according to ambient temperature.
2.Protection function
a. During cooling operation, protection function is same as that under cooling mode.
b. During heating operation, protection function is same as that under heating mode.
3. Display: Set temperature is the set value under each condition. Ambient temperature is (Tamb.-Tcompensation) for heat pump unit
and Tamb. for cooling only unit.
4. If theres I feel function, Tcompensation is 0. Others are same as above.
(5)Fan mode
Under this mode, indoor fan operates at set fan speed. Compressor, outdoor fan, 4-way valve and electric heating tube stop operation.
Indoor fan can select to operate at high, medium, low or auto fan speed. Temperature setting range is 16~30OC.
2. Other control

Technical Information
11
Service Manual
(8)Off-peak energization function:
Adjust compressors minimum stop time. The original minimum stop time is 180s and then we change to:
The time interval between two start-ups of compressor cant be less than 180+T s(0≤T≤15). T is the variable of controller. Thats to say
the minimum stop time of compressor is 180s~195s. Read-in T into memory chip when refurbish the memory chip each time. After power
recovery, compressor can only be started up after 180+T s at least.
(9) SE control mode
The unit operates at SE status.
(10) X-fan mode
When X-fan function is turned on, after turn off the unit, indoor fan will still operate at low speed for 2min and then the complete unit will be
turned off. When x-fan function is turned off, after turn off the unit, the complete unit will be turned off directly.
(11) 8ºC heating function
Under heating mode, you can set 8ºC heating function by remote controller. The system will operate at 8ºC set temperature.
(12) Turbo fan control function
Set turbo function under cooling or heating mode to enter into turbo fan speed. Press fan speed button to cancel turbo wind.
No turbo function under auto, dry or fan mode.

7. Notes for Installation and Maintenance
Safety Precautions:
Important!
Please read the safety precautions carefully before
installation and maintenance.
The following contents are very important for installation
and maintenance.
Please follow the instructions below.
●The installation or maintenance must accord with the
instructions.
●Comply with all national electrical codes and local
electrical codes.
●Pay attention to the warnings and cautions in this
manual.
●All installation and maintenance shall be performed by
distributor or qualied person.
●All electric work must be performed by a licensed
technician according to local regulations and the
instructions given in this manual.
●Be caution during installation and maintenance. Prohibit
incorrect operation to prevent electric shock, casualty and
other accidents.
Warnings
Electrical Safety Precautions:
1. Cut off the power supply of air conditioner before
checking and maintenance.
2. The air condition must apply specialized circuit and
prohibit share the same circuit with other appliances.
3. The air conditioner should be installed in suitable
location and ensure the power plug is touchable.
4. Make sure each wiring terminal is connected firmly
during installation and maintenance.
5. Have the unit adequately grounded. The grounding wire
cant be used for other purposes.
6. Must apply protective accessories such as protective
boards, cable-cross loop and wire clip.
7. The live wire, neutral wire and grounding wire of power
supply must be corresponding to the live wire, neutral
wire and grounding wire of the air conditioner.
8. The power cord and power connection wires cant be
pressed by hard objects.
9. If power cord or connection wire is broken, it must be
replaced by a qualied person.
10. If the power cord or connection wire is not long enough,
please get the specialized power cord or connection wire
from the manufacture or distributor. Prohibit prolong the wire
by yourself.
11. For the air conditioner without plug, an air switch must
be installed in the circuit. The air switch should be all-pole
parting and the contact parting distance should be more than
1/8 inch.
12. Make sure all wires and pipes are connected properly and
the valves are opened before energizing.
13. Check if there is electric leakage on the unit body. If yes,
please eliminate the electric leakage.
14. Replace the fuse with a new one of the same specication
if it is burnt down; dont replace it with a cooper wire or
conducting wire.
15. If the unit is to be installed in a humid place, the circuit
breaker must be installed.
Installation Safety Precautions:
1. Select the installation location according to the requirement of this manual.(See the requirements in installation
part)
2. Handle unit transportation with care; the unit should not
be carried by only one person if it is more than 44.09lb.
3. When installing the indoor unit and outdoor unit, a sufcient xing bolt must be installed; make sure the installation
support is rm.
4. Ware safety belt if the height of working is above 78 3/4
inch.
5. Use equipped components or appointed components during installation.
6. Make sure no foreign objects are left in the unit after nishing installation.
Refrigerant Safety Precautions:
1. Avoid contact between refrigerant and re as it generates
poisonous gas; Prohibit prolong the connection pipe by
welding.
2. 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 or other hazards.
3. Make sure no refrigerant gas is leaking out when installation
is completed.
4. If there is refrigerant leakage, please take sufcient measure
to minimize the density of refrigerant.
5. Never touch the refrigerant piping or compressor without
wearing glove to avoid scald or frostbite.
Improper installation may lead to re hazard, explosion,
electric shock or injury.

Service Manual
Safety Precautions for Installing and Relocating the Unit:
To ensure safety, please be mindful of the following precautions.
Warnings
1. When installing or relocating the unit, be sure to keep the refrigerant circuit free from air or substances other than the
specied 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
unqualied 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.
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 specied 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 insufcient capacity, wrong wire connections and insecure wire terminals may cause electric shock or re.
