DANGER
The pump must never be operated with the shutoff valve on the delivery side closed. The discharge valve must be opened
as soon as the pump has been started up, to prevent damage to the latter by an excessive increase in liquid temperature.
5.3 INSTALLATION OF NON-PRIMING PUMPS ABOVE THE LIQUID LEVEL (POSITIVE SUCTION HEAD) FIGURE 2
• Close the shutoff valve downline of the
pump (delivery side).
• Open the shutoff valve upline of the
pump (suction side).
DANGER
The pump must never be operated with the shutoff valve on the delivery side closed. The delivery valve must be opened as soon
as the pump has been started up, to prevent damage to the latter by an excessive increase in liquid temperature.
DANGER
If the pump has difficulty in increasing pressure, repeat operations 1 to 6.
5.4 INSTALLATION OF SELF-PRIMING PUMPS ABOVE THE LIQUID LEVEL (POSITIVE SUCTION HEAD) FIGURE 2, FIGURE 3 AND "INSTALLATION"
TAB1.
• Ensure that the pipeline downline of
the pump is free (delivery side)
• Open the shutoff valve downline of the
pump (delivery side).
• Open the shutoff valve upline of
the pump (suction side). refer to
installation Figure 2
• Open the valve near the pump to bleed
the air.
• Remove the filler cap.
The check valve in Figure 3 serves to prevent emptying of the pump under a siphon effect at the time of shutdown, so that liquid stays
in the pump body for subsequent start­up.
DANGER
If there is no foot valve or check valve on the suction port, filling must be repeated before each start-up.
DANGER
If the pump has difficulty in increasing pressure, repeat operations 1 to 11. If, after several attempts, the pump does not operate
correctly, see the fault section "quick troubleshooting guide"
DANGER
Operation with frequency converter
If the pump is connected to a frequency converter during start­up, the pump should run at maximum speed. If the pump does not prime
within 5 minutes, stop the motor and repeat steps 1 to 11.
• Remove the filler cap.
• Using a funnel, fill the pump body and
suction pipe completely with liquid,
until it overflows from the hole.
• Tighten the filler cap fully down.
• If a filler cap is fitted on the pipeline
downline of the pump (delivery side),
remove the cap and use the hole for
filling. Otherwise use the pump filling
hole.
• Using a funnel, fill the pump body and
suction pipe (Figure 2), or only the
pump body (Figure 3) completely with
liquid, until it overflows from the hole.
• Close the pump filler cap.
• If the filler hose is on the pipeline,
continue to fill the pipe and pump
until water overflows also from this
second hole.
INSTRUCTION MANUAL
• Start up the pump and slowly open
the delivery shutoff valve to ensure
bleeding of any residual air in the pump
body and accumulated pressure during
start­up.
• Insert the second filler cap.
• Start up the pump and wait for the
liquid to be pumped. The pump can run
for 5 minutes to attempt to activate
liquid suction. If the pump does not
generate pressure and flow rate,
repeat steps 1 to 11.
