6. SECURITY TIPS
Obey absolutely valid regulations on the electrical security
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 = 3OmA protection.
• Installation only in frost-proof areas without condensation. Thus not in cisterns, wells,
shafts, other damp or frost-prone rooms and containers.
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.
The electrical connections are always to be carried out by an authorised professional.
The device may be used by children aged 8 years and above as well as persons with reduced
physical, sensory or mental abilities or those who lack skills, experience and knowledge only if
they are supervised. These aforementioned persons should only use the appliance while
adhering to safe instructions and resulting dangers.
Cleaning and maintenance must not be carried out by children without supervision.
IPC-2 / IPC-3
When the voltage is higher than 270V shows this code, if the Voltage
is lower than 260V, then recover to normal working situation
When the voltage is lower than 100V shows this code, if the Voltage
is higher than 110V, then recover to normal working situation
When radiator temperature get to 80 °C shows this code,if the
temperature lower than 60 °C,then recover to normal working
situation
When pressure sensor damaged or disconnect shows this code,
recover to normalworking situation after people check trouble-shooting
When pipe pressure equal to 99% of pressure sensor pressure
shows this code,if the the pressure lower than 96% of the pressure
sensor pressure,then recover to normal working situation
When inputed three phase power open phase shows this code,
recover to normal working situation after people check trouble-
shooting
When exceed the setcurrent or load power shows this code, reco-
ver to normal working situation after people check troubleshooting
When motor with short circuit or over-current problems shows
this code, recover to normal working situation after people check
troubleshooting
