Maintenance - Italtecnica Sirio Entry 230 Manuel D'instructions

The sensor which detects the valve position is broken. Have the device checked by the
manufacturer.
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 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 "Inverter error" message often appears on the display a few seconds after the motor
pump is started
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 Entry 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;
- 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 Entry;
- 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 therefore advised not to remove the electronic card's protective cover
as this would lead to forfeiture of the guarantee!
