Installation depth
Max. installation depth below static water level: 90 m.
Min. installation depth below dynamic water level:
Vertical installation:
The pump must be completely submerged in the water at start-up and during operation.
Horizontal installation:
The pump must be installed and operate at least 0.5 m below the dynamic water level. If there is a risk that the pump may be
covered with mud, it must be fitted with a cooling jacket.

Installing the pump in the well
The pump should be fixed with a safety cable which must not be taut.
Fix it to mouth of the well by means of a cable clamp.
Note: do not move the pump around by the motor power supply cable.

First start-up
Ensure that the pump has a minimum water delivery capacity equal to the flow rate of the chosen pump.
Do not start the pump until it is completely submerged in the liquid.
Start the pump and operate it until the pumped liquid comes out completely clean. Otherwise the check valve may be blocked or the
pump may be fouled.

Operation
7.1
Minimum flow rate
To ensure that the motor is cooled effectively, the minimum flow rate must never be set below a value of 0.25 m
Any sudden reduction in flow rate might be caused by the fact that the pump is delivering more water than the well is able to supply. In
this case, stop the pump and use the delivery valve to regulate the flow-rate to suit the well.
7.2
Built-in protective devices
The protective devices are incorporated in the Active Driver 230 V / 10.5 Amp. / 110 Hz (read the attached instruction manual).
The inverter is already set at 110 Hz when the system is switched on.

Maintenance and service
8.1
Contaminated DAB pumps
Note: if a pump has been used with a harmful or toxic liquid, the pump is classified as "contaminated".
When contacting DAB to request service for the pump, provide details of the liquid which has been pumped even before the pump is
sent to the after-sales service. Otherwise, DAB may refuse to take delivery of the pump for maintenance.
