NOTES
1. Automatic means that when the controller
stops, the vent valve is opened with a delay de-
fined by window n. 126; when the controller
starts, the vent valve is immediately closed.
2. On command means that the vent valve is
opened or closed by means of window n. 122.
3. These commands remove the pump motor
supply for a short time. If they are used con-
tinuously, they can cause the pump stopping.

INLET SCREEN INSTALLATION
The inlet screen mod. 969-9316 prevents the
blades of the pump from being damaged by debris
greater than 0.7 mm diameter.
The inlet screen, however, does reduce the pump-
ing speed by about 10%.
The inlet screen is fitted in the upper part of the
pump, as shown in the figure.
The screen can be mounted on each pump.
The screen can be removed as shown in the fol-
lowing figure.
