hoses, fixed piping etc. are connected to the pump on the pressure
side. This ensures that the pump can be completely filled with water (2 l)
(air can escape).
The pump is to be filled with 2 l of water.
3.3.2 Silent operation:
The pump is silent. This advantage can only be maintained with the
correct installation:
v Choose a low-vibration base (e. g. do not place on metal sheets or
plastic tanks).
3.3.3 Max. flow values:
The pump has a bypass valve to enable short suction times. If the hose
end is open and there are no devices connected, or if the hose diameter
is very large, the valve may not be able to switch from suction to pumping
mode due to the hydraulic pressure conditions. This may cause increased
operating noise. In order to enable the full pumping capacity, close the
water outlet for approx. 1 second while the engine is running (e. g. by kin-
king the hose). This allows the valve to assume its correct position, which
is audible as one click. In standard applications with connection devices
such as showers or sprinklers, this happens automatically.
3.3.4 Assembly of prefilter:
If a prefilter is too long, it can be assembled in another position
(e. g. horizontally) instead of vertically downwards.
4. MAINTENANCE
DANGER!
Risk of injury!
Risk of injury due to accidental starting.
v Unplug the plug of the mains cable from the mains socket.
4.1 To clean the pump:
DANGER!
Risk of injury!
Risk of injury and risk of damage to the product.
v Do not clean the product with water or with a water jet
(in particular high-pressure water jet).
v Do not clean with chemicals including petrol or solvents.
Some can destroy critical plastic parts.
v Clean the pump housing with a damp cloth.
4.2 To flush the pump:
After pumping chlorinated water, the pump must be flushed.
1. Pump through lukewarm water (max. 35 °C), possibly adding a mild
cleaning agent (e. g. detergent) until the pumped water runs clear.
2. Dispose of the residues in accordance with local waste disposal
regulations.
5. STORAGE
5.1 To put into storage [ Fig. S1 ]:
CAUTION!
Damage to the pump due to frost!
v Store the pump in a frost-free place.
The product must be stored away from children.
1. Unplug the plug of the mains cable from the mains socket.
2. Close any shut-off valves in the suction line.
3. Open any shut-off valves in the pressure line (accessories, water
stop, etc.).
Therefore the pressure line is depressurised.

4. Unscrew the screw connection
drain screw
(8)
by hand.
Therefore the pump is drained.
5. Tilt the pump in the direction of the drain (approx. 80°) so that the
pump empties completely.
6. Unscrew the suction hose and the pressure hose.
7. Tighten the screw connection
drain screw
(8)
by hand (do not use pliers).
8. Clean the pump (see 4. MAINTENANCE).
9. Store the pump in a dry, enclosed and frost-free place.
6. TROUBLESHOOTING
DANGER!
Risk of injury!
Risk of injury due to accidental starting.
v Unplug the plug of the mains cable from the mains socket.

6.2 To clean the filter [ Fig. T3 ]:
If the pump does not start or stops suddenly during operation, this may
be due to a clogged filter.
1. Close all existing shut-off valves on the suction side.
2. Open any shut-off valves in the pressure line (connection devices,
water stop, etc.).
This depressurises the pressure side.
