The warning light (LED), if lighted, indicates that the power supply is present.<br />
3.3 Start<br />
CAuTION!<br />
Absolutely avoid dry operation. Start the pump only after having<br />
completely filled the plant.<br />
The pump can be noisy at start due to the presence of air. Such noise should stop<br />
after few minutes of operation. usually air is drained from the pump after short<br />
time.<br />
CAuTION!<br />
Do not touch the fluid or the pump when the temperature is greater<br />
than 60 °C. hazard of scalding by simple contact.<br />
the plant cannot be drained by using the pump.<br />
Settings concerning pump performance<br />
With the help of the selector potentiometer (fig. M), set the performance of the<br />
pump (head) according to the needs.<br />
The selector is set by the manufacturer on the position marked by a dot and<br />
the letter R. This setting is suitable for 80% of all one-family houses. Should this<br />
performance be insufficient, progressively increase the set value. Should this<br />
performance be excessive or should noise arise due to the speed of the pumped<br />
fluid, progressively reduce the calibration.<br />
Modify the performance of the pump (head) by rotating the selector potentiometer<br />
using a flat screwdriver, as given in the following table:<br />

factory Setting<br />
Proportional pressure control<br />
The performance of the pump are suitable for most of heating<br />
plants in domestic buildings (approximately 80% of systems).<br />
The pump head is reduced at falling water demand and increased<br />
at rising water demand.<br />
The warning light (LED) is green.
