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 priming stage. The LEDs will stop flashing. If the pump
does not prime itself, repeat the operation.
