1. General plating solution was filtered, because the plating solution containing traces of organic matter, easily contaminated liquid, powdered active carbon powder must be used within the syrup to absorb organic matter is customary to keep the cleaning solution. 2. General operator cleaning filter, not the impurities within the cartridge is completely clean, easily small amount of residual impurities, started when the filter cartridge is easy with the residual impurities in the liquid flowing into the tank, to prevent man-made negligence in operation, specially designed with a circulation loop to provide ease of operation, 3. Instructions: (A) Please install the plastic in the filter at the outlet and where, (B) before use to open the exhaust valve (III). Close the outlet where the power switch and then start the motor starts running, the gas and the liquid discharged through the dosing tank. (Iv) Open the recirculation valve, and then open the dosing valve, so that liquid in the dosing tank to produce a fixed level after adding filter aid powder, loop 3 minutes before adding the active carbon is recycled three minutes, then discharged liquid Likewise there is no active carbon powder can be discharged, (V) using the detection port valve, direct sampling check the cleanliness of the liquid and filter effects, (Vi) Where then open the outlet, tightly closed circulating valve, an exhaust valve and then shut tight, look after dosing tank liquid remaining a little longer dosing valve shut tight, complete dosing process of making normal filter filter
