Frequently Asked Questions - 50947 WilTec

What is the WilTec 50947 used for?

The WilTec 50947 (CUF-6000) is a submersible UV clarifier with an integrated pump, designed to clarify water in ponds and aquariums by destroying bacteria, pathogens, and floating algae using UVC radiation.

How deep can the device be submerged?

The device can be submerged up to a maximum depth of 2 meters below the water surface. Ensure it is completely underwater before operation.

What should I do if the device runs dry?

Running the device dry can cause irreparable damage and voids the warranty. Always ensure the device is fully submerged before switching it on.

How often should I clean the filter sponge?

The filter sponge should be cleaned at least once a month. Regular cleaning prevents pump and UV unit damage from foreign bodies.

How do I replace the UV-C lamp?

Disconnect power, release the locking lever, turn the cylinder counter-clockwise until it stops, then pull out the lamp assembly. Replace with a compatible 9W UV-C lamp.

Can I use the device without the fountain attachment?

Yes, the fountain attachment is optional. You can run the device without it for simple water circulation.

What safety precautions should I take?

Always use a residual current device (RCD) with a rated current up to 30 mA. Never operate the UV tube outside its housing, and avoid direct water jets on electrical parts.

How do I store the device in winter?

Remove from water, clean all components, check for damage, and store in a frost-free place in a container filled with water to prevent seals from drying out.

What is the maximum water temperature for operation?

The maximum water temperature for continuous operation is 35 °C. Exceeding this may damage the device.

How do I clean the quartz glass sleeve?

Disconnect power, loosen screw ring 4, and pull the sleeve out of the connector. Clean gently with a soft brush and clean water to avoid scratches.

Resistance

• The temperature of the liquid transported should not exceed + 35 °C in continuous operation.
- No flammable, gas-forming or explosive liquids may be conveyed with this pump. This pump must not be used for other liquids, especially not for engine fuels, cleaning agents, and other chemical products!

Electrical connection

• The electrical connection is made to a 230 V \~ 50 Hz protective contact socket. Fusing at least 10 A.
  • The device is switched on and off with the built-in on/off switch (depending on the model).

Caution:

The CUF series includes UV clarifiers with an integrated pump. The devices consist of a pump and a UV lamp. The devices must not be operated if they are damaged or open, as the UV rays can damage the eyes and skin.

• This device should be placed under water. Make sure that the device is completely submerged in the water. The depth should not exceed 2 m.
• Do not switch on the device before it is in the water. Damage can occur if the device is operated without water.
• Please ensure that the device is on a solid surface and cannot tip over or fall over. Violent vibrations can damage the quartz glass tube it contains.
  • Only use the device if there is no evidence of damage to the cable or to the device itself.
  • The device must not be operated when people are in the water.
  • The maximum pressure that can be exerted on the device is 2 bar.

Operative range

This UVC device ensures healthy fish and clear water. You can use it in ponds as well as in aquariums. The water is pumped through the UVC device with a pump. There it flows past a UV lamp and is exposed to UVC radiation, which destroys the bacteria, pathogens and floating algae in the water. This will make the water clear.

Operation

1. The device is designed for use under water. Make sure that the device is completely submerged in the water. It must not be more than 2 m below the surface of the water.

2. If the water depth is not sufficient to completely submerge the device, it must not be used. There is a risk of irreparable dry-running damage to the device.

3. Parts of the UV lamp are made of glass; you must therefore ensure that the device does not fall or be hit hard. There is a risk of breakage.

4. Please install all parts completely before plugging in the power plug.

5. The device must not be used if there is any damage to it, the power cord or the lamp. Check thoroughly before commissioning.

6. Never operate the device without a filter sponge. The filter sponge should be cleaned regularly; we recommend cleaning it at least once a month. Operation without a filter sponge can cause damage to the pump and the UV unit from foreign bodies.

Installation and cleaning

Disconnect the device from the power supply when cleaning it or performing maintenance work.

Installation

1. Please connect parts 15, 16, 17, 20 and 21, select the desired fountain attachment and connect the entire structure to part 15.

2. Push the riser pipe together to the desired size and place the device in the water.

3. The fountain is optional and does not need to be installed if you just want to circulate the water for example.

Cleaning

1. Dismantle the fountain attachment and loosen the screw 22, open the two clips on the side of the device. You can now remove the filter cover.

2. Remove the filter sponge and the filter boxes and clean them or replace them if necessary. The sponge needs to be cleaned regularly.

UV lamp care:

1. Take the UV lamp and release the locking lever. Turn the cylinder counter-clockwise until it stops. Now you can pull out the lamp and change the UV lamp.

2. To clean the quartz glass sleeve, loosen screw ring 4 and pull the sleeve out of the connector.

Pump care:

1. Turn the pump cover counter-clockwise until it stops. Now you can pull the housing parts apart.

2. Pull the pump shaft out of the housing and clean it thoroughly with a soft brush and clean water.

Winter storage

1. Remove the device from the pool.

2. Thoroughly clean all components.

3. Check all components for damage.

4. Store the device in a frost-free place and in a container filled with water.
