6 Connecting to a water
source
6.1 Connecting the Water Pump to
a Water Source
The water pump can take in water from rain bar‐
rels, cisterns and from flowing or standing water.
In order for the water to be taken in, the differ‐
ence in height between the water pump and the
water source must not exceed the maximum suc‐
tion head (a), 18.
The suction hose must be inherently stable to
prevent collapse in the event of negative pres‐
sure.
The suction strainer must be used.
Attaching the hose connections
► Stop the engine.
► Screw on union nut (1) together with connect‐
ing piece (2) and seal (3). Do this at both
openings.

6 Connecting to a water source
► Push clamps (1) onto pressure hose (2) and
suction hose (3).
► Push pressure hose (2) over connecting
piece (4).
► Push suction hose (3) over connecting
piece (5).
► Align clamps (1) centrally over the resistance
ribs of connecting pieces (2 and 3).
► Tighten the screws of clamps (1) firmly.
Pressure hose (4) and suction hose (5) are
firmly connected to the water pump.
► Place upper part of suction strainer (6) on
lower part of suction strainer (7) and turn it
anti-clockwise until markings (8) on upper
part (6) and lower part (7) are in line.
Upper part (6) and lower part (7) of the suction
strainer are firmly connected to each other.
► Push clamp (9) onto the other end of suction
hose (5).
► Push this end of suction hose (5) over the con‐
necting piece of suction strainer (10).
► Align clamp (9) centrally on the connecting
piece of suction strainer (10).
► Tighten the screw of clamp (10) firmly.
Suction strainer (10) is firmly connected to
suction hose (5).
► Suspend suction strainer (10) in the water
source so that it does not touch the bottom.
WARNING
■ Do not disconnect the water pump from the
water source during operation and allow it to
run empty.
Operating the water pump without the housing
completely filled can cause severe damage to
the pump.
