* The protective function might work when using it outside the temperature range mentioned above.
Acoustic Noise Information: The maximum sound pressure level is less than 70 dB (A) for both indoor unit and outdoor unit.
According to IEC 704-1 and ISO 3744.
If the air conditioner is operated under higher temperature conditions than those listed, the built-in protection circuit may operate to prevent internal circuit damage. Also, during Cooling and Dry modes, if the unit is used under conditions of lower temperatures than those listed above, the heat-exchanger may freeze, leading to water leakage and other damage.
If the unit is used for long periods under high-humidity conditions, condensation may form on the surface of the indoor unit, and drip onto the floor or other objects underneath.

WARNING or CAUTION.
Appliance filled with flammable gas R32.
Before use the appliance, read the owner’s manual first.
Before install the appliance, read the installation manual first.
Before repair the appliance, read the service manual first.
The Refrigerant
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 conditions. 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.
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 Centre. 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 m .
(Please refer to table "a" in section of " Safety Operation of Inflammable
Refrigerant" for Space X.)
Appliance filled with flammable gas R32. For repairs, strictly follow manufacturer’s instructions only. Be aware that refrigrants not contain odour. Read specialist’s manual.

Safety precautions for installing and relocating the unit
To ensure safety, please be mindful of the following precautions.
Warning
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.
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.
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.
During refrigerant recovery, make sure that liquid valve and gas valve are fully closed and power is disconnected before detaching the connection pipe.
If compressor starts running when stop valve is open and connection pipe is not yet connected, air will be sucked in and cause pressure rise or compressor rupture, resulting in injury.
When installing the unit, make sure that connection pipe is securely connected before the compressor starts running.
If compressor starts running when stop valve is open and connection pipe is not yet connected, air will be sucked in and cause pressure rise or compressor rupture, resulting in injury.
Prohibit installing the unit at the place where there may be leaked corrosive gas or flammable gas.
If there leaked gas around the unit, it may cause explosion and other accidents.
Do not use extension cords for electrical connections. If the electric wire is not long enough, please contact a local service center authorized and ask for a proper electric wire.
Poor connections may lead to electric shock or fire.
Use the specified types of wires for electrical connections between the indoor and outdoor units. Firmly clamp the wires so that their terminals receive no external stresses.
Electric wires with insufficient capacity, wrong wire connections and insecure wire terminals may cause electric shock or fire.

4. The calculation method of additional refrigerant oil and refrigerant charging amount after prolonging connection pipe
After the length of connection pipe is prolonged for 10m at the basis of standard length, you should add 5ml of refrigerant oil for each additional 5m of connection pipe.
The calculation method of additional re f rigerant charging amount (on the basis of liquid pipe):
(1) Additional refrigerant charging amount= prolonged length of liquid pipe × additional
(2) refrigerant charging amount per meter
Basing on the length of standard pipe, add refrigerant according to the requirement as shown in the table. The additional refrigerant charging amount
per meter is di f ferent according to the diameter of liquid pipe. See Sheet 2.

Safety operation of flammable refrigerant
Qualification requirement for installation and maintenance man
All the work men who are engaging in the refrigeration system should bear the valid certification awarded by the authoritative organization and the qualification for dealing with the refrigeration system recognized by this industry. If it needs other technician to maintain and repair the appliance, they should be supervised by the person who bears the qualification for using the flammable refrigerant.
It can only be repaired by the method suggested by the equipment’s manufacturer.
Installation notes
The air conditioner is not allowed to use in a room that has running fire (such as fire source, working coal gas ware, operating heater).
It is not allowed to drill hole or burn the connection pipe.
The air conditioner must be installed in a room that is larger than the minimum room area. The minimum room area is shown on the nameplate or following table a.
Leak test is a must after installation.

Welding
If you should cut or weld the refrigerant system pipes in the process of maintaining, please follow the steps as below:
3 9
Safety operation of flammable refrigerant
a. Shut down the unit and cut power supply b. Eliminate the refrigerant c. Vacuuming d. Clean it with N2 gas e. Cutting or welding f. Carry back to the service spot for welding
The refrigerant should be recycled into the specialized storage tank.
Make sure that there isn’t any naked flame near the outlet of the vacuum pump and it’s well-ventilated.
Filling the refrigerant
Use the refrigerant filling appliances specialized for R32. Make sure that different kinds of refrigerant won’t contaminate with each other.
The refrigerant tank should be kept upright at the time of filling refrigerant.
Stick the label on the system after filling is finished (or haven’t finished).
Don’t overfilling.
After filling is finished, please do the leakage detection before test running; another time of leak detection should be done when it’s removed.
Safety instructions for transportation and storage
Please use the flammable gas detector to check before unload and open the container.
No fire source and smoking.
According to the local rules and laws.
