Mode setting is incorrect, and the temperature and wind speed settings are not appropriate. → Please re-select the mode, and set the appropriate temperature and wind speed.
The indoor unit blows out odor.| The air conditioner itself does not have undesirable odor. If there is odor, it may be due to accumulation of the odor in the environment. → Clean the air filter or activate the cleaning function.
There is sound of running water during the running of air conditioner.| When the air conditioner is started up or stopped, or the compressor is started up or stopped during the running, sometimes the “hissing” sound of running water can be heard. → This is the sound of the flow of the refrigerant, not a malfunction.
A slight “click” sound is heard at the of start-up or shut-down.| Due to temperature changes, panel and other parts will swell, causing the sound of friction. → This is normal, not a fault.
---|---
The indoor unit makes abnormal sound.| The sound of fan or compressor relay switched on or off.
When the defrosting is started or stop running, it will sound. → That is due to the refrigerant flowed to reverse direction. They are not malfunctions.
Too much dust accumulation in the air filter of the indoor unit may result in fluctuation of the sound. → Clean the air filters in time.
Too much air noise when “Strong wind” is turned on. → This is normal, if feeling uncomfortable, please deactivate the “Strong wind” function.
There are water drops over the surface of the indoor unit.| When ambient humidity is high, water drops will be accumulated around the air outlet or the panel, etc. → This is a normal physics phenomenon.
Prolonged cooling run in open space produces water drops. → Close the doors and windows.
Too small opening angle of the louver blades may also result in water drops at the air inlet. → Increase the angle of the louver blades.
During the cooling operation, the indoor unit outlet sometimes will blow out mist.| When the indoor temperature and humidity are high, it happens sometimes. → This is because the indoor air is cooled rapidly. After it runs for some time, the indoor temperature and humidity will be reduced and the mist will disappear.

   No person carrying out work in relation to a refrigeration system which involves exposing any pipe work shall use any sources of ignition in such a manner that it may lead to the risk of fire or explosion. All possible ignition sources, including cigarette smoking, should be kept sufficiently far away from the site of installation, repairing, removing and disposal, during which refrigerant can possibly be released to the surrounding space. Prior to work taking place, the area around the equipment is to be surveyed to make sure that there are no flammable hazards or ignition risks.
   ‘No Smoking’ signs shall be displayed.

5. Ventilated Area(open the door and window):
   Ensure that the area is in the open or that it is adequately ventilated before breaking into the system or conducting any hot work. A degree of ventilation shall continue during the period that the work is carried out. The ventilation should safely disperse any released refrigerant and preferably expel it externally into the atmosphere.

6. Checks to the refrigeration equipment:
   Where electrical components are being changed, they shall be fit for the purpose and to the correct specification. At all times the manufacturer’s maintenance and service guidelines shall be followed. If in doubt, consult the manufacturer’s technical department for assistance. The following checks shall be applied to
   installations using flammable refrigerants:

   • The charge size is in accordance with the room size within which the refrigerant containing parts are installed.
   • The ventilation machinery and outlets are operating adequately and are not obstructed.
   • If an indirect refrigerating circuit is being used, the secondary circuit shall be checked for the presence of refrigerant.
   • Refrigeration pipe or components are installed in a position where they are unlikely to be exposed to any substance which may corrode refrigerant containing components, unless the components are constructed of materials which are inherently resistant to being corroded or are suitably protected against being so corroded.

7. . Checks to electrical devices:
   Repair and maintenance to electrical components shall include initial safety checks and component inspection procedures. If a fault exists that could compromise safety, then no electrical supply shall be connected to the circuit until it is satisfactorily dealt with. If the fault cannot be corrected immediately but it is necessary to continue operation, an adequate temporary solution shall be used. This shall be reported to the owner of the equipment so all parties are advised.
   Initial safety checks shall include:

   • That capacitors are discharged: this shall be done in a safe manner to avoid possibility of sparking.
   • That no live electrical components and wiring are exposed while charging, recovering or purging the system.
   • Keep continuity of earthing.

Inspection of Cable

Check the cable for wear, corrosion, overvoltage, vibration and check if there are sharp edges and other adverse effects in the surrounding environment. During the inspection, the impact of aging or the continuous vibration of the compressor and the fan on it should be taken into consideration.

Leakage check of R32 refrigerant

Note: Check the leakage of the refrigerant in an environment where there is no potential ignition source. No halogen probe (or any other detector that uses an open flame) should be used.
Leak detection method:
For systems with refrigerant R32, electronic leak detection instrument is available to detect and leak detection should not be conducted in environment with refrigerant. Make sure the leak detector will not become a potential source of ignition, and is applicable to the measured refrigerant. Leak detector shall be set for the minimum ignitable fuel concentration (percentage) of the refrigerant. Calibrate and adjust to proper gas concentration (no more than 25%) with the used refrigerant.
The fluid used in leak detection is applicable to most refrigerants. But do not use chloride solvents to prevent the reaction between chlorine and refrigerants and the corrosion of copper pipeline.
If you suspect a leak, then remove all the fire from the scene or put out the fire.
If the location of the leak needs to be welded, then all refrigerants need to be recovered, or, isolate all refrigerants away from the leak site (using cut- off valve). Before and during the welding, use OFN to purify the entire system.

Removal and Vacuum Pumping

1. Make sure there is no ignited fire source near the outlet of the vacuum pump and the ventilation is well.
2. Allow the maintenance and other operations of the refrigeration circuit should be carried out according to the general procedure, but the following best operations that the flammability is already taken into consideration are the key. You should follow the following procedures:
   • Remove the refrigerant.
   • Decontaminate the pipeline by inert gases.
   • Evacuation.
   • Decontaminate the pipeline by inert gases again.
   • Cut or weld the pipeline.
3. The refrigerant should be returned to the appropriate storage tank. The system should be blown with oxygen free nitrogen to ensure safety. This process may need to be repeated for several times. This operation shall not be carried out using compressed air or oxygen.
4. Through blowing process, the system is charged into the anaerobic nitrogen to reach the working pressure under the vacuum state, then the oxygen free nitrogen is emitted to the atmosphere, and in the end, vacuumize the system. Repeat this process until all refrigerants in the system is cleared. After the final charging of the anaerobic nitrogen, discharge the gas into the atmosphere pressure, and then the system can be welded. This operation is necessary for welding the pipeline.

Procedures of Charging Refrigerants

As a supplement to the general procedure, the following requirements need to be added:

• Make sure that there is no contamination among different refrigerants when using a refrigerant charging device.
  The pipeline for charging refrigerants should be as short as possible to reduce the residual of refrigerants in it.

• Storage tanks should remain vertically up.

• ake sure the grounding solutions are already taken before the refrigeration system is charged with refrigerants.

• After finishing the charging (or when it is not yet finished), label the mark on the system.

• Be careful not to overcharge refrigerants.

Scrap and Recovery

Scrap

Before this procedure, the technical personnel shall be thoroughly familiar with the equipment and all its features, and make a recommended practice for refrigerant safe recovery. For recycling the refrigerant, shall analyze the refrigerant and oil samples before operation. Ensure the required power before the test.

1. Be familiar with the equipment and operation.
2. Disconnect power supply.
3. Before carrying out this process, you have to make sure:
   • If necessary, mechanical equipment operation should facilitate the operation of the refrigerant tank.
   • All personal protective equipment is effective and can be used correctly.
   • The whole recovery process should be carried out under the guidance of qualified personnel.
   • The recovering of equipment and storage tank should comply with the relevant national standards.
4. lf possible, the refrigerating system should be vacuumized.
5. If the vacuum state can’t be reached, you should extract the refrigerant in each part of the system from many places.
6. Before the start of the recovery, you should ensure that the capacity of the storage tank is sufficient.
7. Start and operate the recovery equipment according to the manufacturer’s instructions.
8. Don’t fill the tank to its full capacity (the liquid injection volume does not exceed 80% of the tank volume).
9. Even the duration is short, it must not exceed the maximum working pressure of the tank.
10. After the completion of the tank filling and the end of the operation process, you should make sure that the tanks and equipment should be removed quickly and all closing valves in the equipment are closed.
11. The recovered refrigerants are not allowed to be injected into another system before being purified and tested.

Note: The identification should be made after the appliance is scrapped and refrigerants are evacuated. The identification should contain the date and endorsement. Make sure the identification on the appliance can reflect the flammable refrigerants contained in this appliance.

Recovery

1. The clearance of refrigerants in the system is required when repairing or scrapping the appliance. It is recommended to completely remove the refrigerant.
2. Only a special refrigerant tank can be used when loading the refrigerant into the storage tank. Make sure the capacity of the tank is appropriate to the refrigerant injection quantity in the entire system. All tanks intended to be used for the recovery of refrigerants should have a refrigerant identification (i.e. refrigerant recovery tank). Storage tanks should be equipped with pressure relief valves and globe valves and they should be in a good condition. If possible, empty tanks should be evacuated and maintained at room temperature before use.
3. The recovery equipment should be kept in a good working condition and equipped with equipment operating instructions for easy access. The equipment should be suitable for the recovery of R32 refrigerants. Besides, there should be a qualified weighting apparatus which can be normally used. The hose should be linked with detachable connection joint of zero leakage rate and be kept in a good condition. Before using the recovery equipment, check if it is in a good condition and if it gets perfect maintenance. Check if II electrical components are sealed to prevent the leakage of the refrigerant and the fire caused by it. If you have any question, please consult the manufacturer.
4. The recovered refrigerant shall be loaded in the appropriate storage tanks, attached with a transporting instruction, and returned to the refrigerant manufacturer. Don’t mix refrigerant in recovery equipment, especially a storage tank.
5. The space loading R32 refrigeration can’t be enclosed in the process of transportation. Take anti electrostatic measures if necessary in transportation. In the process of transport, loading and unloading, necessary protective measures must be taken to protect the air conditioner to ensure that the air conditioner is not damaged.
6.  When removing the compressor or clearing the compressor oil, make sure the compressor is pumped to an appropriate level to ensure that there is no residual R32 refrigerants in the lubricating oil. The vacuum pumping should be carried out before the compressor is returned to the supplier. Ensure the safety when discharging oil from the system.
