If the air conditioner in winter is not used for a long time, the filter should be cleaned to prevent dust accumulation from affecting the next use. If the filter has too much dirt, it can be washed with water or neutral detergent, but it should not be washed with hot water above 50 °C or strong alkali such as washing powder, gasoline, banana water or acidic liquid to avoid deformation.
When cleaning the panel, be careful not to use too much force. If the dirt is heavy, you can use a neutral detergent diluted with water. Unscrew the water from the cloth first, then wipe it. After cleaning, wipe the detergent on the cabinet thoroughly. Select the air conditioner function key in the “air supply state†and run for 3-4 hours to let the air conditioner air dry and keep the machine dry. Then turn off the air conditioner and unplug the power cord. Remove the battery from the Mitsubishi central air conditioner remote control to prevent the battery from leaking and corroding internal components.
Clean the outdoor radiator. Do not insert the stick object, otherwise the fan will be stuck or damaged. If the outdoor cabinet cannot be wiped with a cloth, use a lighter and cleaner mop to clean it. Carefully remove the panel, scrub with a soft rag, and gently brush the heat exchanger of the indoor unit with a small brush. Then cover the casing with a cover to prevent dust from accumulating and affecting the normal operation of the machine. However, please note that since the heat sink is a very thin aluminum material, it is easily deformed after being stressed, so be careful to brush it.
The weather is getting colder, many people want to use air conditioning to heat, then when re-enabling, pay special attention to remove the dust cover covered by the outdoor unit, check if there is too much dust on the heat sink, and whether there are any debris that affects the ventilation around. Whether the fan is stuck or not, and whether the power cord and the pipe insulation sleeve are bitten by the mouse. If the condenser and the evaporator have more dust attached to affect the exchange effect, try not to wash it with water at will. When entering the compressor, it is best to have a professional technician clean it. Since the indoor unit is not used for a long time, it is also necessary to clean the filter and the machine casing. The merchant also reminds the user to read the manual in detail before heating, to confirm that the remote control battery is fully charged, and whether the test machine is running normally. If the sound is abnormal, notify the professional technicians in time, and do not force the machine to run.
1. Maintenance before starting
Usually, household air conditioners are shut down and shut down in September, and will not be turned on until May to June of the following year. Therefore, before the air conditioner is turned on, you must do a comprehensive "diagnosis". Check whether the air conditioning equipment is "faulty". According to the results of the inventory, under the guidance of professional and technical personnel, do a good job of maintenance and cleaning. This maintenance and cleaning should be in place. The outer casing, the body, and the filter of the outdoor unit and the indoor unit are included, and then trial operation is started to observe the cooling speed and effect.
2. Maintenance during the boot process
After the Mitsubishi central air conditioner is turned on, depending on environmental conditions, climatic conditions, number of power-on hours, surrounding dust, cleanliness of the air, whether the room is clean, and other factors determine the number of maintenance during the air conditioner startup process. The environmental conditions are not good, the weather is hot, the air conditioner is old, the air conditioner is turned on for a long time, and the number of maintenance during the air conditioner startup is increased, usually one and a half months. If the environmental conditions are good, the air conditioner is relatively new, the air is less dusty, the air conditioner is turned on reasonably, and it is used alternately with the electric fan. The maintenance cycle can be extended appropriately, from the air conditioner to the air conditioner shutdown maintenance 1-2 times. Maintenance should be serious and careful, leaving no dead ends. Meet the standard, improve the cooling speed and cooling effect, and achieve energy saving, fresh and comfortable.
3. Maintenance after closing
The weather is getting warmer, the air conditioner is turned on, the weather is getting cold, and the air conditioner is turned off. This is a regular year. Note that the outdoor unit and the indoor unit should be thoroughly examined before the air conditioner is turned off. Maintenance, maintenance, cleaning must be a ring, can not be disconnected, easy to leak the link should be tightened, strict inspection, after completing the above steps, set the air conditioner hood to prevent dust pollution, prevent air conditioning drip and water, Keep clean and prepare for reuse in the coming year, so as to clean, save energy and extend the service life of air-conditioning equipment. For high-quality split machines of well-known brands, the cabinets should be protected and the energy-saving effect should be fully exerted.
4. Central cleaning should pay attention to
Disconnect the power and open the cover;
Removing the filter to expose the evaporator sheet;
Unplug the air conditioner cleaning agent inside the cover;
Shake up and down;
Spray the air conditioner cleaning agent evenly onto the evaporator, wait for 5 minutes, turn on the air conditioner for 5 minutes (cooling), and finish the cleaning work.
The above points are today's Mitsubishi central air conditioner http:// for everyone to solve the central air conditioning in the summer before the use of maintenance to do, in addition to remind everyone, the air conditioning industry has many years of practice has proved that the air conditioner cleans 2-3 per year The second best. Usually, the air conditioner is cleaned once before the air conditioner is turned on, and the air conditioner is cleaned once in the middle period, and the air conditioner is cleaned once when it is turned off. Sometimes when the air conditioner is turned off, after a large cleaning of maintenance, maintenance, cleaning, etc., the air conditioner is covered with a hood. It will be cleaned in the coming year, and the filter net will be clean. At this time, the cleaning before the air conditioner is turned off is one year. Cleaning twice, the effect is very good, saving labor and cost, reducing operating costs, and not affecting the cooling effect.
Hand-held roller working conditions:
1. The sub-layering of the cement stabilized layer in the highway municipal maintenance and refilling construction; the compaction of the asphalt concrete at the edge of the trench and at the corners.
2. When the structures such as pipe culverts, passages, and abutments are backfilled during road construction, the compaction work of the large Road Roller cannot be worked.
3, municipal garden landscape, real estate residential community landscape, pavement laying in the construction of golf course, pavement compaction of sidewalk
4. For other construction occasions where the construction area is narrow and sensitive to the weight of the compaction equipment, the compaction work can be completed flexibly and efficiently.
Walk-behind vibratory roller features:
Small size, compact structure, easy transportation, high working force and high efficiency. It can be used with large road rollers. Extra large water tanks reduce the hassle of replenishing water and make the equipment grow continuously for continuous working hours. The adjustable folding operating handle provides the operator with a comfortable operating environment that is easy to transport or collect after folding.
There is a self-clamping polyurethane automatic cleaning scraper on the wheel to prevent dirt and asphalt from accumulating on the steel wheel, making the compaction smoother.
Higher path edge clearance and smaller side clearance. Particularly suitable for compaction against walls and road rocks.
