Note
: In case of
supply voltage below 100V
, the lock
of the breaker may not latch and the pump might re-
start on its own after sufficient cooling. Take appropri-
ate precautions, if an automatic restart of the pump
may lead to a dangerous situation.
A warm up period (approximately 15 min.) is
required to ensure that the rated ultimate vac-
uum and pumping speed are attained.
