Frequently Asked Questions - Wasserwerk 250 Blumfeldt

How to install the Wasserwerk 250 pump?

Fasten the plastic bolt under the solar panel, connect it to the control unit, place the submersible pump at the bottom of the pond and secure it with the suction cups. Connect the desired nozzle to the fountain hose and connect the hose to the pump. Let the pump sit in full sun for at least 8 hours before first use.

Does the pump work in cloudy weather?

Yes, sunlight even on cloudy days (during daylight) is enough to run the pump thanks to the solar panel. The battery ensures continuous operation even without direct sunlight.

Why is the pump no longer working?

First check that the control unit is turned on (ON indicator). Make sure the solar panel is properly connected and the battery is charged. If the pump still does not start, clean the filter and impeller. If after 12 to 18 months the pump stops working, the battery may be exhausted and needs to be replaced.

How to clean the pump?

Remove the pump and impeller covers (see illustration in the manual) and wash both parts with clean water. Do not use abrasive products or harsh cleaners.

Is the battery replaceable?

Yes, the battery can be replaced. Open the housing as shown in the illustration and install a battery with the same specifications (6 V, 4 Ah).

What is the maximum water jet height?

The maximum delivery height is 1.2 m and the water jet height is 0.6 m.

Can I use the pump at night?

Yes, the pump can operate at night thanks to the battery that charges during the day. The LEDs automatically turn on in darkness to illuminate the fountain.

What to do if the flow rate decreases?

Reduced flow may be due to a filter or impeller clogged with sediment or dirt. Clean the parts as indicated in the manual. Also check that the battery is sufficiently charged.

Does the solar panel need to be oriented in a certain way?

Place the solar panel in a flat, sunny location without water accumulation. Orient it southward (in the northern hemisphere) for maximum sun exposure.

Can I use the pump in a pond with fish?

Yes, the pump is designed for freshwater ponds up to 50°C. Ensure the pump is fully submerged and that fish cannot be sucked in. Use the suction cups to secure it to the bottom.

• Do not place the solar panel in hollows or holes where water is likely to accumulate. Please ensure that you select a level location with a firm base. The plastic bolt should be inserted into sufficiently solid soil.
• Do not place the device on other devices that may become hot. This heat could damage the device.
• Do not use volatile liquids such as bug sprays. Excessive pressure when wiping the surface can cause damage. Rubber or plastic parts should not be in contact with the appliance for a long period of time.
• Children over 8 years as well as mentally, sensory and physically impaired persons may only use the device if they have been informed in detail about the functions and safety precautions by a supervisor responsible for them beforehand and understand the associated risks.

INSTALLATION

General information

• The pump is suitable for fountains or small ponds. The solar panel supplies the pump with the necessary operating voltage and charges the battery.
• Light sunlight and even cloudy skies are sufficient (in daylight) to operate the pump.
  The LED lights automatically illuminate the fountain in the dark.

Assembly

• Attach the plastic bolt to the underside of the frame of the solar panel.
• Connect the solar panel to the control box.
• Position the pump under water so that it is completely covered. Use the four flexible suction cups to attach the pump to the pond/well bottom. If the water is far too deep for the pump to reach the surface, elevate its standing position by placing stones or similar suitable material under it.
• Select the desired nozzle for the well and plug it onto the well pipe, as well as the well pipe onto the pump.
• Connect all parts as shown in the illustration.

OPERATION

Once the pump is installed and connected, allow it to spend at least 8 hours in full sunlight before using it.

Testing The Control Box:

• Press ON and make sure that the corresponding LED starts to light up.
• Press MODE several times to cycle through the different operating modes, which are indicated by changing LEDs (solar operation, battery operation).
• As soon as the solar panel is connected to the control box, the charging LED should light up to indicate the charging status.

MAINTENANCE AND CARE

Solar panel

The solar panel should be wiped regularly with a soft cloth, so that the light transmission remains guaranteed. Do not use abrasive materials or cleaning agents.

Pump

If after a while the pump no longer provides the usual throughput or stops working, check for sediment or dirt clogging the filter or pump. Remove the covers from the pump and impeller (see illustration) and wash both parts with clean water.

Battery

If the pump stops working after about 12 - 18 months in operation, the reason could be that the battery life has been exhausted. Open the housing according to the illustration and replace the battery with a model with the same specifications (6 V, 4 aH):
