Inlet Side Connection
Use flexible, compression-resistant hoses for connection to the
fixed installation (➔ noise reduction).
For fixed installation, use shut-off devices on both the inlet and
delivery sides of the pump
➔ important, for example, for maintenance and cleaning or for
shutting down the pump.
The hose connectors on the inlet side and delivery side must
only be tightened by hand.
Connect the hose to the 33.3 mm (G 1) thread on the
delivery side:
➔ To either the 120°-swivel and / or horizontal connection
➔ Seal the connection which is not required with a cap.
Recommendation:
Use compression-resistant hoses, for example the GARDENA
Profi Top Hose, 19 mm (3 /4") in diameter, Art. No. 4414
together with the GARDENA Quick Thread Coupling with
female thread Art. No. 7109 (with 33.3 mm (G 1) thread) and the
GARDENA Suction and High Pressure Coupling Art. No. 7120
(for 19 mm (3 /4") hoses) and a GARDENA hose clamp
Art. No. 7192.
Best results regarding the delivery capacity of the pump are
achieved when connecting 19 mm (3 /4") hoses.
Screw the GARDENA Suction Unit (Art. No. 1411 / 1418) to the
inlet side of the pump and screw tight by hand until the seal is
tight. Then submerge the suction hose in the liquid to be pumped.
Fixed Installation:
For connection to pipes or borse holes, we recommend using
the GARDENA Borse Hole Suction hose (Art. No. 1729).
Recommendation:
For suction heights exceeding 4 m, we recommend securing the
suction hose, e.g. by fastening it to a wooden peg, thus the pump
is relieved of load.
Don't use any hose connection system fittings on the inlet side!
