Startup - Watts MQ 3-45 Notice D'installation Et De Fonctionnement

9.4 Startup

Before start-up, the pump must be filled with 1.2 to
1.5 gallons of water to enable it to self-prime,
see fig. 15. The pump is self-priming with a
maximum suction lift of 25 ft.
Fig. 15 Priming the pump
When started, the pump begins to self-prime.
When it has been primed, the pump will
automatically change over to normal operation.
If the priming has not been completed within
5 minutes, the pump will stop automatically and
attempt to restart after 30 minutes. It is possible to
reset the pump manually, see point 2 in the table of
section 10.1 Control panel.
WARNING
!
Running the pump at a higher inlet
pressure than recommended (40 psi)
can cause the pump to leak.
Watts will not be held responsible for
any damage to the pump and/or its
surroundings if this warning is not
followed.
