the unit and disconnect
the power immediately.
Properly insulate any tubing running inside the room to
prevent the water from damaging the wall.

Safety Precautions
Safety Precautions
Please read this operating manual carefully before operating the unit.
Appliance filled with flammable gas R32.
Before use the appliance, read the owner's manual first.
Befoer install the appliance,read the installation manual first.
Befoer repair the appliance ,read the service manual first.
The figures in this manual may be different with the material objects ,please refer to the material objects for reference.
To realize the function of the air conditioner unit, a special refrigerant circulates in the system.The used refrigerant is the fluoride
R32,which is specially cleaned.The refrigerant is flammable and inodorous. Furthermore,it can leads to explosion under certain
condition.But the flammability of the refrigerant is very low. It can be ignited only by fire.
Compared to common refrigerants, R32 is a nonpolluting refrigerant with no harm to the ozonosphere.The influence upon the
greenhouse effect is also lower. R32 has got very good thermodynamic features which lead to a really high energy efficiency. The units
therefore need a less filling.
The Refrigerant
WARNING:
Do not use means to accelerate the defrosting process or to clean, other than those recommended by the manufacture.Should repair
be necessary, contact your nearest authorized Service Center.
Any repairs carried out by unqualified personnel may be dangerous.
The appliance shall be stored in a room without continuously operating ignition sources.
(For example: open flames, an operating gas appliance or an operating electric heater.)
Do not pierce or burn.
Appliance shall be installed, operated and stored in a room with a floor area larger than
"X"m2(see table 1).(only applies to appliances that are not fixed appliances)
Appliance filled with flammable gas R32. For repairs,strictly follow manufacturer's
instructions only.
Be aware that refrigerants not contain odour.
Read specialist’s manual.
