Maintenance:

1, maintenance before startup

Usually, household air conditioners are turned off in September, turned on in May and June of the following year, and stopped for more than half a year. Therefore, a comprehensive "diagnosis" must be carried out before starting the air conditioner to check whether there is a "fault" in the air conditioner.

According to the inventory results, under the guidance of professional and technical personnel, do a good job of maintenance and cleaning, including the casing, fuselage and filter screen of outdoor and indoor units, and then start trial operation to observe the cooling speed and effect.

2. Maintenance during startup

After the air conditioner is turned on, it is necessary to determine the maintenance frequency during the start-up of the air conditioner according to various factors such as environmental conditions, climate conditions, start-up time, surrounding dust, air cleanliness, indoor cleanliness and so on. Poor environmental conditions, hot weather, outdated air conditioning, long start-up time of air conditioning, and increased maintenance times during air conditioning start-up, generally once a month and a half.

If the environmental conditions are good, the air conditioner is relatively new, there is less dust in the air, and the air conditioner can be turned on reasonably and can be used alternately with the electric fan, then the maintenance cycle can be extended appropriately, from air conditioner on to air conditioner off 1-2 times. Maintenance should be careful and meticulous, leaving no dead ends. Reach the standard, improve the cooling speed and effect, and achieve energy saving, freshness and comfort.

3. Maintenance after downtime

It is a perennial law to turn on the air conditioner when the weather gets warmer and turn off the air conditioner when the weather gets cooler. Pay attention to the comprehensive and detailed inspection of outdoor units and indoor units before the air conditioner is turned off. Maintenance, maintenance and cleaning should be linked one by one, and cannot be separated. Leaked links should be fixed and strictly checked.
