The S1-200 is manufactured with different pump heads to handle different water temperature ranges to ensure maximum efficiency. These ranges are called temperature classes.
The temperature class of your pump end depends on the suitable water temperature. The S1-200 is manufactured in three classes:
Temperature Class | Range in Celsius | Range in Fahrenheit |
2 | +20 – +30 °C | 68 – 86 °F |
3 | +30 – +40 °C | 86 – 104 °F |
4 | +40 – +50 °C | 104 – 122 °F |
The pumps have a tolerance range of ± 2 °C (± 3.6 °F) regarding the respective temperature ranges.
