8. Changing the Battery
To ensure the Water Timer runs safely, only a 9 V alkali- Amanganese battery (alkaline) type IEC 6LR61 must be used.
.Make sure you exchange the battery at the right time to prevent the Water Timer failing due to a low battery when you are away for longer periods of time. Make sure that the time the battery has been in operation and the time you are planning to be away does not add up to more than a year.
.The functional safety of the Water Timer depends on the capability of the battery. The Water Timer Electronic does not have a battery status display (acoustic or visual). The Water Timer Electronic will only run for approx. a year if the
Programs do not run while the battery is being changed.
For notes on changing the battery see “Inserting the Battery”.
9. Notes on Safety and Operation
.To prevent water penetrating the battery compartment the Water
Timer must only be mounted in a perpendicular position with the sleeve nut pointing upwards.
.The Water Timer opens as soon as you have selected the watering program. To avoid getting wet when operating the Water Timer the hose should be connected or the tap turned off before selecting the program. Alternatively, the control unit can be removed for operation.
.The Water Timer must only be used outdoors.
Warning! The Water Timer must not be used indoors.
.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.
.Check the filter in the sleeve nut 7 regularly and clean if neces- sary.
.Avoid tensile strain. Do not pull the hose connected to the Water
Timer Electronic.
.Only use clear fresh water.

To protect your Water Timer against theft, the GARDENA
The bracket on the
11. GARDENA Soil Moisture Sensor (Fig. E)
Together with the GARDENA Soil Moisture Sensor (Art. No. 1187) watering is controlled considering the soil moisture.
Assembly
The Soil Moisture Sensor is connected to the connection socket 6 on the back of the control unit (Fig. A).
How it works
If the connected Soil Moisture Sensor indicates there is sufficient moisture then the watering program is either interrupted or not initiated.
Note : Manual watering (function man On/Off) is still possible.
12. GARDENA Rain Sensor (Fig. F)
Together with the GARDENA Rain Sensor (Art. No. 1189) watering is controlled considering natural precipitation.
Assembly
The Rain Sensor, as an alternative to the Soil Moisture Sensor, can be connected to the connection socket 6 on the back of the control unit (Fig. A).
How it works
If the connected Rain Sensor indicates an appropriate amount of rain, the watering program is interrupted or not initiated.
Note : Manual watering (function man On/Off ) is still possible.
