Iii. Operating Instructions for the Preprocessor

1Operating Instructions for multi-media filter:

APlace the multi-media filter in an appropriate location, remove the manual multi-way filter valve at the top of the filter, fill coarse and fine quartz sand in the order from bottom to top, and then tighten the multi-way valve at the top.

BConnect the water source and power supply.

CRefer to the arrow and text diagram of the multi-way valve to backwash and forward wash the filter material in the multi-media filter until the effluent from the filter is clear. Then, turn the multi-way valve to the working position.

DThe quartz sand is packaged naked to ensure the filtration effect. (Note: It should not be bagged

2Operating Instructions for Activated carbon adsorption filter:

APlace the activated carbon adsorption filter in a suitable location. Remove the manual multi-way filter valve at the top of the filter. Fill the bottom with coarse quartz sand in the order from bottom to top, then fill the activated carbon and tighten the multi-way valve at the top.

BConnect the water source and power supply.

CRefer to the arrow and text diagram of the multi-way valve to backwash and forward wash the filter material inside the activated carbon adsorption filter until the effluent from the filter is clear. Then, turn the multi-way valve to the working position.

DThe activated carbon is packaged naked to ensure the filtration effect. (Note: It should not be bagged

3Operating Instructions for resin softening filter:

APlace the resin softening filter in a suitable location, remove the manual multi-way softening valve at the top of the filter, fill it with cationic softening resin, and tighten the multi-way valve at the top.

BConnect the water source and power supply.

CInlet water softening filtration operation: Refer to the arrow and text diagram of the multi-way valve to backwash and forward wash the filter material inside the resin softening filter until the effluent from the filter is clear. Then, turn the multi-way valve to the working position. Note: When starting to take in water, the water inlet valve should be opened first1/3After water comes out of the drain of the water softener, slowly open the inlet valve.

DResin regeneration operation steps  Just follow the sequence of backwashing, salt drawing, water addition, forward washing and operation. Note that there should always be salt but no water in the salt tank, that is, the salt solution is in a saturated state. Note: When performing the flushing and regeneration work on the pretreatment, please turn the raw water pump switch to the manual position. During normal operation, please turn the raw water pump switch to the automatic position. Only in this way can the equipment work normally.

Iv. Operation Steps for Equipment Installation and Commissioning:

1Place the main unit and preprocessor near the water source and power supply.

2It is filled with filter materials such as quartz sand, activated carbon and softening resin.

3Connect the waterways: Connect the inlet of the raw water pump to the water source, connect the outlet of the pre-filter to the inlet of the main unit, and connect the drainage outlets of the pre-treatment unit and the main unit to the sewer with pipelines.

4Circuit: First, ensure the grounding wire is reliably grounded, and then connect the power cord provided randomly to the electrical control box in the room.

5Connect the water source and power supply, and follow the steps as required in the "Pretreatment Operation Instructions" to complete the pretreatment debugging operation.

6To use this machine, set the switch of the raw water pump to the automatic position and unscrew the stop switch. Connect the water source and power supply. When the pressure at the outlet of the multistage pump reaches the set value of the pressure controller, the multistage pump starts to work. After the multistage pump is started, adjust the system pressure to1.0-1.2Mpa. Initiate responseROThe membrane system is manually flushed30Minutes.

Installation precautions for the entire machine

1The installation site of the equipment should be flat, clean and tidy, and close to power and water sources.

2Do not approach fire sources or any heating elements.

3In northern regions, equipment must not be installed outdoors to prevent internal freezing, which could damage the instruments and filter elements.

4The installation location of the equipment should facilitate drainage and keep the drainage pipe of the equipment unobstructed.

(1When the water source pressure＜0.12Mpa. "Traffic"＜5.0T/HDuring the operation of this machine, the multistage pump will repeatedly start---Stop---The phenomenon of startup. At this point, the machine should be stopped from use to prevent the motor from burning out. In areas with insufficient water pressure and flow, please add a raw water tank in front of this equipment.

(2The working pressure of the water pump used in the system is ensured to be within1.0-1.2MpaMake sure the water pump operates within its rated head range.

Five: Water production operation

1Switch the raw water pump switch on the operation panel to the automatic position, turn on the stop switch, connect the water source, and close the power supply. When the water pressure reaches the set value of the pressure controller, the equipment will start working automatically.

2After the entire machine has entered the working state, adjust the system pressure1.0-1.3Mpa.

3If it is difficult to start the multistage pump, slightly close the outlet pressure reducing regulating valve (but do not fully close it; a certain flow rate should be reserved). After the multistage pump starts, unscrew it.

4If the inlet water pressure is too low or the flow rate is insufficient, please use a raw water tank or build a water storage pool for the equipment to operate normally.

Six: Precautions during Operation

1The water output of this machine depends on the water temperature25℃At that time2000L/HAs mentioned above, the water temperature rises or drops1℃The water production will increase or decrease accordingly3％Left and right, this isROIt is determined by the characteristics of the membrane.

2EnterROThe residual chlorine content in the water of the membrane should be strictly controlled0.1PPmThe method is as follows: Connect water to the sampling port of the adsorption filter and test it with a residual chlorine detector. If the standard is exceeded, the activated carbon filter material should be replaced.3When the water inflow is insufficient or the pressure is too low, the water shortage and under-pressure system of this machine will automatically shut down the equipment.

4When this machine is used for the first time, due to the presence of preservatives in the membrane. The conductivity of the effluent will be relatively high. Rinse1-2If water is produced normally for a period of time, the conductivity of the effluent water will decrease significantly.

Note

1If you choose itAC380VFor the motor with voltage, it is essential to ensure that the rotation direction of the motor is consistent with the rotation direction marked on the pump; otherwise, the water pump may be damaged.

2When the water source is short of water or the pressure is too low, this machine will automatically shut down. It will automatically restart when the water source pressure is restored.

3Automatic flushing: Executed upon startup of the equipment90STime flushing is completed, and it automatically switches to water production work. Each time the machine is turned on or the water is full during operation, it should be flushed10S; Continuous operation3hOr wait until the water is full3hAutomatic intervention for flushing10S. When flushing the membrane, the system pressure drops. Please do not adjust the regulating valve.4When operating normally for water production, the pressure of the membrane system should be at1.0-1.3MpaBetween them (adjusted through the regulating valve).
