inflate the tank to 1,4 bar (Fig. 3)
10. TROUBLESHOOTING
Motor does not start
(?) Mains voltage missing
 Check the power cable, proper plug connection and
mains fuse efficiency
(?) Motor protector tripped for overheating
 Remove cause for overheating (pumped liquid too hot?
Impeller blocked by foreign objects? Wrong voltage?).
 After cooling the pump will return to operate
automatically
Motor hums but does not run.
(?) Impeller blocked by foreign objects
 Check the free rotation acting with a screwdriver into
