/PRZWT/SHANDONG, June 26, 2024 - As June enters, high temperatures across the country are hitting strongly. Halfway through June, some areas in Hebei, Shandong, Henan and other regions have issued orange warnings for high temperatures, according to China Weather Network. The first 40 degrees Celsius this year has been "mentioned", breaking the record for the highest temperature in June. At the same time, most of southern China, including southern China and Jiangnan, have continued to rain, entering the middle period of rainfall concentration, and the "muggy and unbearable" plum rainy season has begun.
As the temperature rises, air conditioners are about to enter the peak period of use, but central air conditioners that have been idle for a spring are likely to encounter troubles such as "not turning on", "unsatisfactory cooling effect", and "peculiar smell after turning on". In order not to affect the use of subsequent high-temperature days, Daikin officials remind the following precautions.
Boot if you encounter startup difficulties or U4 code? Daikin official advice
① What should I do if the air conditioner cannot be turned on?
During the season change, due to the long-term non-use of the central air conditioner, many users will take power-off treatment and turn off the "air switch". If the central air conditioner is used again, it is recommended to power on the power 6 hours in advance to preheat and "wake up" all parts to avoid possible start-up difficulties due to long-term non-operation. At the same time, by preheating, ensure that the lubricating oil in the compressor is separated from the refrigerant, effectively avoid accidental damage to the compressor and prolong the service life.
What should I do if the wire controller displays the U4 code?
The U4 code is caused by communication problems between indoor and outdoor units. You can try to cut off the air conditioner power supply and wait for 10 to 15 minutes, and then power on to restart; if it still cannot be solved, please contact the official after-sales service of Daikin.
Can't cut the refrigeration after booting or the refrigeration is not ideal? Daikin official suggestion
① What should I do if the wire controller shows [no hot and cold options]?
[No hot or cold option] means that the wire controller in the current room cannot switch the cooling mode. If this happens, turn off each wire controller one by one and wait a few minutes to restart; if you use the [Gold Air App], you don't need to run from room to room. You can turn off all air conditioners with one click through the Gold Air App, and then start one at will and adjust it to the cooling mode.
② How to adjust the trend, the cooling effect will be better?
Winter heating, usually adjust the trend louver to blow upward. When the central air conditioner is turned on in summer, Daikin officially recommends adjusting the trend to parallel direct blowing, then setting the temperature slightly higher, and turning on large air volume. After the indoor temperature is suitable, re-adjust the temperature and air volume according to personal comfort, so that not only has a comfortable cooling effect, but also avoids the trend condensation phenomenon caused by the excessive difference between the air outlet temperature and the indoor temperature.
Does the air conditioner smell bad after turning it on? Daikin official suggestion
Regarding the odor of the air conditioner, it may be the odor caused by the dirty filter screen caused by the long-term uncleaning of the indoor unit, or the residual water in the internal unit has not been cleaned for a long time, or it may be the odor caused by the adsorption of various odors in the air onto the heat exchanger. Therefore, before the air conditioner is used every year, Daikin recommends a cleaning and maintenance of the air conditioner.
In response to the situation that the filter screen is too dirty, you can try to clean it yourself. If you can't grasp the usage of the filter screen, you can check it at any time through the [Gold Air APP]. Once the filter screen expires, the Daikin Central Air System Daikin Care air housekeeper will take the initiative to pop up a window reminder, which can make an official appointment for cleaning with one click, and it is more secure to use!
For relatively professional operations such as cleaning hot fin and drain pipes, Daikin officials recommend booking a professional cleaning team. Daikin after-sales engineers provide three cleaning methods: "dry ice cleaning", "steam cleaning" and "deep cleaning" through professional training and professional tools, and provide a full range of cleaning and sterilization services.
