Quartz sand filter operating instructions

Quartz sand filter operating instructions: 1. Backwashing: turn on valves 2 and 4 in turn and close the rest, then turn the working mode switch on the control panel to manual, then turn on the backwash pump switch to start the backwash pump, backwash for 10-15 minute. The water recoils the medium from bottom to top, so that the sediment deposited during the working process is discharged from the positive and recoil outlet. 2. Positive washing: Open valves 1 and 3 in sequence, and then close valves 4, 2, and 5 in sequence. The water will flush the medium from top to bottom for 10-15 minutes, so that the sediment can be discharged from the positive and reverse flushing outlet.

3. Filtration working status: open valves 3 and 5 in sequence and close the rest, then turn on the filter pump, the system works, and the water is filtered through the medium from top to bottom. 4. Quartz sand must be backwashed after being used for a period of time, usually once every 1-2 days, and if the raw water is poor, it needs to be backwashed once or twice a day. Installation precautions: 1. The reserved pipe interface of the reaction tank water distributor is a socket interface. Therefore, for the convenience of maintenance in the future, it is best to install the union first, and then connect the elbow or tee; 2. The material of the water distributor is ABS material, therefore, when using the socket connection method to connect the union, pay attention to the matching of the material and the glue; 3. When feeding (filling quartz sand), pay attention to filling the quartz sand with a specification of 2-4mm first, Install 1-2mm quartz sand afterward, and the total height can be controlled at about 1m. At the same time, it should be noted that a small amount of material should be fed evenly at the beginning to prevent the quartz sand particles from wearing out the lower water distributor; 4. All installations are completed. Finally, it is necessary to check the sealing condition of each part of the upper and lower interfaces, and the flange screws need to be adjusted according to the diagonal principle; Poolking is the best swimming pool equipment manufacturer and supplier in China.
