event of escape of the liquid. In this situa-
tion, turn off the pump and leave the sys-
tem to cool.
Never use the pump in the event
of cavitation, as this can cause
damage to the hydraulic compo-
nents.
Pressure on the downline side of
the pump (delivery side) must
never exceed the maximum op-
erating pressure PN as indicated on the
pump data plate (see "Application Limits"
Figure 3). Pressure downline of the pump
is obtained from the sum of the pressure
delivered and the pressure on the suction
side (gravity for installations with negative
suction head, aqueducts, or water system
where admissible or required).
1. Check that the shutoff valves downline
of the pump (delivery side) and upline
of the pump are in the open position.
2. When the pump is connected to the
power supply it runs a "starting pha-
se". The green led
FLOTEC logo shows up on the di-
splay (a) As this first phase ends,
the pump is not operating and the
display shows the writing STOP(b)

factory pressure setting, the pump

4. If the pump does not start properly and
does not quickly reach the working
conditions, then STOP the pump. The
pump could switch to PROTECTION
