2.0 INSTALLATION AND TECHNICAL FEATURES
2.1 General regulations
Pump installation must be carried out as follows:


In a ventilated environment and easily accessible to an operator for periodic maintenance.


counter pressure valve.


2.3 Electrical connections
2.3.1 Power supply
The pump is supplied, as standard, with a three-pole power cable, but without a plug. Connect the cable to a
suitable 230 Vac 50/60 Hz power supply, which can be with plug or with direct connection to the electrical panel
with a suitable disconnector .
If it is necessary to replace the power cable, this must be done by specialized personnel. Open the pump by
removing the 4 screws located on the rear of the case (see fig. 1 chap. 8) and connect the cable, through the cable
gland, exactly like the existing cable, using cable H05VV-F 3x0.75 mm2. Close the pump after connection.
2.3.2 Low level probe
Connect the black- BNC connector to the corresponding connector located at the bottom of the pump.
The input for the low level probe has an hysteresis of 3 seconds when the alarm is either activated or
deactivated.
