MAINTENANCE
The electric pump does not need any special maintenance operation if used according to manufacturer's instructions. To prevent any
failure of the unit it is recommended to check the given pressure as well as the power consumption. As a matter of fact, less pressure
often means that the hydraulic parts of the pump are worn. Considering that bigger power consumption means that there are me-
chanical frictions inside the motor and inside the pump. The electric pump unit must be serviced and repaired by specialized personnel.
If required, it is allowed only the use of original spare parts.
PROBABLE CAUSE
The water bed level has gone down.
The pump cannot operate in dry conditions.
