DAB BOOSTERSILENT Betriebsanleitung Seite 4

Booster with integrated electronics
Installation
The pump's inlet pressure should not exceed 2 Bars.
The maximum suction depth should be less than 8m.
The device will not pump liquid if the tap is more than 15m the level of the pump.
Due to the non-return valve in this model, the suction hose cannot be filled through the filler cap
on the pump.
Using of the pump
Plug the electric cable into the socket. The pump will automatically begin to run.
If the suction phase is not activated within 120 seconds, the pump will shut-off automatically. The pump will
then try 2 more attempts to self prime for 120 seconds each.
The electric pump is equipped with an integrated electronic device that allows the unit to automatically
intervene in the following ways:
Automatic operation of the pump
The pump automatically starts when a tap is opened and shuts-off approximately 10 seconds after it is
closed.
Dry- Run Protection
If the pump senses that it is not drawing any water, it will automatically switch-off after approx. 45 seconds.
The red "Alarm" LED on the electronic display will begin to flash. After having restored the flow of water to the
pump, press the RESET pad to restart the pump.
If the alarm persists, or rather the user does not re-establish the flow of water and reset the pump, the
automatic reset will attempt to restart the pump after 1 hour, 5 hours and 20 hours, and then once every 24
hours. The electronic display continues to signal the lack of water from the first intervention of the dry run
protection up until the pump starts to operate correctly: flashing red LED with one flash and one pause. After
having re-established the flow of water, press the RESET button to restart the pump.
Electronic display signals
Greed Led (Power) on.
The pump is connected to the main power and is ready to supply water (as soon as a tap is opened).
Yellow Led (Pump on) on.
The pump is supplying water.
Red Led (Alarm) with 1 flash cycles.
The pump is not functioning due to lack of water on the suction side: the dry running protection program is
activated.
4. RECOMMENDATIONS
To ensure the proper operation of the pump, it is important to comply with the following recommendations:
The pump should not operate with the delivery tap completely closed (except for electronically
controlled pumps).
The pump must never be allowed to run dry.
The diameter of the suction and delivery hoses must not be less than the relative inlet or outlet (25 mm)
of the pump. A hose with a greater diameter should ideally be fitted to the suction inlet when the suction
height exceeds 4 meters. Do not use metal connectors on the pump's threads.
Connect the suction hose including a foot valve avoiding counterslopes, traps, goosenecks and kinks in
the hose.
Place the pump in a level, stable and dry place, and away from inflammable or explosive substances.
Never expose the pump to the rain or direct jets of water.
Make sure that the mains power connections are not subjectable to flooding, avoid that the pump is
exposed to direct jets of water and do not immerse the pump in water.
