SAFETY INSTRUCTION AND wARNINGS
Please read the user manual
before using the device
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 Fluomac®. 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. Please always download the latest ver-
sion of the user manual of www.profi -pumpe.de under „downloads". This shall
always prevail.

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).

Warning of electrical voltage
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 coar-
ser 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 opera-
ting conditions. When in doubt, the operation is prohibited.
Transport damages are reported immediately to the transport company and to us in writing.

3. PARTS AND COmPONENTS

Fig.01 shows the major components:
a. Inlet connection
b. Outlet connection
c. Mains indicator
d. Fault indicator (dry running)
e. Reset button
f. Supply terminals
g. Load terminals (pump)
h. Cut-in pressure adjustment screw

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 equip-
ped with pressure switch and pressure
tank, it is the minimum fl ow that deter-
mines when the pump should stop, rat-
her than the cut-out pressure. The de-
vice delays the pump from stopping for
a further 7 - 15 seconds, thus reducing
pump cycling in low fl ow conditions.

5. INSTALLATION

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 ensu-
re 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 connections must be pro-
perly tightened. An adequate pressure
reducing unit must be fi tted on the deli-
very port of any pump exceeding 10 bar
working pressure.
In the case of very high fl ow rates, the Fluomac® device can be installed in a „by-pass" mode, in par-
allel with a non-return valve placed on the main outlet, as shown in Fig. 06, to reduce pressure drop.

CAUTION: with the exception of submersible
pumps, installing a non-return valve between the
pump outlet and the Fluomac® inlet may adver-
sely affect pump operation. (The pump may fail to
stop). If it is necessary to install a non-return val-
ve, this must be mounted at least 3 meters away
from the device (fi g. 04).
