operating conditions for the pump.
➔ Position the pump at a safe distance (min. 2 m) from the liquid
to be pumped.
Don't use any hose connection system fittings on the suction side!
A vacuum-resistant suction hose must be used
• e.g. GARDENA Suction Unit, art. no. 1411.
In order to reduce the suction time, it is advisable to use a suction
hose with backflow preventer avoiding automatic draining of the
suction hose when the pump is stopped.
1. Screw a vacuum-resistant suction hose airtight onto the con-
nector
on the suction side of the pump
2. For suction heights exceeding 4 m also secure the suction
hose
(e.g. by fastening it to a wooden post).
This relieves the pump of the weight of the suction hose.
