The accident prevention rules of the association of the industrial trade coope-
rative association for electric plants and working material are to be considered

3. Intended Use
This submergible pump is designed for the pumping of water in the garden
pond, fountain, water trays or similar. It can pump water via a gland or it may be
operated via enclosed ascending pipes with water sprinklers.
A solar module or a power supply unit with a voltage of 12 - 24 Volts can be used
as energy source. If used in combination with a solar module the pump will only
work if the solar module is exposed to sufcient solar radiation.
A battery box (accessory) is additionally available. When operated with
rechargeable battery, it is possible to attach an LED-lighting (accessory) onto
the ascending pipe. Thus, you will get an effect lighting of the water fountain.
The LED light rings are available in different colors.
The delivery rate of the pump can be adjusted via the controller on the front side
of the pump. The water pump does not have any ON/OFF-switch. The pump
starts pumping water as soon as it is connected to the power supply.
4. Overview
1. Ascending pipes
2. Water nozzle with a 3-stage sprinkler
3. Water nozzle for the water bell
4. Controller for the delivery rate
5. 5 m Connecting cable including plug
6. Connection of LED light ring
7. Locking for the pump case
4. Assembly and Start-up
1. Completely unroll the connecting cable on the pump.
2. Measure the depth of water of your garden pond.
3. Firmly connect the individual ascending pipes until the pipe protrudes from
the water surface. For the pond pumps Roma and Marino it is rst required to
screw an adapter piece with thread onto the pump output. In case the enclosed
ascending pipes should not be sufcient, you may also order those pipes as
spare parts from the manufacturer. Now attach the sprinkler with a triple nozzle
or water bell.
• Note: When using the water bell it is possible to adjust the diameter of the bell
by screwing in or out of the upper part.
• Note: Please make sure that the pump is not directly placed on the pond
bottom. A particularly high amount of dirt is sucked in here which would lead to
a fast clogging of the nozzles. Therefore, please place the pump approximately
20 cm above the pond bottom onto stones.
4. Depending on the use, the pump may be operated directly via a solar module, a
battery box or a DC power supply unit (12 to 24 VDC) and or a solar battery. Now
connect the plug with the socket on the solar module or the battery box. A cable
piece with open ends is included in the scope of delivery for the connection to a
power supply unit or battery. Please note that, in this case, the brown cable is
the positive pole and the blue cable is the negative pole.
• Note: The plug is protected against reverse polarity; please do not apply force
when plugging it in.
5. If the delivery rate of the pump should be too high, you
may reduce the amount of water. For this purpose, simply
rotate the controller at the front side of the pump clockwise.
Do not apply force when adjusting. The adjustment range
amounts to 45°.
4.1 Operation with LED Light Ring
- Only possible with the pump Milano or Roma
An LED light ring is available as an accessory or already included in the set. This light
ring is simply slid onto the ascending pipe.
The electrical connection is done via the socket on the pump. For this purpose, please
remove the sealing plug, insert the plug of the light ring into the socket and rmly
tighten the coupling ring. In doing so, please pay attention to the correct t of the
seal on the plug. Depending on the type of light ring, the lighting will immediately be
activated or via a twilight sensor.
5. Protection against dry Running
The pump is standard-equipped with a protection
against dry running. 2 sensor points at the side of the
case are installed for this purpose. The pump will work
if those points are under water. The pump won’t work
if one point should protrude from the water!
Those points have to be cleaned with a sponge and
water when servicing or cleaning the pump.

6. Service and Maintenance
In order to maintain the performance of the pump it is required to
occasionally, depending on the water contamination, rinse the pump with
warm water. For this purpose, open the case as follows:
Note: Please do not apply force when assembling and disassembling the
pump. The parts are very delicate and may break easily.
1. Disconnect the power supply of the pump
2. Remove the ascending pipe from the pump.
3. Push the two lateral locks into the position „OPEN“ and take if off to
the side.
4. Carefully open the pump case.
5. Take the pump out of the case.
6. Rotate the front cover of the pump by approx. 45° clockwise (illustration
1) and carefully pull the cover to the front (illustration 2). In doing so,
please pay attention to the ceramic shaft and the seal.
7. Carefully pull the impeller wheel out of the pump (possibly use small
tongs as an aid). (illustration 3).
8. Now carefully clean all parts with warm water.
9. Now carefully insert the shaft with the impeller wheel into the hole of
the pump. In doing so, pay attention to the tight t of the shaft and
brackets on both sides of the shaft.
10. Now carefully attach the cover onto the pump. In doing so, pay
attention to the tight t of the seal.
11. Now rotate the front cover by 45° anticlockwise into its initial position.
12. Now reassemble the pump in reverse order.
13. Pay attention to the correct t of the connecting cable through the
case.
The pump is now again ready for operation.
7. Malfunctions
The pump does not pump any water
• Is the pump completely immersed in the water? Protection against dry
running (item 5)
• Is the supply voltage connected with reverse polarity? Cable color
brown = positive pole, blue = negative pole.
• Pump contaminated? Cleaning of the pump, see item 6.
• Sensor points of the protection against dry running dirty? Clean the
points!
• When the pump is freshly immersed in the water, there may still be air
in the area of the pump wheel. This is why no water can be pumped.
Remedial action: ll water into the ascending pipe with a watering can
when the pump is applied.
