20 Preparation of pressure booster pump (accessories)
Electrical system
Important!
Connect the pump only to plug sockets
with PE contact. In order to increase safety,
we recommend that the electrical circuit to which
the pump is connected has a ground fault interrupt
system with a residual-current circuit breaker with
a rated residual current of 30 mA. This applies
in particular for installation close to water tanks,
ponds, etc.
Hose connection
Important!
Ensure that the suction line or intake line
is connected at the marked position.
If the pump is operated in suction mode, ensure
that the suction line is kept as short as possible.
21 Initial operation, filling the pump
Fig.26: Filling the pump
Before putting the PFT High Pressure Pump into operation for
the first time, fill the pump with water so that the air in the pump
housing is displaced.
Fill the pump with water via the water filler plug (1) or the water
inlet (2).
Do not fill too quickly so that the air has time to completely escape
from the housing.
It is advantageous if the suction hose is also filled with water.
21.1 Putting the pressure booster pump into operation
Before operating the pump, observe the following instructions.
The pump must be installed in a horizontal position.
Both the suction line and the pressure line must be connected
before the pump is put into operation. Pay attention to adequate
dimensioning of both lines.
At least 1" for the suction line
At least 3/4" for the pressure line
The hose must be completely air-tight and the end immersed in
the liquid to be pumped to avoid drawing in air.
