Note: check directly on the installed pressure switches for the
identification code of the assembled model.
Adjustment procedure (see image fig. H):
 completely loosen the regulating nut or screw "B" of
pressure switch 1 of pump no. 1 (in this you have the
minimum differential ∆P)
 start pump no. 1 by means of the manual control (or the
pilot pump when the set is provided with one);
 slowly close the isolating valve downstream of the set
until obtaining the desired stop pressure (reading on the
pressure gauge), adjust pressure switch no. 1 by rotating
the nut or screw "A" until the contact clicks open, this
operation will stop the pump;
 slowly open the isolating valve downstream of the set,
which causes a loss of system pressure until the contact
clicks shut for pressure switch no. 1(which is already set
with minimum P), this operation will start the pump.
Check the adjustment by increasing and decreasing the
pressure downstream of the system, always using the
isolating valve;
 perform the same operations for the set's remaining
pressure switches. To adjust the start and stop of the
pumps, use the information provided above in the
"Pressure switch calibration table". Pay particular
attention to set the starting values for the pumps following
the first one, with decreasing pressure values to prevent
the simultaneous start of the pumps;
 discharge the downstream pressure, set automatic
operation on the control panel, slowly open the isolating
valve downstream of the set, check the sequential
intervention calibration of the pumps at least twice to
further check the inversion of the starting order of the
pumps.

12. DISPOSAL

When discontinuing operation, the pressure booster set, or any
of its components, must be disposed of in a separated manner
according to what is set forth by the regulations in force in the
country where the set is installed.
For components such as the pump inverter panels and
pressure switches, see the specific component manuals
