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 uoride R32, which is specially cleaned. The refrigerant is
ammable 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 inuence 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.

Safety precaution
1. Must follow the electric safety regulations when installing the unit.
2. According to the local safety regulations, use qualied power supply circuit and circuit
break.
3. Make sure the power supply matches with the requirement of air conditioner. Unstable
power supply or incorrect wiring or malfunction. Please install proper power supply cables
before using the air conditioner.
4. Properly connect the live wire, neutral wire and grounding wire of power socket.
5. Be sure to cut off the power supply before proceeding any work related to electricity and
safety.
6. Do not connect the power before nishing inatallation.
7. 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.
8. The temperature of refrigerant circuit will be high, please keep the interconnection cable
away from the copper tube.
9. The appliance shall be installed in accordance with national wiring regulations.
10. Installation must be performed in accordance with the requirement of NEC and CEC by
authorized personnel only.
11. Appliance shall be installed, operated and stored in a room with a oor area larger than
“X”m2 (see table 1).
Please notice that the unit is filled with flammable gas R32. Inappropriate
treatment of the unit involves the risk of severe damages of people
andmaterial. Details to this refrigerant are found in chapter "refrigerant".

16
Installation prepare
1. When installing or relocating the unit, be sure to keep the refrigerant circuit free
from air or substances other than the specied 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 unqualied 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.
4. 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.
To ensure safety, please be mindful of the following precautions.
WARNING
Safety precautions for installing and relocating the unit
Grounding requirement
1. The air conditioner is the rst class electric appliance. It must be properly grounding with
specialized grounding device by a professional. Please make sure it is always grounded
effectively, otherwise it may cause electric shock.
2. The yellow-green wire in air conditioner is grounding wire, which can't be used for other
purposes.
3. The grounding resistance should comply with national electric safety regulations.
4. The appliance must be positioned so that the plug is accessible.
5. An all-pole disconnection switch having a contact separation of at least 3mm in all poles
should be connected in xed wiring. For models with a power plug, make sure the plug is
within reach after installation.

17
5. 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.
6. Prohibit installing the unit at the place where there may be leaked corrosive gas or
ammable gas.
— If there leaked gas around the unit, it may cause explosion and other accidents.
7. 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 re.
8. Use the specied 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 insufcient capacity, wrong wire connections and insecure wire
terminals may cause electric shock or re.

Step 1: Choosing installation location
Recommend the installation location to the client and then conrm it with the client.
Step 2: Install wall-mounting frame
1. Hang the wall-mounting frame on the wall; adjust it in horizontal position with the level
meter and then point out the screw xing holes on the wall .
2. Drill the screw xing holes on the wall with impact drill (the specication of drill head
should be the same as the plastic expansion particle) and then ll the plastic expansion
particles in the holes.
3. Fix the wall-mounting frame on the wall with tapping screws (ST4.2X25TA) and then
check if the frame is rmly inatalled by pulling the frame. If the plastic expansion particle
is loose, please drill another xing hole nearby.
Step 3: Open piping hole
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.
