You’ll discover all the secrets of the simple, efficient, costsaving home irrigation system!

Water is carried by hoses, with an inside diameter proportional to the quantity of water and the distance covered. In mediumsize gardens, the diameter is normally 12 or 14 mm: a larger diameter is suitable if the garden is bigger, or when water pressure is low.

SPRAY NOZZLES

A family of products designed to “launch” water over a distance. With these spray nozzles, you can adjust the water flow according to specific needs: from completely closed to concentrated, to open, through to a fine sprinkle. For extra practical use, flow control is positioned on the handle. Or for even greater versatility, select a washing pistol with instant control trigger.

STATIONARY AND ROTATING SPRINKLERS

Stationary sprinklers are the simplest, without moving parts which increases the watering range. The water is delivered through one or more nozzles, with sprinkle or spray jets. These models offer excellent results with normal domestic water pressure. The rotating arm sprinklers are the most used. With fixed or adjustable nozzles with different jets, they allow the watering range to be varied and the best working position to be found, depending on the pressure.

PULSATING SPRINKLERS

The so-called “pulsating” sprinklers have a striker that breaks the water jet to distribute it more evenly. An original adjustment ring nut selects the areas to be irrigated. These sprinklers provide the longest range, and are used for watering large, obstacle-free areas.

OSCILLATING SPRINKLERS

Oscillating sprinklers cover rectangular areas, watering only where necessary. The area can be varied with the selector. The swinging arm sprays a fan of water into the air, which falls gently just like natural rain. The handy plug accessory can be removed for periodic cleaning of the nozzles.

HOSE CARTS

The hose is an important asset that will only last if cared for properly: after use, it must be drained of all residual water and put in a dry place, out of the sunlight. To store your garden hose neatly, without bends and twists, and to carry it without dragging, there’s nothing better than a hose-cart. Claber hose-carts also allow continuous water flow without having to extract the hose. Just unwind the length required: water flows through the hose-cart hub into the wound hose and out the other end.

HOSE REELS

Your hose will last even longer on sturdy and rigid wall-mounted reels. Designed for outdoors, they have rustproof aluminium frames, resin drums, and come in a simple kit for assembly without tools.

SHOWERS

After summer gardening, or even holidaying or camping, cool off under the tripod shower. Usable on all surfaces, this corrosionproof allaluminium shower connects directly to a water hose. Completely ismantles, thus taking up very little space.

“WIPPY-SYSTEM” WASH BRUSHES

What else can you do with water? Wash the car, the terrace or garden paths, clean the boat or the camper. All this while minimizing water consumption with Claber “Wippy –System” watercleaning ideas.

CARRY CART

The carry cart for cleaning up and collecting leaves, grass cuttings and rubbish in disposable PVC bags: another great Claber gardening idea!

ERGOGRIP

Not just ordinary tools, but ergonomic instruments offering top work efficiency and handiness. With the aerated grip, solid and attractive, thanks to double chrome plating, and moistureproof.

Supplying just the right amount of water to each plant, just when and where it's needed - this is the fundamental idea behind drip irrigation. A new technology, with a whole range of advantages for you
and your garden friends!

Frequent watering with a perfectly measured amount of water, without waste, increases oxygenation of the soil, and favours vigorous plant growth. Now you can create your own made-to-measure irrigation
system, large or small, to satisfy all your garden watering demands.

The starting point of the system is the PROGRAMMABLE WATER TIMER, which automatically measures the amount and frequency of daily watering operations. Water is supplied to the DRIPPERS and the MICROSPRINKLERS, which guarantee continuous, accurate flow.

Drippers can also be adjusted, to distribute just the right amount of water to suit the requirements of your plants, while accounting for the nature of the soil.

SAVING WATER

Drip irrigation will not only help you save time, but also that most precious resource for nature, and of course for your garden:
water. The pressure required by the system is in fact lower than that of conventional systems. You can also program a lower irrigation frequency for CLAY SOIL, where water penetrates less than in SANDY SOIL. In this way, distributed water is used right to the very last... drip.

IRRIGATION TIME AND FREQUENCY

Excessive or insufficient watering can seriously damage your plants. The VERSATILITY of drip irrigation now solves that problem; just observe the right watering procedure for the particular soil, plant and climate type, as indicated in the table below.

POTTED PLANTS

Around the house, on the balcony or the patio, the pot is one of the most frequent habitats for a large number of domestic plants. Drip irrigation is the single solution to the very different watering demands of your plants, and also eliminates the problem of shifting and relocating pots around the house. ONE or MORE WATERING LINES can be created, to cater for different irrigation time and frequency, thanks to targeted dripper types that can be easily arranged as required or set to operate at specific times.

VEGETABLE GARDENS AND GREENHOUSES

In vegetable gardens, different plants demand different types of irrigation. Plants with a more fragile disposition towards water, such as tomatoes, can be irrigated by drippers, thereby eliminating the risk of water build-up and the formation of fungus. Lettuce and recentlyseeded ground however require atering from above by micro-sprinklers fitted to support stakes, an arrangement designed to deliver a fine rain-like spray.

FLOWER BEDS AND LAWNS

Drip and micro-sprinkler systems offer a wide range of solutions to meet the requirements of all plants types and garden areas. For flowers, plants and shrubs, 90°, 180° and 360° micro-sprinklers are recommended, as are adjustable flow and self-regulating drippers, all designed to save water, because it is directed straight to the plant roots. Strip micro-sprinklers are best for long, narrow areas, such as garden strips. Small surfaces or plants with delicate flowers? Use micro-sprinklers, for a fine, natural rain-like effect. Large areas with flower beds or lawn sections? Rotary 360° micro-sprinklers are just the answer. All sprinklers can be installed on robust support stakes; sprinkling height can be adjusted as required to actual plant height. Microsprinkler jets may also be modified by the special adjustment valve.

ELECTRONIC WATER TIMERS
These battery-powered timers are the brains behind the RainJet system. All it takes is a few seconds to set a customised program on two separate lines; the timer will automatically control watering operations at set times, even when you’re away at work or on vacation.
AQUAUNO
Claber presents its extensive, innovative family of electronic water timers. Constructed in sturdy ABS, their attractive rounded forms reflect the very latest trends in ergonomic design. Take a look at their other original features, such as the valve with diaphragm with no mechanical parts, meaning no wear and minimal consumption – in fact a single 9V battery rovides enough power for a whole year. Operating pressure in all models between 0.1 and 10 BAR.

INSTALLING YOUR DRIP IRRIGATION SYSTEM

STEP 1

Fit the electronic water timer with the pressure reducer to the tap. The water is supplied through a 1/2" hose or directly by a 1/4" feeding tube; connect it to the water timer by means of the automatic threaded connector and the coupling.

STEP 2

The 1/2" hose can be used to create a veritable watering circuit ideal for large balconies; in this case, use the 1/4" feeding tube to connect each of the drippers.

STEP 3

The Claber hole puncher makes hose holes with the exact diameter required, for watertight connections between the hose and feeding tubes. The tool can also be used to adjust and tighten drippers.

STEP 4

Cut lengths of the 1/4" hose to measure. After making holes in the 1/2" tube for each branching, connect each length to the 1/2" tube by means of the 2-way connector. For greater flexibility and control of water flow to each branching, a tap can also be used for each feeding tube.

STEP 5

Fit the drippers to the 1/4" tube in such a way that they are near the plants to be watered, along the path of the tube marked out by the stakes. Once installation has been completed, all you have to do is set the water timer (and don’t forget to turn on the tap)!

With the new Colibrì System, all the advantages of the underground irrigation system are finally accessible for small gardens too. A simple, convenient idea, designed with DIY in mind, it comes complete with
everything the gardener needs: from the new Colibrì pop-up microsprinklers, 1/2" polyethylene tube, the push-on couplings for all types of lay-outs, through to the drainage valve (to protect the system from
even the coldest winters) and battery-powered timers, to ensure that lawns and gardens are watered at the best time of the day, even when the owner is away or on vacation. All this, with one extra advantage: total Claber quality, certified ISO 9001.

The Colibrì System has been designed especially for gardens between 50m2 and 200m2. All areas can be covered perfectly by selecting and combing different micro-sprinkler types: 90°, 180° and 360°. Irrigating with the right amount of water is good for the garden, and for the gardener’s pocket. Water is without doubt a precious resource - and thanks to the versatility, watering uniformity and low pressure requirements of Colibrì System micro-sprinklers, you’ll be able to use it to maximum advantage, down to the last drop. And you can also program the system watering cycles for the best possible time, whatever the climatic conditions or the type of garden, with the help of the table shown on this page.

PLANNING

To plan your own system, prepare a scale plan of your garden and use a compass to mark the circles (360°) or sectors (90° and 180°) of the areas to be watered, as shown in the example alongside. For best results, position the 90° sprinklers in the corners, the 180° sprinklers along the perimeter of the garden or the house, and the 360° sprinklers in open spaces. Now trace the path of the main tube to establish the required length. Refer to the table below for operating water pressure and performance data of each sprinkler.

INSTALLATION GUIDE

To install the Colibrì System, proceed as follows. First of all, plant a stake at each point where a sprinkler is to be installed. Now join the stakes with string to trace the path that will be followed by the main tube. At this stage, use a spade to mark out a trench along the path, pushing the blade to full depth. There’s no need to dig; simply work the blade back and forth, as illustrated, to make a space in the ground that is sufficient for the tube, without actually removing any soil or damaging the turf.
Once the path has been marked out, connect the 1/2" tube to the timer, then unroll it along the path and up to the first stake. Cut the tube to length with a pair of scissors, then fit the threaded tee (the connection can be made even more secure by using a clamp).
Screw the sprinkler onto the tee and set it temporarily on the stake, for example with a turn of insulating tape. Proceed with another length of tube and the next micro-sprinkler, and so on, until you have completed the entire circuit with the last sprinkler (or with the drainage valve or the plug).
Before laying the circuit in the trenches, test the system. Turn on the water and check that all areas to be sprinkled are completely covered by the 90°, 180° and 360° micro-sprinklers; if not, adjust their
range or the angle as necessary.
Once testing has been completed and all adjustments have been made, simply lay the tube with the micro-sprinklers in the trenches, then remove the stakes. Tread the turf back into place, and in just a few days all signs of the installation work will have disappeared.
Colibrì System micro-sprinklers are designed for easy and precise adjustment both of the watering range (i.e. the distance covered by the water jet) and of the operating position (for 90° and 180° models). To adjust the watering range, simply disassemble the top of the micro-sprinkler and rotate the screw with a 3 mm Allen key. To alter the jet angle, raise and rotate the micro-sprinkler shaft. Remember to carry out these operations before laying the circuit in the trenches; bear in mind also that the micro-sprinkler is factory-set to the maximum range.
For best results when installing Colibrì sprinklers, fit a collar, to protect them against sand and pebbles in the ground.

REASONS FOR CHOOSING A CLABER RAINJET UNDERGROUNF IRRIGATION SYSTEM

There are a lot of good reasons for installing an underground automatic irrigation system:
• The convenience of having your garden automatically watered, even when you’re away or on holiday (no need to find someone to come and look after the garden);
• The knowing that all areas of the garden will get the necessary amount of water, without waste, assuring maximum economy;
• No hoses above ground to get in the way of the lawn mower – sprinklers are flush to the level of the lawn and are hardly noticeable;
• Silent operation, causing no disturbance to neighbouring homes;
• Increased property value – no well-tended lawn can today afford to do without an automatic irrigation system.

HOW TO PLAN AN UNDERGROUND IRRIGATION SYSTEM

MEASURE THE WATER PRESSURE

Close all household taps. Fit a pressure gauge to an outdoor tap, then open it completely (STATIC pressure). Ask your plumber to lend you a pressure gauge, or hire one. Take the measurement at different times during the day and night.

MEASURE THE AVAILABLE WATER FLOW

Simply time how long it takes to fill a recipient with known volume.

PLANNING

Use a compass to mark the circumference or circle sectors reached by each sprinkler, until the entire surface is covered. For best results, position the 90° sprinklers in the corners of patches to be watered, 180° sprinklers along garden strips, and 360° sprinklers in open spaces. The examples given in this booklet show the arrangement necessary to cover long and narrow areas evenly. The circumferences, as seen in the examples, meet to guarantee total coverage of ground and the even distribution of water in all points.

DIVIDE THE AREA INTO CIRCUITS

Referring to the sprinkler output table, write in the water consumption (in l/min.) next to each sprinkler. Group the sprinklers into distinct areas (use different colours), summing progressively the water onsumption. Make sure that the water consumption in each area does not exceed the available flow.
You should aim at creating a well-balanced system, i.e. each circuit should have the same water consumption.

MARK THE LAYOUT OF TUBES

Starting from the point where the solenoid valves controlling each single circuit will be installed, mark in the tube connecting each valve to the sprinklers (previously grouped into areas), thereby drawing independent valve circuits. Since trenches will have to be dug to lay the pipes, mark in straight lines, avoiding as far as possible driveways, terraces and other obstacles.

The diagrams below give examples of the positioning of sprinklers. Bear in mind that:
- 90° sprinklers should be positioned in garden corners;
- 180° sprinklers should be positioned along garden strips;
- adjustable sprinklers are best used for 270° or irregular angles;
- 360° sprinklers should be positioned in central open spaces.

FLOW RESISTANCE

Don't forget pipe FLOW RESISTANCE: refer to the pressure loss table indicating the values to be subtracted from the original static pressure available. The DYNAMIC pressure obtained should be sufficient to guarantee correct sprinkler operation.

PRACTICAL INSTALLATION

Go into the garden and turn your project into an efficiently operating reality. A set of solenoids controls the opening and closing of irrigation circuits.

The water supply line to the valves is subject to the entire amount of static pressure (when the circuit is closed); for this reason it should be made from a watertight metal pipe.
As a rule, the diameter of the tube connecting the valves to the service line should not be less than the diameter of the valves.
It is also a good idea to fit a gate valve upstream to shut off the entire system when necessary, for example when maintenance work is required.

Once the solenoid valves have been 45 connected to the main water supply pipe, take your plan and mark the path of tubes of each sprinkler circuit. Plant a stake at each point where a sprinkler is to be installed. Now join the stakes with string (or with chalk powder on the ground) to trace the line of each circuit tube, from the solenoid valve to the sprinklers.

Use a spade to dig a trench at least 20-25 cm deep. This won’t take much of an effort, and should be enough to protect the pipes against winter frost.
To avoid damaging the lawn, heap the dug earth on plastic sheeting, then remove when finished.
At each stake, place a sprinkler and the threaded bracket extension coupling (before applying the extension, drill a hole in the tube with a 10 mm bit) on the ground.
Unroll the polythene coil, from the valves to the stakes, along the marked path. Put the “T” or connector
couplings and the drainage valves in the position for installation. Straighten the tube properly before cutting it to length (better too long than too short). Use a hacksaw to cut the tube; clean cut ends with a scraper before fitting compression connectors to ensure a completely watertight connection.

Once the desired coverage is obtained and the circuits have been arranged, lay the tube in the trenches. Make sure that the sprinklers are positioned flush to the terrain surface; the threaded extension supporting the sprinkler can be segmented to adjust sprinkler height. Now connect up
all tube lengths between the sprinklers and the valves. Fix the sprinklers in a vertical position (tie them to the stakes with string), then open the valve (in sequence) to test circuit operation. Shift the sprinklers as required to achieve perfect coverage of the watered ground.
At the end of installation, the circuit should be emptied of all residues and earth. To do so, simply unscrew the head from each sprinkler and open the valves; the water pressure will flush the circuit clean. Screw the heads back on the sprinklers, then fill in the trenches and level to the surrounding area (and the upper edge of the sprinklers). Your irrigation system is now complete and ready for operation, controlled by an automatic watering timer.
