property damage.
•
Lay suction line always rising. If the suction height is more than 23 ft (7 m), a suitable suction
hose must be installed.
5.3 Connect pressure line
•
The pressure line conveys the liquid to be conveyed from the pump to the extraction point.
•
Screw the pressure line to the discharge nozzle (water outlet) (internal thread). Make sure
that the thread is not overtightened and damaged. Use appropriate sealants (e.g., O-rings,
gaskets, sealing strip, etc.). Check the connection for leaks. Leaky connections will cause
malfunction and can cause property damage.
•
Make sure that the pressure line is not loaded with its weight on the pump body. Attach
these as needed.
•
In case of permanent installation (e.g. domestic water supply) it is recommended to connect
the device to the pipe network with elastic hose lines to reduce noise and vibrations.
•
The pressure pipes or hoses connected to the pressure side should be as short as possible, as
straight as possible, not bent, and not half rolled up. The diameter should be as large as
possible.
5.4 Fill the pump
•
Use a suction line with a check valve, which prevents emptying of the suction line when filling
or stopping the pump.
•
Remove the locking screw on the filler neck.
•
Fill the pump via the filler neck with water until it overflows.
•
Screw the locking screw onto the filler neck.
6.
Operation
•
The pumps are not self-priming pumps. Therefore, the intake hose must first be equipped as
described below:
1.
Check valve with filter; This ensures that after switching off the pump, the hose and the
pump do not run dry. This part of the hose keeps the pumped water back.
2.
hose connection with coupling nut; this hose end is connected to the front of the pump.
3.
Both accessories must be securely fastened to the hose with hose clamps.
•
Before connecting the hose to the pump, it is best to fill it with water. Then you can connect
the three-way tap or another 1 in (25 mm) connection to the outlet of the pump.
•
Afterwards you have to fill the pump housing with water through the opening of the
integrated filter and close it again.
•
When commissioning for the first time, make sure that the pump housing is completely
vented
–
i.e. filled with water. If this venting is omitted, the pump does not suck in the
pumped liquid. It is highly recommended, but not urgently necessary, in addition to deaerate
the intake pipe or to fill it with water.
•
If both the pump housing and the hose are filled with water, you can turn on the pump with
the ON/OFF switch. The pump immediately starts pumping water.
-
Tilt the ON/OFF switch to position "I" to switch on the pump.
-
Tilt the ON/OFF switch to position "O" to switch off the pump.
•
When the pump is turned off again, the water remains in the pump housing and in the hose.
The next time the pump is turned on, it pumps water immediately. If the check valve has not
been fitted or if the valve and hose are not properly connected (hose clamp!), the pump may
run dry again and must be refilled to function properly.
•
The pump must not work when the inflow is closed.
