Safety Precautions
2. Safety Precautions
Installing, starting up, and servicing air conditioner can be hazardous due to system pressure, electrical components, and
equipment location, etc.Only trained, qualied installers and service personnel are allowed to install, start-up, and service this
equipment.Untrained personnel can perform basic maintenance functions such as cleaning coils. All other operations should be
performed by trained service personnel.When handling the equipment, observe precautions in the manual and on tags, stickers,
and labels attached to the equipment. Follow all safety codes. Wear safety glasses and work gloves. Keep quenching cloth
and re extinguisher nearby when brazing.Read the instructions thoroughly and follow all warnings or cautions in literature and
attached to the unit. Consult local building 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 specied 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
Please read this operating manual carefully before operating the unit.
Appliance lled with ammable gas R32.
Before use the appliance, read the owner's manual rst.
Befoer install the appliance,read the installation manual rst.
Befoer repair the appliance ,read the service manual rst.
The gures 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 ammability of the refrigerant is very low. It can be ignited only by re.
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 efciency. The units
therefore need a less lling.
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 unqualied personnel may be dangerous.
The appliance shall be stored in a room without continuously operating ignition sources.
(For example: open ames, 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 oor area larger than
"X"m2(see table 1).(only applies to appliances that are not xed appliances)
Appliance lled with ammable gas R32. For repairs,strictly follow manufacturer's
instructions only.
Be aware that refrigerants not contain odour.
Read specialist’s manual.

4.Warning: Before obtaining access to terminals, all supply circuits must be disconnected.
5.For appliances with type Y attachment, the instructions shall contain the substance of the following. If the supply cord is
damaged, it must be replaced by the manufacturer, its service agent or similarly qualied persons in order to avoid a hazard.
6.The appliance must be positioned so that the plug is accessible.
7.The temperature of refrigerant line will be high; please keep the interconnection cable away from the copper tube.
8.The instructions shall state the substance of the following:This appliance is not intended for use by persons(including
children)with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been
given supervision or instruction concerning use of the appliance by a person responsible for their safety.
Children should be supervised to ensure that they do not play with the appliance.
9. Appliance shall be installed, operated and stored in a room with a oor area larger than "X"m2(see table 1).
1. When installing or relocating the unit, be sure to keep the refrigerant circuit free from air or substances other than the
specified refrigerant.
— Any presence of air or other foreign substance in the refrigerant circuit will cause system pressure rise or compressor rupture,
resulting in injury.
2. When installing or moving this unit, do not charge the refrigerant which is not comply with that on the nameplate or
unqualified refrigerant.
— Otherwise, it may cause abnormal operation, wrong action, mechanical malfunction or even series safety accident.
3. When refrigerant needs to be recovered during relocating or repairing the unit, be sure that the unit is running in cooling
mode.Then, fully close the valve at high pressure side (liquid valve).About 30-40 seconds later, 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.
— If refrigerant recovery takes too much time, air may be sucked in and cause pressure rise or compressor rupture, resulting in injury.
