Precautions in operation

1. The water production of this machine is the water production when the water temperature is 25 °C. When the water temperature rises or drops by 1 °C, the water production will increase or decrease by about 3%, which is determined by the characteristics of RO membrane.
2. The water entering the RO membrane should be strictly controlled to have a residual chlorine content of 0.1 ppm or less. The method is: the adsorption filter is connected to the water at the sampling port, and the residual chlorine reagent is used for testing. If the standard exceeds the standard, the activated carbon filter material should be
3. If the water intake is insufficient or the pressure is too low, the machine lacks water and under pressure system to automatically stop the
4. When the machine is used for the first time, it is due to the preservative contained in the film. The conductivity of the effluent will be too high. After 1-2 hours of washing and normal water production for a period of time, the conductivity of the effluent will be significantly

Note:

1. If you choose a motor with AC380V voltage, be sure to note that the direction of rotation of the motor is the same as the direction of rotation of the pump. Otherwise, the pump will be damaged.
2. When the water source is short of water or the pressure is too low, the machine will automatically stop and restore the water source pressure to start

   • When the residual chlorine content exceeds 0.1PPm, the activated carbon filter material should be
2. Replace the fine filter in the security filter
   • The filter is equipped with a 5um fine filter to effectively block activated carbon particles to ensure the safety of the RO membrane and pump. When it is blocked, it should be
   • When replacing, unscrew the top cover of the security filter, remove the old filter element, and replace the new filter element and then tighten the

RO membrane drug cleaning method

when is the need for drug cleaning?

• After using this machine for a period of time, due to the contamination of the RO membrane surface by the hardness ions, bacteria, organic colloids and other substances in the water plus  the concentration polarization phenomenon unique to the RO membrane itself, the RO membrane surface scale pollution will cause the water volume to drop or The salt rejection rate is lower than the rated value. When the normal working performance of the RO membrane cannot be restored by the daily physical washing method, the RO membrane needs to be chemically cleaned.

Drug cleaning methods:

1. Prepare a 60L plastic clean container, connect the booster pump inlet to the main unit drain with 2 hoses, and place the other end of the hose in the container (below).
2. Put 50L of pure water in the container, pour 1 bag of RO membrane cleaning agent, and mix well.
3. When the original water switch is set in the manual position, the host will automatically start the drug cleaning on the first membrane, and turn off the power after 1
4. After the shutdown, restore the pipeline according to the normal working
5. Rinse the RO membrane system for 30

Precautions:

Contaminant removal on the RO membrane can be achieved by chemical and physical cleaning, and sometimes by changing operating conditions. As a general rule, cleaning should be performed when one of the following conditions occurs.

1. The pure water production under normal pressure drops to 10%-15% of the normal
2. In order to maintain normal product water flow, the temperature-corrected feed water pressure is increased by 10%-15%.
3. The water quality of the product is reduced by 10%-15%, and the salt permeability is increased by 10%-15%.
4. the use of pressure increased by 10% -15%.
5. The pressure difference between the various sections of the RO increases significa
