Introduction
Thank you for choosing to purchase this quality product. To minimise the risk of injury, we ask you to always take some basic safety precautions when using this product. Please read this operating manual carefully and make sure that you understand it. Keep these operation instructions in a safe place.
General remarks
A booster pump is used when the normal water pressure feeding a reverse-osmosis system requires increase. The efficiency of the booster pump depends on the intake pressure of the supplied water. For correct operation, a typical reverse-osmosis system requires a water pressure of a minimum of 3.5 bar (50 psi). In case the water pressure is below 3.5 bar (50 psi), the system produces a smaller quantity of water with a lower quality.
Note! Our booster pumps have a pressure regulation screw. The pump is tested in the factory and set to ideal values. We wish to advise you not to modify these values, which could affect the output of the pump.
| № | Name | № | Name |
| 1 | Transformer | 4 | High-pressure switch |
| 2 | Solenoid valve | 5 | Low-pressure switch |
| 3 | Pump |
- The booster system (A) is ideally suitable for home use. It has a high-quality non-stop pump that supplies a constant water flow to the diaphragm and operates quietly. The pump has a ⅜″ connector (B, C); nevertheless, a ¼″ quick coupling (not included) can be used, too. These quick couplings can be screwed off or replaced if necessary. The pump is available with a large variety of motor voltages, delivery heights, and configurations.
- Please observe the figg. 1 and 2 regarding high-pressure switch (E), low-pressure switch (F), solenoid valve or four-way valve (D), transformer (G), etc.
