5
.
2. Set the Run Time control knob

to Reset.
3. Reset the watering data as described in “Setting the watering data”.
If the Run Time knob
3
is not turned to Reset, 5 seconds after the battery
was inserted the current Run Time
3
and Frequency
2
settings shall
be accepted. This is confirmed by a double beep.
Note: The time the battery was changed is taken to be the starting time.
To ensure that the water timer works properly we recommend that you
insert a new battery at the beginning of every gardening season, or at
the latest after a year.
Important! Please dispose of used batteries properly at the appropriate
communal waste disposal site. Only dispose of batteries when flat.
12. Notes on Safety and Operation
.
The minimum water output to ensure that the Water Timer
functions correctly is 20-30 l/h.
For example, at least 10 x 2-litre Drip Heads are required to
control the Micro-Drip-System.
.
The Water Timer must be stored in a dry place away from frost
before the frosty season begins.
.
The max. temperature for the water flow is 40 °C.
.
The minimum operating pressure is 1 bar, the maximum operating
pressure is 12 bar.
.
For functional safety reasons, only use a 9 V alkali-manganese
battery.
.
The water timer beeps at intervals to indicate that the battery
capacity is too low until the battery is flat. When the water timer
is beeping the valve is no longer opened. To ensure that the
water timer works properly a battery with low capacity must be
exchanged.
.
We recommend fitting the water timer with a new battery at the
beginning of every gardening season or at the latest after a year.
.
The functional safety of the water timer depends on the capability
of the battery. The water timer will only run for approx. 1 year if
the new alkali-manganese battery has a nominal voltage of at least
9 V. Check the battery before you buy it.
