NOTICE
The priming process lasts no longer than 5 minutes. At the end of each
minute, Wilo-Isar BOOST5 stops the electric pump automatically for
5 seconds, then restarts it. And so on until Wilo-Isar BOOST5 is primed.
During this process, the LEDs will continue to flash. The priming stage
may be brought to a close by timeout (5 minutes) or the end of the prim-
ing stage. The LEDs will stop flashing. If the pump does not prime itself,
repeat the operation.
