Maintenance - Italtecnica Sirio SR23251 Serie Instrucciones Para El Uso

The pump is running at top speed but performance levels are low
The pump might be running backwards. Try inverting the 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.

The error may be caused by a non-compliant power voltage. With the pump running, use a suitable gauge
to measure the voltage at the power terminals and determine whether the problem concerns
underpowering or overpowering. If it is the former, use a power lead with a larger section to reduce
voltage drops, but if it is the latter, contact the manufacturer.
 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

body;
- if the pump is equipped with intake filters, carry out regular checks to ensure they are clean;
- make sure the cover is always properly closed to prevent water leaking in 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.
