polluted pond water.
It is not allowed to use the unit in or on the side of swimming pools!
For all technical data please refer to the type plates.
Safety measures
- Cautio! UV-C radiation is dangerous to eyes and skin! Do operate
the UV-C unit only inside the casing.
Translucent connections allow you to check easily and safely that
the unit is working properly.
- It may only be used in garden ponds and in their protection area, if the
installations have been set up to comply with the code's requirements.
Please contact an electrician.
- The UV-C unit has to be connected to a regular safety plug socket
through a circuit breaker (ground fault circuit interruptor, 30 mA).
- Before use: Check whether mains connection and electrical box are
intact.
- The mains connection of the electrical box cannot be replaced. If the
connection is damaged the device has to be scrapped.
- If the mains connection between electrical box and UV-C unit is
damaged it must be replaced by the manufacturer or his customer
service or similarly qualifi ed personnel in order to avoid dangers.
- Mains voltage and type of current have to correspond to the data on the
type plate of the electrical box.
- The connection box and the UV-C unit should be located in a water-
protected area. They should be at least 3,5 m away from the edge of the
pond (see fi g. A + B)
- Keep the plug dry!
- Pull out mains plug before starting to work on the UV-C unit, garden
or fi sh pond. (Disconnect the electrical box.)

Start-up (see fi g. A - C)
Important! Make sure that water always passes through the UV-C
unit during operation.
Otherwise the unit could be damaged.
- You should only connect a pump with a max. delivery head of 10 m
(1 bar).
- The water temperature should not exceed 35° C.
- Fasten the UV-C unit by means of the fi xing stands (15) in a fl ood-proof
position.
- The quartz glass tube (2) will be polluted by the pond water, thus
reducing the UV-C performance.
This needs cleaning of the quartz glass tube (2) at regular intervals
according to the degree of pollution.
- The UV-C lamp (1) has a rated life of approx. 8000 hours. After that it
should be replaced, at least at the end of one season (from March till
October).
- We recommend you to run the unit 24 hours a day (continuous use).
Avoid frequent switching (on/off).
This will reduce the lifetime of the UV-C lamp.
- Connect the translucent connections of the UV-C unit to your fi ltration
system (hoses, pumps, fi lters...).
You should use only fl at gasket rings for sealing your hose connectors,
joining rings or sealing liquids may damage the threaded connection.
- The connections may be turned against each other. For this purpose you
should loosen and remove the union nuts (11) of the red end caps (9) and
slightly loosen the pressure plates (6) as well (see fi g. C).
Cleaning and changing the lamp (see fi g. C)
Dismantling
1. Follow the safety measures.

6. Pull the UV-C lamp (1) out with caution and replace it, if necessary.
Old lamps should not be broken and disposed of in the household
refuse. Please contact your local company responsible for refuse
collection.
7. Turn out the pressure plates (6) and draw the O-rings (7) from the
quartz glass tube (2).
8. Remove the quartz glass tube (2) carefully and clean it thoroughly. Do
avoid using any sharp instruments.
If the quartz glass tube (2) or the O-rings (7) are damaged, they should
be replaced.
Assembly
9. Carefully insert the quartz glass tube (2) into the casing and push the
two O-rings (7) uniformly.
10. Tighten the two pressure plates (6).
11. Put the UV-C unit into operation (connect the pump), make the water
circulate and check the pressure plates in order to see whether the
unit is water-proof. Do assemble only waterproof units completely and
connect these to the mains supply.
12. Insert the UV-C lamp (1) carefully into the quartz glass tube (2).
13. Put the lampholders (3) onto the lamp sockets. On one side there is
the starter socket (4) with starter (5) at the back of the lampholder (3).
