SAFetY iNStructioN AND wArNiNGS
Please read the user manual before using
the fl ow switch
Warning sign
1. iNtroDuctioN
We would like to congratulate you on the purchase of our fl ow switch. We appreciate your trust. That's why funtional
security and operational safety stands by us on fi rst 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 Fluomac is a device that enables pumps, with a minimum prevalence of 2 bar, to start and stop automatically, with
regard to a drop in pressure (opening of the taps) and to the stopping of the fl ow through the system (closing of the taps)
respectively.
Should the water supply be interrupted for any reason, Fluomac performs the important function of stopping the pump, thus
protecting it from harmful dry running.
It is also able to restart automatically, by means of an inbuilt timer, to check for the eventual presence of water (this function is
only available for versions with automatic reset function).
l The FLUOMAC is to be used exclusively for non abrasive clear water without debris and other dirt. In the opposite
case, an effective pre-fi lter with a mesh size should be installed no coarser than 0.2 mm in front of the device.
l It is not recommended to install the unit in wells or in dense enclosures, as strong condensation may occur. If there is a risk
of ice forming due to low ambient temperatures, it is recommended to protect Fluomac and the pump accordingly.
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.

4. oPerAtioN
The appliance activates the pump for
about 15 seconds when it is powered.
The pump starts every time it senses
a pressure drop within the system, for
example when a tap is opened.
Unlike traditional water system
equipped with pressure switch and
pressure tank, it is the minimum fl ow
that determines when the pump should
stop, rather than the cut-out pressure.
The device delays the pump from
stopping for a further 7 – 15 seconds,
thus reducing pump cycling in low fl ow
conditions.

5.a hydraulic connections
Fluomac can be installed either in
a vertical or a horizontal position,
anywhere between the pump outlet
and the fi rst outlet (tap). Care must be
taken to ensure that the direction of
the arrow on the cover is in the same
direction of the fl ow of the fl uid within
the pipes (fi g. 05). All hydraulic con-
nections must be properly tightened.
An adequate pressure reducing unit
must be fi tted on the delivery port of
any pump exceeding 10 bar working
pressure.
AchtuNG: cAutioN: with the exception of submersible pumps, installing a non-return valve between the
pump outlet and the Fluomac inlet may adversely affect pump operation. (the pump may fail to stop). if it is
necessary to install a non-return valve, this must be mounted at least 3 meters away from the device (fi g. 04).
In the case of very high fl ow rates, the Fluomac device can be installed in a „by-pass" mode, in parallel with a non-
return valve placed on the main outlet, as shown in Fig. 06, to reduce pressure drop.
5.b electrical connections
All electrical connections should be carried out by qualifi ed personnel only, as shown in Fig. 3.
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.
In the case of pumps with power exceeding 500 W and an ambient temperature greater than 25° C, heat-resi-
stant cables (resistant to at least 105°C) must be used. Use only the terminals supplied with the device.
In the version in which the connecting cable is included, simply connect the power plug of the pump to the
Fluomac's electrical socket and the Fluomac device's plug, into a power outlet.
Note: the units supplied with 1 mm2 cables is suitable for maximum loads up to 10A.
cAutioN: the pump connected to Fluomac must be adequately protected against current overloads.
