Temperature Conditions
In the following temperature range, the air conditioning protective equipment will run and the air conditioner will stop. As a result, to ensure the normal operation of air conditioner, the following temperature conditions should be avoided.
| * Heating | Outdoor temperature -5-24°C Refrigerating Outdoor | temperature 21-43°C |
| Room temperature 20-27°C |
If the power is not cut off, and the machine is started immediately after stoppage or the mode is changed during operation, the protective device in the unit will work. The air condition compressor has to wait for 3 minutes to start running.

Features in Heating Operation (for cooling and heating equipment)
Pre-heating:
After heating is started, the indoor unit will be preheated for 2 to 5 minutes. After pre-heating process, the warm air comes out. When the room temperature is low, the electric heating will be activated, (for the cooling and heating equipment with auxiliary heater)
Defrosting:
During heating process, if the outdoor unit is frosted, the air conditioner will perform auto defrosting to enhance the heating effect. During defrosting, the fans of both indoor and outdoor unit will stop. After defrosting is finished, the heating process is recovered.

Inspection before operation
| Newly installed air conditioner | 1. Check if the installation is reasonable; 2. Check if the batteries are installed in the remote controller; 3. Check if the power supply is connected. |

1. Remove the filter screen
Make sure the air conditioner is turned off.
Gently push up the panel for small distance and turn over outward for a certain angle to open the panel. Lift up the filter screen and pull out toward yourself to remove.
2. Clean the filter screen
Gently pat it or clean with vacuum cleaner. If the filter screen is too dirty, it can be washed by the solution containing small amount of neutral detergent. After washing, dry the filter screen and install it to the original location.
Note: The filter screen should not be exposed to sunlight, dried by stove fire, or washed with hot water above 40^ C. Otherwise it will be deformed.
3. Clean the air conditioner
For safety purpose, the power plug must be unplugged before cleaning to avoid electric shock.
Do not wash the air conditioner with water Wipe the machine with soft cloth.
Do not wash the machine with volatile oil, gasoline, diluent, putty powder, etc.
For fingerprint or oil contamination, please wash with household neutral detergent.
4. Before the using season
Check if the air inlet and air outlet of indoor unit and outdoor unit are blocked.
The protective cover of outdoor unit must be removed.
Check if the installation base is corrosive or rusted.
Check if the power cable and grounding wire are in normal condition.
Check if the drain hose is bent, end is lifted, or is blocked.
Before operation, check and make sure the air filter screen is well installed. If the machine is running without air filter screen, the air conditioner may be damaged by dust and foreign substances.
5. After using season
Shut down the air conditioner and pull out the power plug.
Note: For common air conditioner, it will consume 5W power during standby status if the power plug is not pulled out. The standby power consumption of the machine marked with * is only 1W. 1W standby power consumption is measured in accordance with the enterprise standard Q/ZG 119 'Measuring Method of Standby Power Consumption for Household Air Conditioner".
Please carefully clean and maintain the air filter screen and other parts.
Cover the outdoor unit with plastic cloth to prevent the dust or waste from entering into the machine.

The following examples are not faults.
| After shutting down, the air conditioner cannot restart immediately. | If the user restarts the air conditioner when it is just stopped, the 3-minute protective tinner of air conditioner will be automatically activated and the air will the restarted 3 minutes later. |
| If the air conditioner is shut down when it is in refrigerating mode, the wind supply should not be turned off immediately and wind deflector should not be closed immediately, (for machine type marked with *) | It is because that the air conditioner is executing the mould-proof operation and the indoor unit is running with low wind and wind deflector will be closed after 30 seconds. |
| No wind is supplied in the beginning of heating | Before the heat exchanger of indoor unit is warm, stop wind supply to avoid blowing cold wind (for 2 to 5 minutes). |
| There is strange smell coming out when start-up. | It is because that the smoke and smell from cosmetics, wall or furniture is attached on the air conditioner and is dissipated by wind blowing. |
| Water flow sound can be heard during operation of the air conditioner | It is the flowing sound of internal refrigerant of the air conditioner |
| Crackle can be heard after starting or stopping the heating or refrigerating | It is caused by the thermal expansion and extraction. |
Before contacting the service department, please check the following items, which may save your time and expense.
| “Malfunction” | Analysis on the “Malfunction” |
| Air conditioner is unable to run. 1 | Check if power is failed.2 Check if power is connected.3 Check if Timing ON/OFF function is set.4 Check if the voltage is too high or too low.5 Check if the residual current circuit breaker is switched off. |
| Cooling (heating) effect is not good. | 1 Check if the set temperature is OK.2 Check if the air inlet and outlet of indoor and outdoor unit are blocked.3 Check if the air filter screen is blocked by too much dirt.4 Check if all the doors and windows are closed.5 Check if there are any heat resources. |
| Remote control is not functional | 1 When the remote control is exposed to direct sunlight or strong light, the remote signal may not be received. In this case, please bock out the sunlight or dim the lighting.2 Check if it is within the reception range and if any obstacles.3 Check if the battery voltage is sufficient. Or you should replace with new batteries.4 If the remote control display is not clear, please replace with new batteries. |
In case of following situations, please stop operation immediately, shut off power, and contact our dealers or authorized service center.
