Please read these instructions thoroughly, before using the
GB
UV-C unit!
Use
This UV-C unit is suitable for use in garden or fish ponds helping to
clear 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
- Caution! UV-C radiation is dangerous to eyes and skin!
Do operate the UV-C unit only inside the casing. An integrated
safety switch protects against UVC radiation when the device is
open; the UVC lamp is lighted only when the UVC unit is
completely assembled! The correct function can easily and safely
be checked by the inspection glass (8) shining violet.
- 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 dama-
ged it must be replaced by the manufacturer or his customer service or
similarly qualified 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 electrical box (for indoor use only)
should be located in a water-protected area. They should be at
least 2 m away from the edge of the pond (see fig. A + B).
- Keep the plug dry!
- Pull out mains plug before starting to work on the UV-C unit,
garden or fish pond. (Disconnect the electrical box.)
- It is not allowed to run the UV-C unit when people are inside the
water!
- Do never immerse the UV-C unit in water and make sure that the unit
may not be flooded.
- Do never hang up or transport the UV-C unit by the cables.
- Avoid exposure to intense sunlight.
Start-up (see fig. A, B + 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 fixing stands (9) in a flood-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.
- A 1" thread can be connected to the inlet or outlet of these UVC lamps.
- With the included hose fittings hoses to the pump and to the filter can
be mounted directly.
10
- With 18 and 36 watt UVC lamps the 1"-1 1/4" joint (30) can be
mounted at connection B, swiveled into any desired position, and fixed
with the 28x3 O-ring (35), the 1 1/4" hose fitting (31), and the 1 1/4"
gasket (34).
- With the 9 and 11 watt lamps, the elbow hose connector with screw
cap and O-ring (23) can be mounted at connections A and B and
rotated 360°.
