The specific operation sequence of various functions of the swimming pool filter sand tank

The specific operation sequence of various functions of the swimming pool filter sand tank 1.1 Filter function check before starting the machine. Before starting the machine, the multi-way valve of the filter sand tank should be adjusted to the filtering state; Whether the collector is blocked, if so, clean it first; check whether there is air in it, and if so, drain the air first; Tighten it to make it tight and airtight; Check whether the drug solution pipe of each drug delivery system is normal and unblocked, whether there is still drug solution in the drug barrel, and whether the valve on the nozzle of the drug injector has been opened to ensure that the drug delivery system is in a ready state; Check Whether there is air accumulated in the main return water pipeline, if there is, it must be removed through the drain valve; Turn on one water pump motor first in the starting sequence; after the water pump motor is running normally, turn on the water pumps in sequence, and the backup pump does not need to be turned on; Check the records after starting Check the pressure gauge index on the filter to check whether backwashing is necessary; check the operation of the water pump to see if it runs smoothly without noise; check whether the dosing systems are operating normally; go to the swimming pool to visually check whether the water outlets of each water injection port are normal. 1.2 Check the backwash function before starting up. If the reading of the pressure gauge on the filter sand tank is higher than 2.5kg/cm2 or above, you need to backwash the filter sand tank immediately; confirm that the relevant water pumps that need to backwash the sand tank have stopped running; Adjust the multi-way valve on the filter sand cylinder to the backwashing state; confirm that the relevant valves on the pipeline are in the correct position. Backwash sequence First run the water pump; check and observe the clear water mirror on the sand tank until the water is clean; then turn off the water pump.

Note: If it is impossible to check the backwash water, the duration of each backwash is preferably 2-3 minutes. 1.3 Before starting the rinse function, check to confirm that the backwash has been completed; confirm that the water pump is turned off; adjust the multi-way valve on the filter sand tank to the rinse state; confirm that the relevant valves on the pipeline are in the correct position; rinse order: first turn on the water pump; Turn off the water pump after looking at the clear water mirror for 1 to 2 minutes (take the clear water as the criterion). 1.4 Check the drainage function before starting the machine. Adjust the multi-way valve on the sand tank to the drainage state; make sure that the relevant valves on the pipeline are in the correct state; check whether the hair collector is blocked, and if so, clean it first; Air, if there is air, must be drained; Check whether the tank cover is tight and airtight, if there is air leakage, the tank cover must be tightened to make it airtight; Check whether there is air accumulated in the main return pipe, if so, then It must be drained through the exhaust valve; If there is an overflow return pipe, please close the main valve on the overflow return pipe; Note: During the drainage process, please try to prevent the interruption of the water pump; 1.5 Check before starting the cycle function Before starting the machine, adjust the multi-way valve of the filter sand tank to the circulation state; make sure that the relevant valves on the pipeline are in the correct state; check whether the hair collector is blocked, and if so, clean it first; If there is air, the air must be discharged; Check whether the tank cover is tight and air-tight, if there is air leakage, the tank cover must be tightened to make it air-tight; If there is an overflow return pipe, please close the overflow return pipe Check whether other equipment is in good condition; Check after starting up: whether the water pump is running normally; whether other related equipment is running normally.

1.6 Shutdown function Turn off the water pump, shut off all the water flowing to the sand tank or swimming pool (close the sand tank), and adjust the multi-way valve of the filter sand tank to the closed state.
