Translation of the original instructions.
For safety reasons, children and young people under 16 as well as anyone who is not familiar with these operating instructions should not use the product. Persons with reduced physical or mental abilities may use the product only if they are supervised or instructed by a responsible person. Children must be supervised to ensure that they do not play with the product. Never operate the product when you are tired, ill or under the influence of alcohol, drugs or medicine.

Intended use:
The GARDENA Water Control is intended for private use in domestic and hobby gardens, exclusively for outdoor use, to control sprinklers and watering systems. The Water Control can be used for automatic watering during holidays.

DANGER! The GARDENA Water Control must not be used for industrial purposes or in conjunction with chemicals, foodstuffs, or easily flammable and explosive materials.

SAFETY INSTRUCTIONS

Important!
Read the operator’s manual carefully before use and keep for future reference.

Battery:
To ensure the Water Control runs safely, only a 9V alkaline manganese battery (alkaline) type IEC 6LR61 must be used! In order to stop the Water Control from failing because of a weak battery if you are away for a long time, the battery must be replaced when the battery symbol flashes.
Setting up:
The Water Control may only be set up vertically with the sleeve nut to the top to prevent water from penetrating into the battery compartment. The minimum water output to ensure that the Water Control 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. At high temperatures (over 70 °C at the display) the LCD display may extinguish. This does not affect the program in any way. When the computer cools down the LCD display illuminates again. The max. temperature for the water flow is 40 °C.

Avoid tensile strain.
Do not pull the hose connected to the Water Control.

CAUTION! If the control section is removed when the valve is open, the valve remains open until the control section is reattached.

DANGER!

Cardiac arrest!
This product makes an electromagnetic field while it operates. This field may under some conditions interfere with active or passive medical implants. To decrease the risk of conditions that can possibly injure or kill, we recommend persons with medical implants to speak with their physician and the medical implant manufacturer before you operate the product.
Risk of suffocation!
Small parts can be easily swallowed. There is also a risk that the polybag can suffocate toddlers. Keep toddlers away when you assemble the product.
