6. SECURITY TIPS
l Obey absolutely valid regulations on the electrical security
l To avoid shocks and re 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.
Warning: when the pump stops, the pipes are under pressure consequently we recom-
mend 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 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.
l Cleaning and maintenance must not be carried out by children without supervision.
THE MANUFACTURER EXPLAINS:
l To take over no responsibility in the case of accidents or damages on the basis of carelessness
or disregard to the instructions in this book.
l To reject every responsibility for the damages which originate from the improper use of the device.

7. SERVICING
It may happen occasionally that dirt is retained in the internal check valve and this is no longer
seals 100%. The rst remedy should be always trying to ush the check valve free. For this purpose, eg. As the Garden side faucet on full blast, so that the pump at full rated power promotes
about 30 minutes water. Is then the timing is not clear, the unit must be replaced. Prior to installation of the new device, the pump is in, free to ush any case, as previously described. Opening the
device on non-return valve is prohibited and always results in the loss of any existing warranty. In
addition, persons could be dangerous when Operating a clocking pump occur, so that the pump
may be operated under any circumstances continue. Until the device replacement, the pump must
be taken out of service. For abrasive materials such as sand, shortening the Maintenance period
and the device lifetime.
The following checks should be carried out regularly:
l functional test (min. every 3 months)
l integrity of the power cord
l Clean the guide lines (eg no buckling)
l Clean the media (no sand, no sludge)
