SAFETY INSTRUCTIONS

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.

Important!

Read the operator’s manual carefully before use and keep it 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 penetrating 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 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 injure or kill, we recommend persons with medical implants speak with their physician and the medical implant manufacturer before they operate the product.
DANGER! 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.
