Usage:

Flushing Filters :When using pure water machine for the first time ,filter should be flushed as following step :

Open the inlet water ball valve ,open RO bypass flush valve ,insert the plug of power supply in the socket of

power ,booster pump starts work ,concentrate emission port begins to emission concentrate water .After flushing

 process is complete ,open diverter valve in pressure tank ,close RO membrane flushing ball and now begin to

produce pure water ,at the same time concentrate emission flux dropped obviously.

Maintenance :

Third stage filter(RO Membrane ) :***0 months

Fourth stage filter : ****4 months

Cartridge replacement period depends on the pure water consumption and the source water quality .If adopt

safety replacement frequency mentioned above, the pure water quality can be guaranteed .Therefore above

suggestions are for reference only .

RO membrane flush :During the source of pure water producing ,RO membrane surface will be begrimed with
