Clean air filter method: 

1. On the surface of the air filter is not very dirty, the filter to get the outside with clean compressed air purge, purge to the dust, in the light with the eye. 

2. The filter surface is dirty, need to be washed. In general the water chamber (air conditioning) with trough and add about 100 jins of drinking water, will be 1 kg bottled after diluted detergent, to filter into the groove to all submerged in the water. Rinse several times, and dirt, and finally rinse until water cleaning, take out on stainless steel grille to drag over the dry water, then dry flat out on the shelf shade, dries to double when often turn to speed up the drying speed. 

3. Every day with dishcloth to air conditioning body outer surface and accessory pipeline, instrument thoroughly clean, make the equipment clean and bright. 

4. On the equipment of oil pollution, glue on the class with a dishcloth dip detergent wipe, reoccupy water wipe clean, a trace. 

5. At the beginning of each change after effectively filter, in effect, should put the air conditioning unit interior wall plate, fan, heater, cooler, diffuser plate, a thorough cleaning, wipe dust, dirt, grease, there shall not be blind Angle, and then in the early effect and effectively filter installation. 

6. Once every half moon internal cleaning of the system, use wet cloth to wipe, internal first thoroughly clean with dry dishcloth. 

7. Replace the high efficiency air filters, the filters should be installed to the four boxes and surrounding with a wet cloth to wipe clean, clean and repeated three times, wipe the hepa filter should immediately after installation. Hepa filter should be split open a case at the scene, and check after passing to install immediately, in order to prevent the dust fall into high efficiency filter. 

8. Detection of clean room number of suspended particles significantly overweight, high efficiency filter eventually fell to the early air volume of less than 70%. 

After 9. High efficiency filter replacement, dust particle counter for high efficiency filter and installation joint leakage. At the same time of scanning inspection, tighten bolts or silica gel plugging with epoxy resin. 

10. The hepa filter testing, replacement shall be recorded in a timely manner. 

After 11. High efficiency filter replacement, should perform leak test and verify. 

Clean the air filter to note: 

1. The filter cloth after cleaning, if the initial resistance value is lower than the first time this filter filter installation when using initial resistance value, shall not be used, should be replaced in a timely manner; Filter by 2 times even after cleaning the differential value is greater than the initial value will be replaced. 

2. Take efficient filter, pour the suitcase, the high efficiency filter poised to fall to the ground. 

3. After cleaning the filter should be examined for the damage, if any should be replaced in a timely manner, when cleaning, do not knead, also do not machine wash or dry. 

4. Early in the process of cleaning, effectively filter is prohibited in confusion, should have a number to distinguish. 

5. Each air purification system should spare a set of filters, so that when cleaning the timely replacement. 

Conclusion: remove the air filter, pay attention to light with light. Spray air freshener in the filter, and clean cloth graze filter shell. (note: the bag filter in the compressor dust blown clean can, generally blow after three times, will need to be replaced.)
