Never operate the UV unit when the
housing has been removed.
Electrical safety :
v
v
Inspect the equipment before use to
ensure that the pump and the UVC unit,
especially the power cable and plug, are
undamaged.
Do not use a damaged UVC unit or pump.
Do not use the light if the connection lead,
glass tube or the housing of the UVC unit
appear to be defective.
If the pump or UVC unit is damaged, please
have them checked by our GARDENA Service
Centre or an authorised electrician.
The UVC-unit and the pump must be operat-
ed via a residual-current device (FI-switch)
with a nominal fault current
≤
30 mA (DIN
VDE 0100-702 and 0100-738).
v
Please ask your electrician for his advice.
Mains power cables should not have a smaller
cross-section than a rubber sheathed cable of
the designation H05 RNF.
Extension cables must meet the requirements
of DIN VDE 0620.
The information on the model plate of the
UVC unit must match the power supply.
The connection cable of the UVC-unit and the
pump cannot be replaced.
If the cable is damaged the UV unit must be
scrapped.
Do not use extension leads, connection leads
or adapters without a protective contact.
The fountain pump must not be operated
when there are people in the water.
Swimming pools and garden ponds should
be designed according to international and
national design regulations.
v
Please ask your electrician for his advice.
Never carry the UVC-unit and the pump by the
cable. Do not pull on the cable to unplug the
plug from the socket.
Please protect the cable from heat, oil and
sharp edges. Make sure that connection
points remain dry.
Always unplug the equipment when dis-
mantling the set, when it is not in use and
before maintenance.
v
Always disconnect the UVC unit and the
pump from the mains before undertaking
any work on them.
For Austria
In Austria power cables should correspond to
ÖVE-EM 42, T 2 (2000) /1979 § 22 according
to § 2022.1. According to this standard units
used in swimming pools and ponds should
only be operated via an isolating transformer.
v
Please contact your electrician.
For Switzerland
In Switzerland mobile appliances which are
used outdoors, must be connected via a
residual-current device.
Notes :
Never operate the UVC unit without water
throughput.
Never let the pump run dry; running dry
generates heat and will damage the pump.
Sand and other abrasive substances in the
liquid cause increased wear and reduce the
output of the pump.
The temperature of the liquid used must not
be below 4 °C or above 35 °C.
Safety switch :
If the UVC light overheats, it is switched off
by the built-in thermal protection switch. The
UVC light switches itself on again automati-
cally when it has cooled down sufficiently.
Due to the integrated safety switch the lamp
only comes on when the UVC unit is properly
installed.
Positioning the filter :
v
Stand or bury the filter housing in a stable
position at least 2 m away next to the
garden pond.
The filter must be positioned higher than the
surface of the pond.
Bacterial Activity :
Extensive bacterial activity arises
from + 10 °C onwards.
The filter system is a biological system and
therefore, when newly installed, needs a few
weeks until it is fully effective.
If possible, the filter should be in permanent
operation from spring to autumn and should
not dry out.
