• Lay the suction line from the water pick-up point to
the pump in a continuously rising slope. Ensure that
the suction line is not laid above the pump height;
air bubbles in the suction line delay and prevent the
suction process.
• The suction and pressure lines must be installed in
such a way that they do not exert any mechanical
pressure on the pump.
• The suction valve should be located deep enough
in the water to prevent the pump from running dry if
the water level drops.
• A leaking suction line will prevent the water from be-
ing sucked in due to air ingress.
• Avoid sucking in foreign bodies (sand etc.).
Installation of a pressure line
• The pressure line (should be at least 19 mm (3/4"))
must be connected directly or via a threaded nipple
approx. 25.4 mm (1") to the pressure line connec-
tion on the pump.
• During the suction process the shut-off devices
(spray nozzles, valves etc.) in the delivery line must
be fully opened to allow the air in the suction line to
escape freely.
9. Initial operation
m IMPORTANT!
You must fully assemble the appliance before using it
for the first time!
• Install the equipment on a solid and level surface.
• Unscrew the coarse filter screw (8) and remove the
coarse filter (9) as shown in Figure 3. Now you can
fill the pump housing with water via the coarse fil-
ter screw (8). Filling the intake line accelerates the
in take process.
• Assemble in reverse order.
• Open the discharge line.
• Connect the mains cable.
• Switch on the equipment with the power switch (12)
water can be suctioned in for up to 5 minutes (max
mum suction height).
• After pressure drop due to water consumption
switches the unit automatically on (switch-on pres-
sure approx. 1.5 bar)
• The domestic waterworks can be used for do-
mestic water supply in the inner area also be per-
manently installed. To avoid vibrations and noise
should be minimised. the pump with flexible
hose lines connected to the pipe network will be.
Anti-vibration material is also recommended, z. e.g.
a rubber layer, between pump and base to lay. En-
sure a stable Fixing of the container by means of
Screws that pass through the holes fit in the stand.
10. Electrical connection
The electrical motor installed is connected and ready
for operation. The connection complies with the appli-
cable VDE and DIN provisions.
The customer's mains power connection as well as
the extension lead used must also comply with these
regulations.
Damaged electrical connection cable
The insulation on electrical connection cables is often
damaged. This may have the following causes:
• Passage points, where connection cables are
passed through windows or doors.
• Kinks where the connection cable has been improp-
erly fastened or routed.
• Places where the connection cables have been cut
due to being driven over.
• Insulation damage due to being ripped out of the wall
outlet.
• Cracks due to the insulation ageing.
Such damaged electrical connection cables must not
be used and are life-threatening due to the insulation
damage.
Check the electrical connection cables for damage
regularly. Make sure that the connection cable does
not hang on the power network during the inspection.
Electrical connection cables must comply with the ap-
plicable VDE and DIN provisions.
Only use connection cables with the marking
„H05RN-F".
Connection type Y
If it is necessary to replace the mains connection ca-
ble, this must be done by the manufacturer or their
representative to avoid safety hazards.
The printing of the type designation on the connec-
tion cable is mandatory. For single-phase AC motors,
we recommend a fuse rating of 16A (C) or 16A (K) for
machines with a high starting current (starting from
3000 watts)!
