ECD
The ECD will enter on the initial screen. Make settings of the starting pressure and the differential pressure in
the main pump controller. The start of other pumps already comes fitted by fault. For configuration follow the
ECD manual.
If the motor does not start or does not pump water, try to discover the cause of the irregularity in the list of most
frequent problems and possible solutions provided later in this manual.
7) MAINTENANCE
Regularly verify the pressure of the accumulator.
The pumps do not need any specific or programmed maintenance.
The panels or controllers require no maintenance.

9) COMMON MALFUNCTIONS, POSSIBLE CAUSES AND SOLUTIONS
MALFUNCTION 1: THE PRESSURE UNIT DOES NOT START
MALFUNCTION 2: THE PRESSURE UNIT DOES NOT STOP
MALFUNCTION 3: THE UNIT STARTS AND STOPS CONTINUOUSLY
MALFUNCTION 4: THE PRESSURE DELIVERED BY THE UNIT IS INSUFFICIENT
MALFUNCTION 5: THE PUMPS OPERATE BUT DO NOT DELIVER FLOW
MALFUNCTION 6: DISCONNECTION OF THE THERMAL STOP
MALFUNCTION 7: THE UNIT DOES NOT PRIME ITSELF
Pay attention to the messages that appear on the controller screen, as the electronics of the CKE/CPE units
performs various safety and operational tests on the device and reports on detected errors (see specific manual
of the ESD/ECD).
