I. Overview

　　This machine adopts single-stage low-pressure reverse osmosis technology to purify tap water. Combined with a carefully designed filtration and adsorption system, it can effectively remove various substances in water that are harmful to health, such as residues and heavy metal ions, and can also remove carcinogenic and pathogenic substances like fluorine that cannot be removed by conventional methods. The conductivity of tap water in the vast majority of regions in China is≤500us/cmTherefore, when using this water machine, it is essential to pay attention to the quality of the raw water and strictly follow the instructions for operation, maintenance and upkeep. The conductivity of the purified water produced can be maintained within the national standard requirements10us/cmBelow, ensure that the pure water produced for direct drinking complies with the regulations issued by the Health Supervision Department1998"19Attachment of Document Number4Hygiene requirements and the Ministry of HealthGB5749-85"Hygienic Standard for Drinking Water"

　　This machine integrates the complete and standardized production process of drinking purified water into one. It features an open cabinet design and is easy to maintain and service. The reverse osmosis program controller is adopted to control the automatic operation of the system. The operation process and faults are displayed on the panel, making the operation simple. The switch system only requires one switch to complete, which greatly improves the stability of the system operation. It can serve as the core equipment for water purification houses in communities, industrial zones, oil fields, etc., and also as water treatment equipment for industries such as beverages, chemicals, hospitals, and electronics.

　　　Iv. Operation Steps for Equipment Installation and Commissioning:Two-stage reverse osmosis equipment

　　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"＜4.0T/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:Two-stage reverse osmosis equipment

　　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 OperationTwo-stage reverse osmosis equipment

　　1The water output of this machine depends on the water temperature25℃At that time1500L/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).

　　5The conductivity value displayed by the conductivity meter is for reference only.
