Notes on these Operating Instructions Translation of the original instructions from German. Please read these operating instructions carefully and observe the notes given. Use these operating instructions to familiarise yourself with the Rain Sensor, the unit’s features and proper use as well as with the notes on safety. A A For safety reasons, children and young people under 16 as well as anyone who is not familiar with these operating instructions may not use the Rain Sensor. The Rain Sensor must only be used to control the components recommended by the manufacturer. Keep these operating instructions in a safe place. 2. Proper Use A A The Rain Sensor is a measuring instrument; please handle it with care! The GARDENA Rain Sensor is intended for private use in domestic and hobby gardens, exclusively for outdoor use, to control sprinklers and watering systems by means of water computers1) taking natural rainfall into consideration. A A The Rain Sensor must not be used for industrial purposes or in conjunction with chemicals, foodstuffs, easily flammable and explosive materials. Compliance with the operating instructions provided by the manufacturer is a prerequisite to ensure proper use of the GARDENA Rain Sensor. The operating instructions also contain operating, servicing and maintenance conditions. 1) Water Computer 1030 and 1060, 1060 U, Water Timer Electronic T 14 and T 1030, Water Computer Plus C 1030 and Profi C 1060, GARDENA Valve Box V1/V3, GARDENA Watering Valves, GARDENA Pump Relay and GARDENA Flower Box Watering Set. 14 3.

How the Rain Sensor Works The Rain Sensor detects natural precipitation as shown in Fig. B: If it is dry (Fig. B1), a ray of light is sent from the emitting to the receiving diode: The watering programme remains activated. If it rains (Fig. B 2), the ray of light is diverted due water drops on the surface of the lens: The watering programme is de-activated. The watering is interrupted until the water drops are dried out on the surface of the lens. The duration of the dry-out period depends on the weather (humidity, temperature, wind, etc.). Keep the air inlets A free, to make sure that the Rain Sensor dries out faster. The response time of the Rain Sensor depends on the amount of precipitation. Without the cone 0, the automatic watering is interrupted at a precipitation level of approximately 1l/m2.If the cone was mounted, the response time is shorter. If the Rain Sensor dries out again, watering begins at the next programmed starting time. Watering can be initiated manually despite registered precipitation by using the On/Off function at the respective water controller. 5. Preparations for Use Before using the Rain Sensor you must 1. insert the battery, 2. choose the position for the Rain Sensor and 3. set up the Rain Sensor. GB 15 GB 5.1 Inserting the Battery (Fig. D) Note:The battery is not included. A A To achieve the maximum operating time of 1 year only a 9 V alkaline battery type IEC 6LR61 may be used. We recommend Varta and Energizer batteries. 1. Unscrew the lid of the battery compartment 8. 2. Insert the battery in the housing in the correct position 6. Note: Pay attention to the +/– markings in the battery compartment and on the battery. 3. Replace the lid 8 on the housing 6. 5.2 Choosing the Position (Fig. E) Position the Rain Sensor in a place which is exposed to natural rainfall. Important! Make sure that the Rain Sensor is only exposed to natural rainfall and that it is not in a place influenced by watering installations, i.e. sprinklers etc. Important! In order not to reduce its performance, the Rain Sensor should not be installed at or near soil (danger of contamination). 5.3 Assembling/Setting up the Rain Sensor A A When assembling or setting up the Rain Sensor make sure that soil and other foreign bodies do not penetrate the lens. This prevents the Rain Sensor working properly. Mounting the cone (Fig. C) To mount the cone proceed as follows: 1. Mount the cone onto the Rain Sensor according to fig. C. 2. Make sure the cone is in correct position (lugs move in guiding grooves). The Rain Sensor can be mounted either with the spike (Fig. F) or with the base 2. Fixing the spike (Fig. F) 1. Insert the spike 1 from above into the opening in the base 2 and screw the base/spike to the receptacle 5. 2. Insert the spike e.g. into a flower pot filled with gravel, until it stops. Note: Avoid fixing the Rain Sensor in soil, as soil may splash during rain and thus reduce the performance of the Rain Sensor. Note: Make sure that the Rain Sensor is inserted in a perpendicular position (90°) (Fig. F 3). 16 Mounting the base 2 (Fig. F 4) 1. Alternatively the Rain Sensor can be screwed on a firm ground, e.g. on the roof of the house, a stake or onto plates: Screw the base 2 without the spike ont...
