2, quartz sand, activated carbon, softening resin and other filter materials.
3. Waterway connection: the water inlet of the raw water pump is connected to the water source, the outlet of the pre-filter is connected to the inlet of the main engine, and the pre-processor and the outlet of the main engine are connected to the sewer through pipelines.
4. Circuit: First, ground the grounding wire reliably, and connect the supplied power cord to the room electric control box.
5. Connect the water source and power supply, and operate step by step according to the requirements of "Pretreatment Operation Instruction", and the pretreatment debugging operation is completed.
6, using this machine, the original water pump switch, dial to the automatic position, and unscrew the stop switch. Connect the water source and power supply, and when the outlet pressure 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 to 1.0- 1.2Mpa. When it is started for the first time, the RO membrane system should be manually flushed for 30 minutes.
