Chapter 2 Operating Principle
. Cooling
After the power supply is switched on, the machine is set to COOL mode. With the compressor being operated, the low-temperature and low-pressure refrigerant vapor is sucked into the compressor where it is

turned into high-temperature and high-pressure gas. Then it is cooled down in the outdoor heat exchanger by the air and becomes liquid. After being throttled by the capillary, the refrigerant liquid comes into the indoor unit and then it evaporates in the indoor heat, exchanger, absorbing heat and reducing the room temperature. The evaporated refrigerant vapor returns to the outdoor unit and is again sucked into the compressor, completing the cycle. With the refrigerant cycling being kept on, the objective of lowering the room temperature is fulfilled.
. Heating
After the power supply is switched on, the machine is set to HEAT mode and the coil of the electromagnetic four-way valve is energized. After the compressor starts to operate, the high-temperature and high-pressure refrigerant gas first comes into the heat exchanger of the indoor unit, where it is cooled, releases heat and increases the room temperature. The cooled high-pressure refrigerant is then throttle1d in the outdoor unit and returns to the compressor after evaporation. With such cycles being maintained, the objective of increasing the room temperature is fulfilled.

Operation Hints
Adjust room temperature properly. Set the temperature 1^ higher than actually desired. Approximately 10% of electricity costs can be saved.
Clean the air filter regularly. Blockage in the air filter reduces the airflow and lowers the cooling. Clean at least once every 2 weeks. Otherwise, 6% of electricity cost will be wasted.


Prevent waste with the Timer. Use Timer when sleeping or going out to save electricity cost.
Do not block the air outlet vents at outdoor unit. Otherwise, it will lower the cooling performance.


Make sure that the doors and windows are shut. Otherwise, cooling performance will be reduced and electricity cost is wasted.
Keep blinds or curtains closed. Do not let sunshine enter the room directly. 5% of electricity cost can be saved.


Proper airflow direction adjustment. Set the airflow direction louvers horizontal for Cooling Operation. Operation result will be better.
Use insulating material for better performance. Use insulating material during construction or renovations. It will save electricity cost.


Chapter 3 operation details
1. Overall
1.1 Protection of compressor
Whatever operation modes the air-conditioner is under, there will always be 3 minutes' time-delay protection unless it is on for the first time. When the compressor is switched on, it can not be shut down within 3 minutes (except under the modes of heating or defrosting) unless it is powered off or its operation mode is changed.
1.2 The operation indicator will turn light when the air conditioner is powered on.
1.3 The buzzer will sound immediately after the controlling device receives a correct and effective signal sent by the remote control.
1.4 Timing function can be applicable to all operation modes while sleep function can only be applicable to the modes of refrigeration and heating.
2. Automatic operation mode
2.1 When the air conditioner works, it can detect the indoor temperature automatically whereby its operation mode can be selected: refrigeration, heating or dehumidification.
2.2 When the indoor temperature reaches more than 27, the air conditioner will operate under the mode of refrigeration.
2.3 When the indoor temperature reaches between 20 and 27 the air
conditioner will work under the mode of dehumidification (always mute).
2.4 When the indoor temperature reaches less than 20, the air conditioner will work under the mode of heating.
2.5 Under this mode, the air conditioner will operate in the respect of blowing rate as set and its pendulum leaves will work according to the requirements of automatic ventilation door.
2.6 Once the operation mode is selected, it will not be able to be changed. When the air conditioner is shut down and then restarted, the operation mode will be selected once again based on the variation of indoor temperature.
2.7 After the operation indicator has been flickering for 20 seconds, it will turn light steadily (i.e. the determination of operation mode will start in 20 seconds.)
2.8 This mode has timing function, does not have sleep function.
2.9 Under this operation mode, the temperature can be set and adjusted by remote control.
3. Refrigeration mode
3.1 Under the refrigeration mode, the range of temperature set by remote control is between 16 and 32.
3.2 Shut-down of four-way valve;
3.3 The condition on which the compressor starts is that the indoor
temperature reaches more than the temperature set plus 1 while the condition on which the compressor shuts down is that the indoor temperature reaches less than the temperature set minus 1 .And when the indoor temperature is equal to that set, the original operation mode will be kept.
3.4 Under the mode of refrigeration, the function of preventing indoor coiled pipe from being frozen will be effective.
3.5 The indoor wind speed will be as set. And the pendulum leaves will work according to the instructions sent by remote control.
4. Dehumidification operation
4.1 The temperature range set and controlled is between 16 and 32 . The temperature will be set by remote control.
4.2 The four-way valve is shut down.
4.3 The wind speed gear-changes to "mute". And the pendulum leaves works according to the instructions sent by remote control;
4.4 The function of preventing indoor coiled pipe from being frozen is effective.
4.5 When the indoor temperature reaches less than 16, the function of dehumidification is out of use.
4.6 When the indoor temperature reaches more than 16, the compressor will be switched on and work intermittently. The time when the compressor shuts down depends on T ring and T ring-T set.
When the compressor is shut down, the outdoor fan and indoor fan will stop working.
When T ring ≥ 23
T set < T ring-1, the compressor will be working for 8 minutes and then stopping for 3 minutes in cycles.
T set≥T ring-1, the compressor will be working for 3 minutes and then stopping for 6 minutes in cycles.
And when T ring < 23
T set ≤ T ring-1, the compressor will be working for 3 minutes and then stopping for 4 minutes in cycles.
T set >T ring-1, the compressor will be working for 3 minutes and then stopping for 6 minutes in cycles.
5. Function of ventilation control
5.1 Under the mode of ventilation, the outdoor fan assembly will always be shut down.
5.2 The indoor fan will operate as set in the respect of air quantity without the gear- change of "high power".

6. Heating function
6.1 Under the mode of heating, the temperature range set is between 16 and 32. And the temperature will be set by remote control.
6.2 When the air conditioner is powered on, the outdoor fan, four- way valve and compressor will start at the same time while when it is shut down, the outdoor fan and compressor will be shut down at the same time and so will the four- way valve after 2 minutes' delay.
6.3 Under the mode of heating, the compressor can not be shut down within 3 minutes after it is powered on unless the operation mode is changed or the air conditioner is turned off.
6.4 There is a 3-temperature compensating function. The temperature measured at the in-blow vent minus 3 automatically can be regarded as that compared with the temperature set (This function does not exist under other circumstances).
6.5 According to the temperature set, the condition upon which the compressor will be switched on is indoor temperature ≤ temperature set-1 While the condition upon which it will be switched off is indoor temperature is indoor temperature ≥ temperature + 1 . When the indoor temperature is equal to that set, the original operation mode will be kept.

Chapter 8 Fault Analysis of the Product Available and
Typical Examples
1 Procedure of deciding the faults
Before maintaining the air conditioner, firstly you should know the phenomena of the faults, decide the location of the faults, analyze the reason the faults occur, and then search for ways to solve the faults. The detailed procedures are: Look, Listen, Touch, Measure, Analyze
Look: Observe air conditioner's running. I.e., vibration; condensation on evaporator; leakage; electrical and mechanical connection, etc.
Listen: Listen to kinds of sounds of the running air conditioner. Identify the abnormal noise from the sounds.
Touch: Touch the key position and position faulty. Touch the temp of air circulation to decide the heating or cooling effect; as far to abnormal sound, besides adopt "listen", you should touch the frame, the pipe of the air conditioner to feel the vibration. Touch the easily heated parts, i.e. compressor, motor, touch them to feel the temp.(Warning: High temp).
Measure: Measure the parameters of the air conditioner and relevant parts by some instruments. Usually used instruments: amperometer, voltmeter multimeter thermometer, etc, i.e., Use multimeter to test whether the capacitor is open, the insulation of the wire and the parameters of other electrical parts; use the thermometer to measure temp of airflow.
Analyze: Analyze the above results, decide the reason and location
of faults, and seek the solutions.
2 Types of Normal Faults
The type of faults is various. The normal faults can come down to six types: leaks, block, open circuit, burnt, lock, scrape.
Leak Mainly is leakage of R407C from cooling pipe system and parts; leakage of condensation water from indoor units; electrical leakage from electrical system and wires.
Block Mainly is block of the pipe system, block of capillary, block of strainer or valve.
Open Circuit Mainly is open circuit of electrical circuit, include: fuse blowing out, connectors broke.
Burnt Mainly is burnout of fan motor, of compressor, of capacitor, of transformer.
Lock Mainly is lock of compressor, four-way valve.
Scrape Mainly is scrape of indoor/outdoor fan and nearby parts, and sound abnormally.

Chapter 2 Operating Principle
. Cooling
After the power supply is switched on, the machine is set to COOL mode. With the compressor being operated, the low-temperature and low-pressure refrigerant vapor is sucked into the compressor where it is turned into high-temperature and high-pressure gas. Then it is cooled down in the outdoor heat exchanger by the air and becomes liquid. After being throttled by the capillary, the refrigerant liquid comes into the indoor unit and then it evaporates in the indoor heat, exchanger,

absorbing heat and reducing the room temperature. The evaporated refrigerant vapor returns to the outdoor unit and is again sucked into the compressor, completing the cycle. With the refrigerant cycling being kept on, the objective of lowering the room temperature is fulfilled.
. Heating
After the power supply is switched on, the machine is set to HEAT mode and the coil of the electromagnetic four-way valve is energized. After the compressor starts to operate, the high-temperature and high-pressure refrigerant gas first comes into the heat exchanger of the indoor unit, where it is cooled, releases heat and increases the room temperature. The cooled high-pressure refrigerant is then throttle1d in the outdoor unit and returns to the compressor after evaporation. With such cycles being maintained, the objective of increasing the room temperature is fulfilled.

Operation Hints
Adjust room temperature properly. Set the temperature 1^ higher than actually desired. Approximately 10% of electricity costs can be saved.
Clean the air filter regularly. Blockage in the air filter reduces the airflow and lowers the cooling. Clean at least once every 2 weeks. Otherwise, 6% of electricity cost will be wasted.


Prevent waste with the Timer. Use Timer when sleeping or going out to save electricity cost.
Do not block the air outlet vents at outdoor unit. Otherwise, it will lower the cooling performance.


Make sure that the doors and windows are shut. Otherwise, cooling performance will be reduced and electricity cost is wasted.
Keep blinds or curtains closed. Do not let sunshine enter the room directly. 5% of electricity cost can be saved.


Proper airflow direction adjustment. Set the airflow direction louvers horizontal for Cooling Operation. Operation result will be better.
Use insulating material for better performance. Use insulating material during construction or renovations. It will save electricity cost.


Chapter 3 operation details
1. Overall
1.1 Protection of compressor
Whatever operation modes the air-conditioner is under, there will always be 3 minutes' time-delay protection unless it is on for the first time. When the compressor is switched on, it can not be shut down within 3 minutes (except under the modes of heating or defrosting) unless it is powered off or its operation mode is changed.
1.2 The operation indicator will turn light when the air conditioner is powered on.
1.3 The buzzer will sound immediately after the controlling device receives a correct and effective signal sent by the remote control.
1.4 Timing function can be applicable to all operation modes while sleep function can only be applicable to the modes of refrigeration and heating.
2. Automatic operation mode
2.1 When the air conditioner works, it can detect the indoor temperature automatically whereby its operation mode can be selected: refrigeration, heating or dehumidification.
2.2 When the indoor temperature reaches more than 27, the air conditioner will operate under the mode of refrigeration.
2.3 When the indoor temperature reaches between 20 and 27 the air
conditioner will work under the mode of dehumidification (always mute).
2.4 When the indoor temperature reaches less than 20, the air conditioner will work under the mode of heating.
2.5 Under this mode, the air conditioner will operate in the respect of blowing rate as set and its pendulum leaves will work according to the requirements of automatic ventilation door.
2.6 Once the operation mode is selected, it will not be able to be changed. When the air conditioner is shut down and then restarted, the operation mode will be selected once again based on the variation of indoor temperature.
2.7 After the operation indicator has been flickering for 20 seconds, it will turn light steadily (i.e. the determination of operation mode will start in 20 seconds.)
2.8 This mode has timing function, does not have sleep function.
2.9 Under this operation mode, the temperature can be set and adjusted by remote control.
3. Refrigeration mode
3.1 Under the refrigeration mode, the range of temperature set by remote control is between 16 and 32.
3.2 Shut-down of four-way valve;
3.3 The condition on which the compressor starts is that the indoor
temperature reaches more than the temperature set plus 1 while the condition on which the compressor shuts down is that the indoor temperature reaches less than the temperature set minus 1 .And when the indoor temperature is equal to that set, the original operation mode will be kept.
3.4 Under the mode of refrigeration, the function of preventing indoor coiled pipe from being frozen will be effective.
3.5 The indoor wind speed will be as set. And the pendulum leaves will work according to the instructions sent by remote control.
4. Dehumidification operation
4.1 The temperature range set and controlled is between 16 and 32 . The temperature will be set by remote control.
4.2 The four-way valve is shut down.
4.3 The wind speed gear-changes to "mute". And the pendulum leaves works according to the instructions sent by remote control;
4.4 The function of preventing indoor coiled pipe from being frozen is effective.
4.5 When the indoor temperature reaches less than 16, the function of dehumidification is out of use.
4.6 When the indoor temperature reaches more than 16, the compressor will be switched on and work intermittently. The time when the compressor shuts down depends on T ring and T ring-T set.
When the compressor is shut down, the outdoor fan and indoor fan will stop working.
When T ring ≥ 23
T set < T ring-1, the compressor will be working for 8 minutes and then stopping for 3 minutes in cycles.
T set≥T ring-1, the compressor will be working for 3 minutes and then stopping for 6 minutes in cycles.
And when T ring < 23
T set ≤ T ring-1, the compressor will be working for 3 minutes and then stopping for 4 minutes in cycles.
T set >T ring-1, the compressor will be working for 3 minutes and then stopping for 6 minutes in cycles.
5. Function of ventilation control
5.1 Under the mode of ventilation, the outdoor fan assembly will always be shut down.
5.2 The indoor fan will operate as set in the respect of air quantity without the gear- change of "high power".
5.3 The pendulum leaves will work according to the instructions sent by remote control.
6. Heating function
6.1 Under the mode of heating, the temperature range set is between 16 and 32. And the temperature will be set by remote control.
6.2 When the air conditioner is powered on, the outdoor fan, four- way valve and compressor will start at the same time while when it is shut down, the outdoor fan and compressor will be shut down at the same time and so will the four- way valve after 2 minutes' delay.
6.3 Under the mode of heating, the compressor can not be shut down within 3 minutes after it is powered on unless the operation mode is changed or the air conditioner is turned off.
6.4 There is a 3-temperature compensating function. The temperature measured at the in-blow vent minus 3 automatically can be regarded as that compared with the temperature set (This function does not exist under other circumstances).
6.5 According to the temperature set, the condition upon which the compressor will be switched on is indoor temperature ≤ temperature set-1 While the condition upon which it will be switched off is indoor temperature is indoor temperature ≥ temperature + 1 . When the indoor temperature is equal to that set, the original operation mode will be kept.
6.6 Indoor fan control:

Chapter 8 Fault Analysis of the Product Available and
Typical Examples
1 Procedure of deciding the faults
Before maintaining the air conditioner, firstly you should know the phenomena of the faults decide the location of the faults, analyze the reason the faults occur, and then search for ways to solve the faults. The detailed procedures are: Look, Listen, Touch, Measure, Analyze
Look: Observe air conditioner's running. I.e., vibration; condensation on evaporator; leakage; electrical and mechanical connection, etc.
Listen: Listen to kinds of sounds of the running air conditioner. Identify the abnormal noise from the sounds.
Touch: Touch the key position and position faulty. Touch the temp of air circulation to decide the heating or cooling effect; as far to abnormal sound, besides adopt "listen", you should touch the frame, the pipe of the air conditioner to feel the vibration. Touch the easily heated parts, i.e. compressor, motor; touch them to feel the temp. (Warning: High temp).
Measure: Measure the parameters of the air conditioner and relevant parts by some instruments. Usually used instruments: amperometer, voltmeter multimeter thermometer, etc., i.e., Use multimeter to test whether the capacitor is open, the insulation of the wire and the parameters of other electrical parts; use the thermometer to measure temp of airflow.
Analyze: Analyze the above results, decide the reason and location of faults, and seek the solutions.
2 Types of Normal Faults
The type of faults is various. The normal faults can come down to six types: leaks, block, open circuit, burnt, lock, scrape.
Leak Mainly is leakage of R407C from cooling pipe system and parts; leakage of condensation water from indoor units; electrical leakage from electrical system and wires.
Block Mainly is block of the pipe system, block of capillary, block of strainer or valve.
Open Circuit Mainly is open circuit of electrical circuit, include: fuse blowing out, connectors broke.
Burnt Mainly is burnout of fan motor, of compressor, of capacitor, of transformer.
Lock Mainly is lock of compressor, four-way valve.
Scrape Mainly is scrape of indoor/outdoor fan and nearby parts, and sound abnormally.
3 Examples

Chapter 2 Operating Principle
. Cooling
After the power supply is switched on, the machine is set to COOL mode. With the compressor being operated, the low-temperature and low-pressure refrigerant vapor is sucked into the compressor where it is turned into high-temperature and high-pressure gas. Then it is cooled down in the outdoor heat exchanger by the air and becomes liquid. After being throttled by the capillary, the refrigerant liquid comes into the indoor unit and then it evaporates in the indoor heat, exchanger, absorbing heat and reducing the room temperature. The evaporated refrigerant vapor returns to the outdoor unit and is again sucked into the compressor, completing the cycle. With the refrigerant cycling being kept on, the objective of lowering the room temperature is fulfilled.

. Heating
After the power supply is switched on, the machine is set to HEAT mode and the coil of the electromagnetic four-way valve is energized. After the compressor starts to operate, the high-temperature and high-pressure refrigerant gas first comes into the heat exchanger of the indoor unit, where it is cooled, releases heat and increases the room temperature. The cooled high-pressure refrigerant is then throttled in the outdoor unit and returns to the compressor after evaporation. With such cycles being maintained, the objective of increasing the room temperature is fulfilled.

Operation Hints
Adjust room temperature properly. Set the temperature 1^ higher than actually desired. Approximately 10% of electricity costs can be saved.
Clean the air filter regularly. Blockage in the air filter reduces the airflow and lowers the cooling. Clean at least once every 2 weeks. Otherwise, 6% of electricity cost will be wasted.


Prevent waste with the Timer. Use Timer when sleeping or going out to save electricity cost.
Do not block the air outlet vents at outdoor unit. Otherwise, it will lower the cooling performance.


Make sure that the doors and windows are shut. Otherwise, cooling performance will be reduced and electricity cost is wasted.
Keep blinds or curtains closed. Do not let sunshine enter the room directly. 5% of electricity cost can be saved.


Proper airflow direction adjustment. Set the airflow direction louvers horizontal for Cooling Operation. Operation result will be better.
Use insulating material for better performance. Use insulating material during construction or renovations. It will save electricity cost.


Chapter 3 operation details
1. Overall
1.1 Protection of compressor
Whatever operation modes the air-conditioner is under, there will always be 3 minutes' time-delay protection unless it is on for the first time. When the compressor is switched on, it can not be shut down within 3 minutes (except under the modes of heating or defrosting) unless it is powered off or its operation mode is changed.
1.2 The operation indicator will turn light when the air conditioner is powered on.
1.3 The buzzer will sound immediately after the controlling device receives a correct and effective signal sent by the remote control.
1.4 Timing function can be applicable to all operation modes while sleep function can only be applicable to the modes of refrigeration and heating.
2. Automatic operation mode
2.1 When the air conditioner works, it can detect the indoor temperature automatically whereby its operation mode can be selected: refrigeration, heating or dehumidification.
2.2 When the indoor temperature reaches more than 27, the air conditioner will operate under the mode of refrigeration.
2.3 When the indoor temperature reaches between 20 and 27 the air
conditioner will work under the mode of dehumidification (always mute).
2.4 When the indoor temperature reaches less than 20 , the air conditioner will work under the mode of heating.
2.5 Under this mode, the air conditioner will operate in the respect of blowing rate as set and its pendulum leaves will work according to the requirements of automatic ventilation door.
2.6 Once the operation mode is selected, it will not be able to be changed. When the air conditioner is shut down and then restarted, the operation mode will be selected once again based on the variation of indoor temperature.
2.7 After the operation indicator has been flickering for 20 seconds, it will turn light steadily (i.e. the determination of operation mode will start in 20 seconds.)
2.8 This mode has timing function, does not have sleep function.
2.9 Under this operation mode, the temperature can be set and adjusted by remote control.
3. Refrigeration mode
3.1 Under the refrigeration mode, the range of temperature set by remote control is between 16 and 32.
3.2 Shut-down of four-way valve;
3.3 The condition on which the compressor starts is that the indoor
temperature reaches more than the temperature set plus 1 while the condition on which the compressor shuts down is that the indoor temperature reaches less than the temperature set minus 1 .And when the indoor temperature is equal to that set, the original operation mode will be kept.
3.4 Under the mode of refrigeration, the function of preventing indoor coiled pipe from being frozen will be effective.
3.5 The indoor wind speed will be as set. And the pendulum leaves will work according to the instructions sent by remote control.
4. Dehumidification operation
4.1 The temperature range set and controlled is between 16 and 32 . The temperature will be set by remote control.
4.2 The four-way valve is shut down.
4.3 The wind speed gear-changes to "mute". And the pendulum leaves works according to the instructions sent by remote control;
4.4 The function of preventing indoor coiled pipe from being frozen is effective.
4.5 When the indoor temperature reaches less than 16, the function of dehumidification is out of use.
4.6 When the indoor temperature reaches more than 16, the compressor will be switched on and work intermittently. The time when the compressor shuts down depends on T ring and T ring-T set.
When the compressor is shut down, the outdoor fan and indoor fan will stop working.
When T ring ≥ 23
T set < T ring-1, the compressor will be working for 8 minutes and then stopping for 3 minutes in cycles.
T set≥T ring-1, the compressor will be working for 3 minutes and then stopping for 6 minutes in cycles.
And when T ring < 23
T set ≤ T ring-1, the compressor will be working for 3 minutes and then stopping for 4 minutes in cycles.
T set >T ring-1, the compressor will be working for 3 minutes and then stopping for 6 minutes in cycles.
5. Function of ventilation control
5.1 Under the mode of ventilation, the outdoor fan assembly will always be shut down.
5.2 The indoor fan will operate as set in the respect of air quantity without the gear- change of "high power".

6. Heating function
6.1 Under the mode of heating, the temperature range set is between 16 and 32. And the temperature will be set by remote control.
6.2 When the air conditioner is powered on, the outdoor fan, four- way valve and compressor will start at the same time while when it is shut down, the outdoor fan and compressor will be shut down at the same time and so will the four- way valve after 2 minutes' delay.
6.3 Under the mode of heating, the compressor can not be shut down within 3 minutes after it is powered on unless the operation mode is changed or the air conditioner is turned off.
6.4 There is a 3-temperature compensating function. The temperature measured at the in-blow vent minus 3 automatically can be regarded as that compared with the temperature set (This function does not exist under other circumstances).
6.5 According to the temperature set, the condition upon which the compressor will be switched on is indoor temperature ≤ temperature set-1 While the condition upon which it will be switched off is indoor temperature is indoor temperature ≥ temperature + 1 . When the indoor temperature is equal to that set, the original operation mode will be kept.

Chapter 8 Fault Analysis of the Product Available and
Typical Examples
1 Procedure of deciding the faults
Before maintaining the air conditioner, firstly you should know the phenomena of the faults, decide the location of the faults, analyze the reason the faults occur, and then search for ways to solve the faults. The detailed procedures are: Look, Listen, Touch, Measure, Analyze
Look: Observe air conditioner's running. I.e., vibration; condensation on evaporator; leakage; electrical and mechanical connection, etc.
Listen: Listen to kinds of sounds of the running air conditioner. Identify the abnormal noise from the sounds.
Touch: Touch the key position and position faulty. Touch the temp of air circulation to decide the heating or cooling effect; as far to abnormal sound, besides adopt "listen", you should touch the frame, the pipe of the air conditioner to feel the vibration. Touch the easily heated parts, i.e. compressor, motor, touch them to feel the temp.(Warning: High temp).
Measure: Measure the parameters of the air conditioner and relevant parts by some instruments. Usually used instruments: amperometer, voltmeter multimeter thermometer, etc., i.e., Use multimeter to test whether the capacitor is open, the insulation of the wire and the parameters of other electrical parts; use the thermometer to measure temp of airflow.
Analyze: Analyze the above results, decide the reason and location of faults, and seek the solutions.
2 Types of Normal Faults
The type of faults is various. The normal faults can come down to six types: leaks, block, open circuit, burnt, lock, scrape.
Leak Mainly is leakage of R407C from cooling pipe system and parts; leakage of condensation water from indoor units; electrical leakage from electrical system and wires.
Block Mainly is block of the pipe system, block of capillary, block of strainer or valve.
Open Circuit Mainly is open circuit of electrical circuit, include: fuse blowing out, connectors broke.
Burnt Mainly is burnout of fan motor, of compressor, of capacitor, of transformer.
Lock Mainly is lock of compressor, four-way valve.
Scrape Mainly is scrape of indoor/outdoor fan and nearby parts, and sound abnormally.
3 Examples
3.1 Leakage and seepage of indoor unit
