Electrical power supply

If the equipment is not working, the error is most likely due to an incorrect

terminal power.

1 - Check that it has been connected to a live electrical outlet.

2 - Check that the current is compatible with the equipment and that the terminal block ca-

bles are connected according to the electrical diagram specified in this manual.

3- Check that voltage (230Vx1) reaches the equipment and, if not, check the power cables.

3.1 - If the equipment has voltage, but the fan does not rotate, check if there is 5.5V in

continuous between the yellow and black cables.

3.2 - In case there is no 5.5V, check that there is 10V in continuous between the oran-

ge and black cables. If there is 10V, one of the resistors has been damaged and must

be replaced.

3.3 - If there is no 10V, the fan's 10V signal is damaged, the fan needs to be replaced.

Filters replacements

If the equipment has a luminous cor vermella signal light on, it means that the filters are

fully dirty and must be replaced (page 10).
