Italtecnica Sirio Manuel D'instructions page 14

The pump is running at top speed but performance levels are low
The pump or the capacitor connection is not correct: check the electric wiring.
The pump runs in the opposite direction (three-phase model); check rotation direction.
The pump is damaged or there is foreign matter clogging the waterway.
When more water is required of the system, the pressure drops
This is a normal condition which is due to the fact that the device is unable to force the pump above its capacity curve. As a
result, once a certain capacity is reached, the pressure is no longer offset as the pump is already running at the highest number of
revolutions allowed. In these cases, a pump with higher performance levels should be installed.
 MAINTENANCE:
The Sirio is designed to keep maintenance requirements at a minimum. To guarantee the device a long working life and perfect
functionality, always follow the instructions below:
- ensure the device does not have to withstand temperatures of below 3° C; if this is not possible, make sure all the water inside
it is drained out to prevent it from freezing up and damaging the device's plastic body;
- if the pump is equipped with intake filters, carry out regular checks to ensure they are clean;
-
always ensure that the cover is closed properly and the cable conduit is tightto prevent water from penetrating from outside;
- switch off the power supply and drain the water from the system when it is going to be left unused for some time;
-
do not force the pump to run without intake water, as this could damage both the pump and the Sirio;
-
before using the device with any other liquids than water, contact the manufacturer.
- do not carry out any operations when the device is open
- wait 3 minutes before removing the cover from the device so the condensers can discharge.
WARNING: this device does not contain any parts that can be repaired or replaced by the end user. You are
thereforeadvised not to remove the electronic card's protective cover as this would lead to forfeiture of the guarantee!
