1. Attach the piping, rigid or flexible, to the discharge port.
2. Support the piping independently to prevent it from weighing on the unit.
3. Install a check valve on the piping, at least 1 m (3.3 ft) from the discharge port.
4. Install a gate valve downstream the check valve.
5. For units without float to be used for automatic operation, install a device stopping the unit
when the liquid level reaches the minimum permitted limit, see Start and stop levels on
page 16.

• The supply cord is protected from high temperatures, vibrations, collisions and
abrasions.
2. Check that the power supply line is provided with:
• a short circuit protection device of appropriate size
• a mains disconnection device with contact opening distance ensuring complete
disconnection for overvoltage III category conditions
• an RCCB earth leakage switch with tripping current < 30 mA.
4.5.3 Guidelines for the control electric panel
the phase conductors, the protection
• Install appropriate devices for protecting the motor from overloads and short circuits:
• From short circuit, by the installer: aM fuses (motor start-up), or thermal magnetic switch
Thermal, by the installer: trip class 10 A overload thermal relay + aM fuses (motor startup), or start class 10 A motor protection thermal magnetic switch
• From short circuit, by the installer: aM fuses (motor start-up), or thermal magnetic switch
• If required, install phase failure sensitive thermal relays.
Motor protection from overtemperature
• Single-phase: the unit is equipped with built-in capacitor and thermal overload protection,
and stops automatically in case of overtemperature. After 2-4 minutes the thermal overload
protection gives the restart consent.
• Three-phase: Install an appropriate motor protector with D curve in the control panel, in
accordance with the current shown in the data plate.

5.2 Rotation direction check (three-phase motors)
1. Place the unit in the vertical position on a level and flat surface.
2. Looking at the unit from the top, start and then stop it immediately: the rotation direction is
correct if the unit impulse movement at start-up tends to turn it clockwise. This means that
the motor is turning clockwise as it should.
en – Original instructions
5.3 Starting and stopping
Float switch version
1. Connect the plug to the mains and/or turn on the switch: depending on the position of the
float, the unit stays idle or starts to operate.
2. With the unit in operation, check that:
• No liquid is leaking from the pipes
• There is no unwanted noise or vibrations
• There are no vortexes nearby the suction port
• Liquid is actually being pumped.
3. When the float reaches the low position (minimum liquid level), the pump automatically
stops.
Version without float switch
1. Connect the plug to the mains and/or turn on the switch: the unit starts.
2. With the unit in operation, complete the same checks as for the float version.
3. Once the unit has taken up liquid to the minimum level, disconnect the plug from the mains
and/or turn off the switch to switch it off.
