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.

If it needs to install, move or maintain the air conditioner, please contact dealer or local service
center to conduct it at first. Air conditioner must be installed, moved or maintained by appointed
unit. Otherwise, it may cause serious damage or personal injury or death.

WARNING：

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.

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

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 operation of flammable refrigerant

Filling the refrigerant

Safety instructions for transportation and storage

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.

Use the refrigerant filling appliances specialized for R32. Make sure that different

kinds of refrigerant won’t contaminate with each other.

After filling is finished, please do the leakage detection before test running; another

time of leak detection should be done when it’s removed.

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.

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.

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.

Safety precautions for installing and relocating the unit

1. There should be no obstruction near air inlet .

2. Select a location where the condensation water can be dispersed easily and
won't affect other people.

3. Select a location which is convenient to connect the outdoor unit and near the
power socket.

4. Select a location which is out of reach for children.

5. The location should be able to withstand the weight of indoor unit and won't
increase noise and vibration.

6. The appliance must be installed 2.5m above floor.

7. Don't install the indoor unit right above the electric appliance.

8. Please try your best to keep way from fluorescent lamp.

Installation of indoor unit

Step one: choosing installation location

Step two: install wall-mounting frame

rm it with the client.

1. Hang the wall-mounting frame on the wall; adjust it in horizontal position with the

plastic expansion particles in the holes.

3. Fix the wall-mounting frame on the wall with tapping screws (ST4.2X25TA) and

.

1. Choose the position of piping hole according to the direction of outlet pipe. The
position of piping hole should be a little lower than the wall-mounted frame,
shown as below.

Step three: open piping hole

2. Open a piping hole with the diamete

cording to actual wall-mounted plate.

Note: Please select the corresponding installation dimensional drawing ac-

r of Φ55 on the selected outlet pipe

position. In order to drain smoothly, slant the piping hole on the wall slightly
downward to the outdoor side with the gradient of 5-10°.
