 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.
