User manual HAYWARD POOL EC40

[. . . ] Select a pump with an output rating of between 30 and 65 GPM (114-246 LPM). Since 40 GPM (150 LPM) is the desired maximum filter flow, a flow controller (part number ECX1055) is furnished with each unit for use with pumps rated between 40 and 65 GPM (150-246 LPM). Install the flow controller in the filter body as illustrated with an elbow adapter, union connector, or adapter. The adapter both secures the controller in its proper position, and completes the hydraulic balance of the system. [. . . ] To clean, first stop the pump, then move the bump handle down slowly, then up briskly. Open the filter drain and open the vent valve (Note: if the filter is installed below the pool water line, close the suction and return valves) and allow water and dirt to empty completely. After the filter has drained, and with the drain still open, run the pump for a few seconds to flush out any dirt remaining in the bottom of the filter. (Note: If the filter is installed below the pool water line, opening the suction valve for a few seconds with the pump off will adequately flush the unit. ) Close the filter drain and the vent valve. Start the pump and let the filter fill with water and repeat the CLEANING procedure. VACUUMING Vacuuming can be performed directly into the filter whenever needed. For fastest results, regenerate the filter before and after each vacuuming operation. 2. Superchlorinate the pool water by adding unstabilized granular or liquid chlorine. Stabilized forms of chlorine are recommended for normal daily use after the initial clean up of the water. Follow chemical manufacturer's recommendations for superchlorination and daily use. Caution: All suction and discharge valves must be open when starting the pump. Failure to do so could cause severe personal injury and/or property damage. Prime and start the pump following the manufacturer's instructions. When there is a steady flow of water returning to the pool, the filter is ready for precoating. DO NOT operate the filter for more than one minute without the precoat charge. (1. 8 kgs. ) of diatomite into the system through the skimmer as fast as the plumbing will take it. Note and record the pressure gauge reading after the diatomite has been added. This is the "precoat pressure. " FILTERING Filtration starts as soon as the filter has been precoated. As the filter removes dirt from the pool water, the accumulated dirt causes a resistance to flow. When the pressure rises 7-10 psi (. 49-. 70 Bar) above the precoat pressure, regenerate the filter. Restart the pump and filtration will resume at near the original flow and pressure. After each regeneration, and until the filter is cleaned, there may be a slight increase in the starting pressure. [. . . ] On the other hand, swimming pool water can be kept unfavorable to algae growth simply by maintaining a chlorine level of at least 0. 5 ppm in the water at all times. The chlorine level should be checked at least once a day using a suitable test kit. If an algae condition develops and the pool water "blooms" green, superchlorination of the pool will be necessary to clear it. Follow chemical manufacturer's recommendation for superchlorination.
