Direct assembly and launch pump-filter Bestway starts with the choice of a flat area, where the device will not suck dirt from the bottom, and the hoses will lie down without inflections. Before connecting to the power grid, make sure that multiport is placed in the "Filter" or "Backwash" mode, but is not in an intermediate position, which can damage the internal mechanisms. Right. pre-preparation The equipment eliminates most problems with water pressure and circulation during the first hours of operation of the pool.
Installation process sand-filter requires careful attention to the tightness of the compounds, since even the minimum air suction violates the hydraulic cycle. First, a system of collectors (drainage tubes) is laid at the bottom of the container, then quartz sand of the fraction of 0.45-0.85 mm is filled, after which the final assembly of the upper cover with the valve is made. It is important to strictly follow the sequence of operations described in the manual to avoid breakdown. switch-tube under the weight of sand.
After the physical installation of the system, a primary washing of the filler must be performed to remove fine dust that otherwise will immediately fall into the pool bowl. Turn the pump on in mode Backwash for 2-3 minutes until the water in the observation window or at the exit becomes transparent, and then switch the mode to the Rinse (Washing) for 30 seconds to seal the sand cushion. Only after these procedures can the valve handle be moved to the position Filter and start a full circulation of water.
The principle of operation and the device of the sand filter Bestway
The basis of the purification system is a reservoir, inside which there is mechanical filtration of water through a layer of quartz sand. Pressure-generated water pump-assemblyThe purified liquid passes from top to bottom through a sandy mass, where contaminants up to 20 microns are retained, after which the purified liquid returns to the pool. The key element of flow management is multi-passIt redirects water for different maintenance modes without having to shut down the pump.
The cleaning efficiency directly depends on the state of sand loading and the correct pressure in the system, which is displayed on the built-in pressure gauge. When pores are clogging in the sand, the pressure increases, which signals the need for the procedure. backwash. The design of Bestway provides for the presence of a viewing glass or indicator that allows you to visually monitor the degree of contamination of washing water.
⚠️ Warning: Never switch the position of the multi-pass valve handle while the pump is running. This can lead to failure of the valve gears or depressurization of the joints.
Modern models are equipped with timers and automatic switching systems, which allows you to maintain water quality without constant user participation. Understanding how they interact pump-impeller and filtering environment, helps to diagnose faster reduction of pressure or the appearance of noise in the operation of the device.
For maximum efficiency, use only special quartz sand for swimming pools, not building sand, as the latter may contain clay and dust clogging the system.
Step-by-step instructions for assembly and first start
Start by placing an empty tank on a solid, horizontal surface, preferably on a concrete slab or special substrates to eliminate vibration. Install the side or top valve according to the instructions for your model, making sure the sealing rings are lubricated with silicone grease and are free of damage. Connect the 32 or 38 mm diameter hoses (depending on the model) to the inlet and outlet openings, using adapters and clamps for secure fixation.
Loading the filter material requires special care: fill the tank with water by about a third to soften the fall of sand and protect the internal tubes collectors from impact. Fill the sand through the top hole, trying not to damage the fine elements of the internal distribution system, and fill the volume to the recommended level, usually 2/3 of the tank, leaving free space for the rest of the room. sand-spread when washing.
☑️ Pre-launch checks
After filling is complete, close the tank cover tightly and make sure that all latches or screws are tightened evenly. Before power is turned on, check again that all connections are dry and tightened, and the valve is in the right position to start the filtration cycle or primary washing. The first launch should be monitored to notice possible leaks or extraneous sounds in a timely manner.
Multi-pass valve operating modes
Water purification is controlled by turning the valve handle, which has several standard positions, each of which performs a function. Regime. Filter The main working position is where water passes through the sand and returns to the pool cleaned. Situation Backwash changes the direction of the flow, lifting the sand and washing the accumulated dirt into the drainage, which must be done when pressure increases.
Regime. Rinse It is used immediately after reverse washing to seal the sand cushion and remove the debris from the pipelines so that they do not get back into the pool. Position Waste It allows you to pump water from the pool directly, bypassing the filter, which is convenient when lowering the water level or removing large debris from the bottom.
- 🔄 Recirculate Water circulates through the pump, bypassing the sand load, used to mix chemical reagents.
- 🔒 Winterize - a position for preservation of the system for the winter, in which the water completely drains from the enclosure.
- 🚫 Closed - completely covers the flow of water, is used only if it is necessary to maintain the pump without draining the pool.
Some Bestway models may have additional notations or slightly different port locations, so always check the markings on a particular device. Misuse of modes, such as inclusion Backwash With clean sand, it will result in unnecessary water and electricity consumption.
The secret of long-term valve service
If the handle is difficult to turn, do not use force. Turn off the pump, relieve pressure through a stopper or remove the hose, and only after that change position.
Maintenance and filter washing
Regular maintenance is the key to clear water and long service equipment, the main indicator of the need for procedures is the gauge reading. When the pressure in the system exceeds the normal operating value by 0.1-0.15 bar (or about 20-25% of the initial), this is a signal that the sand is contaminated and requires a high level of pressure. backwash. Also signs of pollution can serve as a weakening of the jet from the nozzles of return and the appearance of turbidity in the water.
The washing procedure takes no more than 10-15 minutes and is performed in strict sequence: turn off the pump, move the valve to the position. BackwashTurn the pump on for 2-3 minutes, then turn it off again. Switch the valve to position RinseTurn the pump on for 30-60 seconds, turn off and return the handle to mode. Filter for further work.
⚠️ Warning: Water discharged from backwashing contains a high concentration of contaminants and chemicals, so divert it to sewers or away from beds and lawns.
In addition to hydraulic washing, once a season it is recommended to carry out mechanical cleaning of sand loading using special chemicals to dissolve organic matter and calcium deposits. If the sand was cemented, it must be replaced, since a normal washing will not restore it. filtering capacity.
Fault Diagnostics and Error Codes
Owners of Bestway pump and filter systems may face various problems that can often be solved on their own, knowing their causes. Below is a table of common faults, their symptoms and ways to eliminate, which will help to quickly restore the equipment.
| Symptom/Error | Probable cause | Elimination |
|---|---|---|
| Weak water pressure | Sand pollution, hose overbending | Perform a reverse wash, check the hoses |
| Pump noise | Air intrusion, cavitation | Check the tightness of the suction line |
| The water's not circulating. | Impeller clogging, engine failure. | Clean the impeller, check the power supply |
| Leak from under the valve | Wear of the sealing ring | Replace or replace the O-ring ring |
| Sand hits the pool | Collector damage, little sand | Check the integrity of the tubes, add sand |
If the pump emits a piercing squeal or burning smell, it is necessary to immediately disconnect the device from the network to avoid short circuit or fire. Often electrical problems are associated with unstable voltage in the network, so the use of a stabilizer or a separate line for the electrical system. pool-equipment It would be a reasonable decision.
Sand Replacement and Winter Conservation
Quartz sand is not a permanent material and requires replacement every 3-5 years depending on the intensity of the pool use and the quality of the water. Signs that the sand has exhausted its resource are the inability to restore normal pressure even after chemical washing, as well as the appearance of channels in the sand mass through which water passes untreated. To replace, you need to completely drain the water from the tank, remove the old sand and thoroughly rinse the insides of the container.
When preparing for the winter season, it is important not only to turn off the equipment, but also to properly preserve it so that the frost does not rupture the body or internal elements. After draining the water from the tank and pump, remove all removable parts, including the pressure gauge and hoses, and dry them. Put a little new sand in the tank or leave it empty, but be sure to close the holes with plugs so that rodents or moisture do not get inside.
Store the Bestway filter in a dry room at temperatures above zero, avoiding direct sunlight, which can destroy the plastic of the case. If there is no possibility to remove the equipment in heat, you can preserve it on site, filling the case with antifreeze for swimming pools or simply carefully clogging, but the risk of damage from temperature changes in this case remains.
The main rule of wintering: the water inside the body of the pump or filter expands when freezing and is guaranteed to tear metal or plastic, so a full drain is mandatory.
Frequently Asked Questions (FAQ)
How often should I change the sand in the Bestway filter?
Quartz sand is recommended to be changed every 3-5 years. However, if you use the pool regularly, have frequent parties or the water has increased hardness, replacement may be required more often, for example, once every 2-3 years. The signal is the inability to relieve pressure by washing.
Can we use regular river sand instead of quartz sand?
It's not recommended. River sand has an irregular shape of grains and different fraction, which leads to rapid silting, the formation of channels and breakdown of the collector. Use only special quartz sand fractions of 0.4-0.8 mm.
Why is the filter buzzing or vibrating?
Most often the reason is the air entering the system (check the tightness of the connections in front of the pump) or that the pump is on an uneven surface. Also, vibration can occur when the impeller clogs with foreign objects.
What happens if the sand gets back into the pool?
This indicates damage to the internal pipes-collectors (drainage) or that the level of sand is below the necessary. You need to drain the water, open the tank and check the integrity of the plastic elements inside.
Can the filter be left to work around the clock?
Yes, modern Bestway models are designed for long-term work, but it is more economically feasible to use a timer. Usually 6-8 hours of filtration per day is enough to maintain the purity of the water in inflatable and frame pools.
