gauge indicates 12 bar.
Constantly monitor the pressure
gauge and if required readjust the
valve. As the temperature

readjust the pressure to 12 bar
when required.

30 sec.

120 ml of water must be in the measur-
ing cup.

of the pressure tester.
Notices:
Should < 60 ml leak out, then the pump
is defective or there is a leak in the
water system.
Large deviations in indicated pressure
while measuring (± 4 bar) means that
the pump is defective.
