SAFety InStruCtIon And WArnInGS
Please read the user manual before using
the flow switch
Warning sign
1. IntroduCtIon
We would like to congratulate you on the purchase of our flow switch. We appreciate your trust. That's why funtional
security and operational safety stands by us on first place.
to prevent damage to persons or property, you should read this user manual carefully. Please
observe all safety precautions and instructions for proper use of the AC10. Failure to follow the
instructions and safety precautions can result in injury or property damage.
Please keep this manual with the instructions and safety instructions carefully in order to at any
time you can restore them.
2. In GenerAl
The AC10 is a circuit device that an electrical load (pump) automatically switches on and off. The device monitors
the pressure and the flow in the pressure line. Depending upon the pressure or the flow rate, the AC switch 5 one or
more electrical consumers (MAX 12A) on and off.
The AC10 is to be used exclusively for non abrasive clear water without debris and other dirt. In the opposite case,
an effective pre-filter with a mesh size should be installed no coarser than 0.2 mm in front of the device.
Make sure after unpacking that the data given on the nameplate agree with the foreseen operating conditions. When
in doubt, the operation is prohibited.
Transport damages are reported immediately to the transport company and to us in writing.
3. InStAllAtIon
l The device is installed at any point between the outlet of the pump and the first collector, so that the direction of the
arrow on the side between the two 1 „connections with the flow direction of the fluid in the pipeline matches. Make sure
that the hydraulic connections are completely sealed. If a pump with maximum pressure used above 7 bar, a pressure
reducer at the entrance of the device must be installed. The pump controller is to be used only for pumps that produce a
minimum pressure of 2.5 bar at the device installation point.
l The electrical connection of the unwired version is after the electrical diagram (see paragraph. 13) produce. If a consu-
mer is used with a power more than 1.1 kW and the ambient temperature is higher than 25 ° C, must be used for the
wiring is not less than 99 ° C cable with heat resistance. For wiring, only use this specific pliers. When ready to plug in
wired version, it is sufficient to connect the power cord of the pump with the outlet of AC10 and shut the power plug of
AC10 to an electrical outlet the power grid on.
l The pressure at which the device starts is set to 1.5 bar, this pressure is optimal for most applications. It can be changed
by an expert by means of adjusting screw (top).
l The height of the water column above the AC10 should not exceed 10m.
Warning: no additional check valve should be installed between the pump and the AC10, as it sometimes
causes problems.
Pull power plug
Warning of electrical voltage
4. oPerAtIon
The installation must be performed by a qualified professional.
Please, check each time before using, the electrical connections and the cables are not damaged. Check
before the installation whether the electrical connections are earthed according to the statutory regulations
and are installed.
Also, it is NOT recommended to perform, for example, a cable extension. It is not certain whether this modifi-
cation is technically correct, so this warranty is void.
5. 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-sec-
tion 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 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 Operation can not be performed by children and young people under 16 and people with intellectual disabilities
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.
6. ServICInG
It may happen occasionally that dirt is retained in the internal check valve and this is no longer seals 100%. The first re-
medy should be always trying to flush 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 flush 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 circum-
stances 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)
7. GuArAntee reGulAtIonS
For all manufacturing and material defects, the statutory warranty applies. In these cases, we assume the
Exchange or appliance repairs. Shipping costs are borne by us only to the extent legally
