It is critical to have both a good filtration system for pools, with their respective filters and their corresponding pump with a correct chemical water maintenance as well.
To function properly, it is estimated that the filter and pump should be located no further than 15 meters to the pool. The basic tasks with which a filter much be able to perform are: Filter, Backwash, Rinse, Recycling, and Draining.
The dimensions of the filter and the pump depends on the total volume in liters of your swimming pool, and the time allowed to recirculate the volume of water. It is recommended that the time allocated to clean your pool is between 6 and 8 hours. It is always recommended that the pump and filters are the correct sized models that you need. This will make sure your pump does not work consistently for too long, and this will mean economic savings in energy consumption and the lifespan of your equipment will be higher if they are not required to constantly be ran.
It is always a good long term investment to buy a pump and filter that is high quality although it might not be the cheapest. To have a higher flow rate for your pump you will also need to increase the size of the corresponding filter. This means that there is a direct relationship between the flow rate of the pump and the diameter of the filter.
NOTE: The order of suctions indicated in this figure may vary according to the particular installation of each pool
- F – Filter
- D – Draining
- C – Closed
- RL – Backwash
- RC – Recirculation
- OU – Out of Use
- R – Rinse
Filtration is only part of the work to be done to maintain a clean pool as well as chemical treatment as one without the other alone will not achieve what you desire.
By this we mean that the filter does not do much of anything unless it is accompanied by a good chemical treatment such as chlorine.
The water is drawn from the bottom of the pools through the outlet or bottom chamber and the surface of the pool through the skimmers, each reaching filter through their separate means with their corresponding valves and then returning to the pool through the return. These are installed on the opposite side of the bottom chamber and the skimmer, thus providing a total renovation of the pool water.
The filter itself composes the silica sand load, through which water is circulated downwards, retaining it between the water and the suspended matter filter.
After starting the filtration cycle and after some time you need to wash the filter should there be sand and dirt preventing the passage of water.
When the backwash is done reverse the direction of flow of water in the pools through the filter and then get rid of all the dirt and debris.
Bearing these in mind, the instructions which are detailed below should not represent any problem for your application.
Filters should be installed as close to the pool as possible and preferably at a level of 0.50 m. below the surface of pool water.
Important: Make sure to use the proper materials for the joints of the selector valve iron pipe, it is essential to use plastic accessories and Teflon tape.
To get the most out of your pump and filter, follow the instructions below:
1. Perform charging once the filter is located in its final position and the installation is complete.
2. Open the clam and raise the multiway valve. It will be noted that this is unhooked by a PVC pipe.
3. The opening of this pipe should be covered with glass so that no sand gets in it.
4. Remove sand reaching 2/3 of the height of the filter.
5. Remove the beaker and attach the multiway valve again.
6. Attach the stainless steel ring again, tightening the screws to prevent water loss.
Water level in the Pools
1. If the system has a skimmer (suction surface), the water level must be kept exactly in the middle of the suction mouth that is located on the pool wall. If this level is not reached, or exceeded, the skimmer does not work.
2. If no skimmer pools, the water level should be maintained at least 20 cm above the hub cleaner hose, thus air inlet will be avoided in this connection.
Priming the Pump:
1. With the pump stopped, put the handle of the multiway valve in the FILTRATION position.
2. Close all valves with corresponding system sucks (suctions: background, skimmer and cleaner)
3. Open the lid of the pump and fill with water to overflow correctly then close the lid.
4. Start the pump, and slowly open the valve suction line, leaving the other two suctions closed. Observe as the water enters pump; if this happens, open the pump until the system remove all the air in the pipe.
5. If after performing the above operation no water enters the pump, close the valve suction line and immediately stop the pump. Then repeat as indicated in points 3 and 4.
6. If you made the above operations on three or four occasions without achieving prime the pump, detailed control of the suction system should be made, because somewhere in the same there an air inlet which prevents the formation of suction required for priming.
Once the pump is properly primed you’ll need to stop it and put the handle of the multiway valve in the FILTRATION position.
Start the pump and during operation you should be regularly observing the gauge which indicates the degree of saturation of the filter.
The valves of the bottom of the pool and skimmer will open depending on whichever is the chosen function.
If the water surface is dirty, open the valve corresponding to the skimmer, keeping all others closed so you achieve good suction.
When the gauge indicates a pressure of 0.9 kg / cm2; it’s time to do a WASH.
Each load of sand forms thousands of channels of steps, which include all the materials it contains and which are retained in the filter and consequently the number of free channels the flow of water is constantly decreasing.
It is for this reason that the pressure rises progressively, reaching about 40% more than the initial pressure to clean the filter; this pressure varies by model and filter based on the losses of each facility recirculation, for example, if the initial pressure gauge reading is 0.65 kg / cm2, washing should be done when it comes to 0.90 kg / cm2 washing.
This will proceed as follows:
1. Handle multiway valve on WASH and the intake valve open bottom is attached.
2. Put the pump in operation.
3. The duration of this operation is about 2 minutes. The water used for backwash will drain along with all the dirt.
4. After these two minutes, one hour should be left without operating the equipment. Following this time it will be rinsed.
After backwashing the filter and installing a new one the water will flow in the pool for a few seconds leaving a murky color.
In order to avoid this cloudy water flowing to the swimming pools, there is a position in the selector valve.
Operate as follows:
1. Immediately after washing, place the handle in position RINSE.
2. Wait one (1) hour to start the pump.
3. Connect the pump for 1 min.
4. After this period, rinse the pump and put the valve handle in FILTERING.
This position sends the filtered water to drain.
In this position the selector valve made the passage of water from the pump directly to pool without going through the inside of the filter.
In the event that the pool cannot drain directly into the sewer drain at the bottom of the pool, emptying can be done through the filter pump. To perform this operation you must place the selector valve in the drain position. With the intake valve open you will need to turn on the pump.
Before connecting the drain, make sure that the skimmer valves are closed.
