Safety information
Tetra has manufactured this unit to the current state of the art and the valid safety regulations. Despite of the
above, hazards for persons and assets can emanate from this unit if it is used in an improper manner or not in
accordance with its intended use, or if the safety instructions are ignored.
For safety reasons, children and young persons under 16 years of age as well as persons who cannot recognise
possible danger or who are not familiar with these operating instructions, are not permitted to use the unit!
Please keep these operating instructions in a safe place! Also hand over the operating instructions when
passing the unit on to a new owner. Ensure that all work with this unit is only carried out in accordance with
these instructions.
The combination of water and electricity can lead to danger to life and limb, if the unit is incorrectly connected
or misused. Do not operate the unit if persons are in the water! Always disconnect the power plugs from all
units in the water and from this unit prior to reaching into the water and starting work on the unit! Compare
the electrical values of the power supply with those on the type plate on the packaging or on the unit itself.
Only operate the unit when plugged into an earthed socket. The latter must have been installed in accordance
with the valid national regulations. Ensure that the protective earth wire is led to the unit. Only use electrical
equipment, adapters, extension or connection cables with an earthed contact which are approved for outside
use. The cross section of power connection cables must not be smaller than the rubber cables identified with
H05-RNF. Extension cables must meet DIN VDE 0620. Ensure that the unit is fused for a rated residual current of
max. 30 mA via a residual current-operating system (FI or RCD resp.). Keep the power plug and all connection
points dry! Protect the connection cable when burying to avoid damage. Electrical installations at garden ponds
must meet the international and national regulations valid for installers. Do not carry or pull the unit by the
connection cable! Never operate the unit if the cable or housing are defective! Dispose of the entire unit if the
cable is damaged, as the latter cannot be replaced individually. Never open the unit or its component parts,
unless this is explicitly mentioned in the operating instructions. Never carry out technical changes to the unit.
Only use original spare parts and accessories for the unit. For your own safety, consult a qualified electrician if
you have questions or encounter problems!

exclude flooding and such that it is not exposed to direct sunlight.
Connecting the unit (figures C,D):
Tetra recommends hoses suitable for a minimum pressure of 1 bar. Cut the
stepped hose connectors
(4)
to suit the hose diameter. Slide the union nut over the stepped hose connector
(4)
and fit the hose on the stepped hose connector
(3)
. Insert the flat seals in the union nut, screw the stepped
hose adapters
(4)
to the inlet
(13)
