place while tightening the swivel nut onto the garden tap.
Do not cross-thread the nut, doing so will damage the thread! Tighten the swivel nut by hand; do
not use any tools! Otherwise, the swivel nut may be damaged; loss of warranty!
• The lower three outlets have a quick-release coupling each to which you can connect the garden hoses
for irrigation.

Safety Instructions
Please read the operating instructions
carefully and pay particular attention
to the safety instructions. We do not
assume liability for any injuries/mate-
rial damages resulting from failure to
observe the safety instructions and in-
formation provided in these operating
instructions regarding the proper use

a) General Information
• The product is not a toy. Keep out of the reach of
children and pets.
• Do not carelessly leave the packaging material ly-
ing around. It may become a dangerous plaything
for children!
• Protect the product from extreme temperatures,
direct sunlight, strong vibrations and combustible
gases, vapours and solvents. Never expose the
product to mechanical stress.
• Please handle the product carefully. The product
can be damaged if crushed, struck or dropped,
even from a low height.
• Only clear, clean freshwater (temperature max. 38
°C) is permitted with regard to the liquid pumped.
The product is not qualied for the management of
drinking water; It is also not suitable for managing
corrosive/caustic, ammable or explosive liquids
(e.g. gasoline, heating oil, cellulose thinner), fats,
oils, salt water or waste water from sanitary facili-
ties.
• Check the product for any damage before putting
it into operation. Do not operate the product, if you
nd any damage.
• Ambient temperatures at the installation site,
should not fall around or below the freezing point
(<0 °C). This will cause the water to freeze; ice
has a bigger volume and will destroy it. Store the
product above freezing point in a dry place during
wintertime.
• Please also observe the safety and operating
instructions of any other equipment that may be
connected to this product.
• Please contact our technical customer service or
any other specialist, if you still have any questions
that are not answered in these operating instruc-
tions.
b) Batteries and rechargeable batteries
• Operation with rechargeable batteries is possible.
However, the operating time is reduced owing to
the lower voltage (battery = 1.5V, rechargeable
battery = 1.2V). Therefore, we recommend operat-
ing the product only with high-quality alkaline bat-
teries to ensure long and reliable operation.
• Keep batteries/rechargeable batteries out of the
reach of children.
• Do not leave batteries/rechargeable batteries lying
around; they could be swallowed by children or
pets. If swallowed, consult a doctor immediately,
it could be fatal!
• Check that the polarity is correct when inserting
the batteries/rechargeable batteries (pay attention
to plus/+ and minus/- signs).
• Make sure that batteries/rechargeable batteries
are not short-circuited, dismantled or thrown into a
re. There is a risk of re and explosion!
• Do not recharge normal, non-rechargeable batter-
ies; they may explode! Only charge rechargeable
batteries; use a suitable battery charger.
• Old or at batteries can leak liquid chemicals that
may damage the device. If not used for a longer
period (e.g., in case of storage), remove the in-
serted batteries/rechargeable batteries.
• Leaking or damaged batteries/rechargeable bat-
teries can cause acid burns if they come into con-
tact with the skin; therefore, wear suitable protec-
tive gloves.
• Liquids leaking from batteries/rechargeable batter-
ies are very chemically aggressive. Objects or sur-
faces coming into contact with these liquids may
be severely damaged. Therefore, keep batteries/
rechargeable batteries in a suitable location.
• Always replace the complete set of batteries/
rechargeable batteries. Do not mix batteries/re-
chargeable batteries with different charges (at
and half-discharged batteries/rechargeable bat-
teries).
• Use either batteries or rechargeable batteries;
never mix standard batteries with rechargeable
batteries. Use only batteries/rechargeable batter-
ies of the same model and type and from the same
manufacturer.
• For the correct disposal of batteries, please read
the chapter “Disposal”.
