Control Valve Warning
To prevent equipment damage, please unplug before changing the Control Valve function. Sudden changes in valve position while the pump is running may damage the equipment, resulting in personal injury or property damage.
Control Valve Usage:
Press down on the Control Valve handle and rotate to specified function.
Note:
During the operation of the sand filter pump, check the pressure reading of the manometer. Generally, when recommended pressure of the sand filter pump is less than 0.2bar (3psi) (green area), it runs normally. Note: You must make sure that maintenance begins only after the sand filter pump is unplugged. Otherwise serious risks such as personal injury and even death may occur. Note: Record the reading of the manometer during the operation of the sand filter pump. When the manometer shows a pressure of 0.2bar (3psi) or higher, please clean up the sand bend or replace the sand. Use "backwash" and "rinse" functions. Note: regular rinsing according to use situation is recommended.
Manometer Reading: The green area indicates normal operation up to 0.2 bar (3 psi). Pressures above this may require cleaning or replacing the sand.

Diagnosis of Problems and Solutions
| Problems | Checking | Solutions |
|---|---|---|
| The motor can not be started normally | Power plug not properly inserted Leakage protection disconnected Motor overheated or overloaded Causes motor to stop | Make sure the power cord is inserted into the 3-core grounded metal receptacle. Reset circuit breaker. If the problem persists, the power system may be defective. Power off immediately and confer with an expert. Allow the motor to cool naturally and start it again. |
| Filter Unable to rinse the pool | No sand in the body Location error of the control valve Excessive dirt in water Filter barrel blocked | Sand filling Refer to sand filling instructions The control valve rotates to the filter position to prolong the running time Clean the filter barrel |
| The filter is unable to discharge water or the water flow rate is too slow | There is blockage at the inlet There is an air leakage at the gap of the inlet Excessive dirt in water Filter medium is blocked by impurities The pool is connected with a cleaning device | Check and clear away the blockage in the water pipes Tighten the nozzle nuts and check the damaged point of the nozzle and water height Clean the filter screen Backwash Disassemble the cleaning device connected to the pool |
| Filter fails to run | Water level is too low Filter screen is blocked Air leakage from the inlet pipe Motor or blade is blocked | Inject water to adjust water level Clean the filter screen in the pool Tighten the nozzle and check the damaged point Replace the fittings |
| Water leakage on the control valve and upper cover | The seal ring of the body is lost or too dirty The control valve retainer body is not tightly secured or damaged | Remove the upper cover of the control valve and the seal ring of the body Clean the seal ring of the body with a water pipe Tighten the screw with a screwdriver Replace the fittings |
| The manometer fails to run | The inner wall of the manometer is blocked The manometer is damaged | Remove the manometer from the control valve and clear away the impurities on the inner wall Replace the fittings |
| Sand enters the pool | The sand particles are too fine | Use 20# quartz sand only Particle size of the sand is 0.45-0.85 mm Or replace the sand |
Control Valve Functions
| Location of control valve | Functions | Water flow direction |
|---|---|---|
| Filter | Normal filtering to rinse the pool | Water flows through the filter bed where the sand filter pump lies and then enters the pool |
| Backwash | Reverse-direction water flow to rinse the filter bed | Water flows through the filter bed where the sand filter pump lies and is then directly discharged from the drain outlet. |
| Rinse | This function is used for first startup. Sand in the sand tank is rinsed and the sand bed after backwashing is leveled. | Water flows through the filter bed where the sand filter pump lies and is then directly discharged from the drain outlet. |
| Drain | Discharged directly from the drain outlet, used to lower water level or discharge water from the pool | Discharged directly from the drain outlet of the sand filter pump without passing through the filter bed |
| Recirculation | Circulates pool water without passing through the filter bed. | Water flows directly into the pool through the control valve of the sand filter pump without passing through the filter bed |
