USE AND MAINTENANCE MANUAL
START-UP
Before starting the pump, fill the suction pipe (2) and the pump body (8) using the filling cap (9). Close the cap after
verifying that there are no leaks. Open the closing devices on the delivery pipe (i.e. the water cock) so that air can be
released from the suction cycle.
Position the switch present on the terminal box cover on "1" and insert the pump plug into a 230 V alternate current
socket. The pump starts immediately.
BOOSTER SETS FLOTEC are self-priming. Therefore, it is possible to start them without filling the suction pipe with
water. However, it is still necessary to fill the pump body. The priming operation requires a few minutes. It may also
be necessary to fill the pump body with water several times, according to the length and diameter of the suction
pipe. If the electropump is not used for a long period of time, it is necessary to repeat all the operations described
above before starting the pump.
CHAPTER 6

ADJUSTMENT OF THE PRESSURE SWITCH

The pressure switch of BOOSTER SETS FLOTEC is pre-set by the manufacturer at 2 bar for the start-up pressure and
at 3 bar for the pressure required to stop the pump. According to the manufacturer's experience, these are the most
suitable values for the vast majority of installations.
To modify these settings, please contact a qualified electrician.
CHAPTER 7
USE OF THE BOOSTER SET WITH PRE-CLEANER
If the booster set is fitted with a pre-cleaner, follow the directions below. Before performing maintenance opera-
tions, disconnect the pump from the mains.
Before cleaning and replacing the filter cartridge, disconnect the pump from the mains.
Then, open the pressure discharge valve on the upper section of the filter head in order to depressurise the system.
The same effect can be attained by opening the cut-off valve on the delivery pipe (i.e. the water cock). Turn the
collar below the filter head clockwise (looking at the pump from the bottom). The filter container can be removed
only from the bottom in order to allow the cartridge to be disassembled.
To reassemble the components, perform the operations described above in inverse sequence. Before performing
the assembly operation, check that the O-ring on the pressure discharge screw and on the filter housing is not
damaged or dirty, cleaning or replacing it if necessary. Before the assembly, wet the O-ring with water.
At this point, the booster set can be started. To facilitate these operations, it is advisable to install a cut-off valve
upstream from the filter.
