Control Valve Functions
The control valve on the sand filter pump allows for different operational modes:
| Control Valve Position | 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. |
| Closed | Closed water flow between the filter and the pool | / |
Troubleshooting
Refer to the following table to diagnose and resolve common issues:
| Problems | Checking | Solutions |
|---|---|---|
| The motor cannot be started normally | Power plug not properly inserted Leakage protection disconnected Motor overheated or overloaded Causes motor to stop | Ensure 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 or upper cover | The seal ring of the body is lost or too dirty The control valve retainer is not tightly secured or damaged | Remove the upper cover of the control valve and sleeve 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 0.45-0.85mm. Or replace the sand. |
Long-term storage and storage in winter
Using the product in a frozen pool may damage the product and invalidate the quality warranty. If the product has to be used with antifreeze, propylene glycol may also be used. Propylene glycol is a non-toxic chemical unharmful to any plastic parts. Other types of antifreeze are highly toxic and may be harmful to the product's plastic elements.
- Before discharging the water or repositioning of the pool, make sure the discharge direction is towards the discharging ditch and away from the home. Review local regulations for special water treatment requirements.
- Switch off the product and remove the power plug.
- After emptying, remove all connected sand filter pumps, corrugated tubes and filter hoods on the pool wall.
- Unscrew the drain valve (8) in an anticlockwise direction to completely empty water inside the body. The drain plug is at the bottom of the body.
- Dry the parts of the sand filter pump and corrugated tubes.
- Lubricate the seal rings and washers in the order below for long-term storage.
- The best practice for product storage is to dry the parts and motor and replace them in the original package. To avoid shrinkage or corrosion, do not cover or wrap the motor with a plastic bag.
- Please store the motor and parts in a dry place at 0°C (32°F) ~ 40°C (104°F).
