2.11 Anchoring the pump units
The correct seating of the pump is vital for its efficient
operation and its longevity.
The surface must be resistant enough to absorb the
stresses due to the pump unit without deformation.
In the case where the unit is fastened by anchor lugs or
bolts, it must be carefully wedged to prevent any defor-
mation of the chassis when tightening the bolts.

.
To check the alignment and coupling, use a set square to
control the axial misalignment and feeler gauges for angu-
lar misalignment.
Carry out the control at four points :
at the top - at the bottom - left - right

2. INSTALLATION (continued)
Correct
Bad alignment
Angular fault
It is important to control the alignment at every step of
installation in order to ensure that none of these steps
generates stress on the pump unit or the pump itself :
• after fastening on foundations
• after fastening the piping
• after the pump has operated at normal operating
temperature.
Do not rely on the flexible coupling to compensate for
misalignment.
2.13 Electric motors
WARNING
Dangerous voltage.
Can cause
injury and death
.
Check that the supply voltage matches the indications
on the motor rating plate.
Comply with the wiring diagram, make sure the wires are
rated for the power and take care with the contacts
which must be thoroughly tightened.
The motors must be protected by appropriate circuit
breakers and fuses.
Connect the regulatory ground connections.
Check the direction of rotation :
WARNING
Do not operate
without guard
in place.
This fundamental checking of the pump must be done
without any product, with the inlet and outlet circuit open
to the air, for example, to avoid any risk of an unexpec-
ted pressure rise. Start the pump empty to check the cor-
rect operation of the connections and check that the
direction of rotation corresponds to installation's inlet
and outlet direction. Follow the instructions below if
necessary to change the direction of rotation.
Three phase motor : switch any two wires of the current
supply.
Two phase motor : switch the two wires of the same
phase.
Single phase motor : comply with the instructions of the
manual supplied with the motor.
