Solutions
Check the electrical connections
Relocate PRESFLO
Install a model with a higher start-up pressure (Pm)
Check the electrical connections and that the pump
is working
Reset PRESFLO
®
Wait for the automatic restart or press START to
restart manually (See Operation, point 4a)
Replace the pump with one with more suitable
characteristics
Install a model with a lower start-up pressure (Pm)
Wait for the automatic restart or press START to
restart manually (See Operation, point 4b). Remove
any cause of leakage from system or install an
expansion tank
Check if the setting of the maximum current (Imax)
is congruent with the data of the pumps' rating
plate. If after manually restarting the pump after
correctly setting PRESFLO
anomaly, check that the motor has no mechanical
or electrical problems.
Check that the valve is not blocked by any foreign
objects and clean if necessary
Check the hydraulic connections and repair any
leaks. If a leak cannot be repaired, install an
expansion tank
Make sure that all taps are turned off and that
there are no leaks within the system
Check that the valve is not blocked by any foreign
objects and clean if necessary
