1
Over-Voltag-
protection
In case of overvoltage, this code is displayed. If the voltage
drops, the device returns to the normal operating mode.
2 Under-Voltage
protection
In case of undervoltage, this code is displayed. If the voltage
rises, the device will return to normal operating mode.
3
Thermal
protection
When the heatsinks reach the max. temperature, this code is
displayed. If the temperature drops, the device will return to the
normal operating mode.
4
Sensor error
If the pressure sensor is damaged or disconnected, this code
is displayed. After troubleshooting, the unit will return to normal
operating mode.
5 Over pressure
protection
If the line pressure rises above the max. value, this code is
displayed. If the pressure decreases, the device returns to the
normal operating mode.
6
Open phase
protection
Self-test for incoming or outgoing power.
7
Overload
protection
If the max. permissible current is exceeded, this code is displa-
yed. After the error has been corrected, the device returns to the
normal operating mode.

6. SECURITY TIPS
l
Obey absolutely valid regulations on the electrical security
l
To avoid shocks and fire risks, read and follow closely the following instructions:
•
Always unplug the device from the mains before carrying out any work on it.
• Be sure that the electric line connecting the device to the mains and the extension
leads have a cross-section suitable for pump power and be sure that the electrical
connections are far away from any water source.
•
When Flow guard is used for swimming pools, ponds and fountains if is necessary
to use an automatic RCD with IDn = 30 mA protection.
•
Do not operate the device permanently in the sun (risk of overheating).
•
Installation only in frost-proof areas without condensation.
Warning: when the pump stops, the pipes are under pressure consequently we
recommend opening a tap to discharge the system before carrying out any work
.
l
The electrical connections are always to be carried out by an authorised professional.
l
The device must not be operated by children or persons with reduced physical, sensory or
mental capabilities. Persons with insufficient experience and knowledge may only use the
device according to instructions or supervision if they have been instructed in the safe use
of the device and understand the resulting dangers.
l
Cleaning and maintenance may only be carried out by qualified personal.
