7.4 Electrical connection
WARNING! Risk of electric shock!
Danger from electrical current must be eliminated.
• All electrical work must be carried out by a qualified electrician.
• Before any electrical connections are made, the pump must be de-energised and
protected against unauthorised restarting.
• To ensure safe installation and operation, the system must be earthed correctly
using the earth terminals of the power supply.
• Check that the power supply voltage is ~220/240 V. To access the terminal strip,
unscrew the 4 screws from the terminal box cover.
• The HiControl 1 can also be used with three-phase or single-phase pumps with a
current of more than 10A, using a relay switch (minimum contact capacity = 4 kW,
220 V coil).
• To connect the HiControl 1 to the pump use a robust cable fitted with a male
connector or a main power switch.
• The connection cable must be routed so that it never comes into contact with the
main pipe and/or the pump housing or motor housing.
• The pump/system must be earthed in accordance with local regulations. A residual
current device may be used for additional protection.
• Unscrew the cap from the terminal box.
• Remove the cap.
• Make the electrical connections as shown in the wiring plan (Fig. 6a and 6b).
6a: Single-phase pump connection
6b: Three-phase pump connection
• Put the cap back on the terminal box.
• Screw the cap firmly in place on the terminal box.

8.1 Filling
CAUTION! Risk of damage to the pump!
Never operate the pump dry.
The system must be filled before starting the pump.
1. Connect the HiControl 1 to the electrical power supply; the POWER indicator light
will turn on.
2. While priming the pump, hold the RESET button down.
3. Check that the pump is correctly primed, then turn on slightly one of the taps in
the system.
4. The pump unit will start automatically, and after 20-25 seconds, the manometer
pressure should be close to the maximum pump value. While the pump is opera-
ting, the ON indicator light remains lit.
5. Turn off the tap. After 4-5 seconds the pump will stop, but the POWER indicator
light remains lit. Any irregularities in pump function following these operations are
due to poor priming of the pump.
