General Questions
What other bits do I need?
It uses the same plumbing supplies and tools as other irrigation systems, just a lot less. It should be born in mind that the watering head is under constant water pressure so all joints should be water tight, leak free and capable of taking continuous pressure. The local bylaws and water regulations should also be adhered to.
Does it require wires?
Yes, all Watering Heads are connected together in parallel to the Junction Box with 4 core (1mm squared cores or heavier) sprinkler wire rated for direct burial.
Can I use it with another irrigation system?
Yes and NO. There are important differences. Don't connect up the wires to other sprinklers/controllers! It uses a different voltage system and you could damage both.
Can I paint it?
Yes, but preferably only light colours. It is light in colour to keep the electronics inside cool from the sun. Dark colours may cause too much heating. Use paints designed for plastics. Be sure to remove the covers to paint them and protect the nozzle from any paint. Don't allow any paint build up in gap area (it would impede turning).
Will it do potted plants?
Yes, but it is likely to get the nearby area wet too. On a calm day, it is accurate and consistent enough to water a large pot or a group of pots, but there is likely to be a little spillage.
What are the limits on size and shape of a zone?
Zones can be almost any shape. It needs at least 3 and no more than 24 dots to define a zone. Generally it works best to work from the corner closest to the Watering Head and go around clockwise to set the dots. It does not handle concave shapes where it would need to water two different parts radially. For instance, looking from the Watering Head, a U-shape would be okay, but a C-shape would not. These complex shapes can be broken into smaller zones that can be handled.
How can I make it squirt farther?
The maximum range is affected by the height of the head. Mounting it higher will increase the range. Also, make sure the water pressure is above 3 bar (45 PSI), the higher the pressure, the further it can reach.How close can it water?
How close can it water?
It can put water directly underneath the head, but we suggest no closer than 15cm (6 inches) away.
Design Questions
Where do I put the Watering Heads?
You don't need any overlap like you find in other sprinkler systems unless the stream would be blocked by some object. Generally they work best at the outside corners of a house, perhaps mounted under the eaves (not too high because it still squirts up). The higher up you position the head, the further the range but the lower the accuracy. Another good location is in the center of a fence line. You can hook it up to wherever you have a water supply.
What pressure and flow are required ?
Ideally pressure should be 3-5.5 bar (45-80 PSI), lower than this will reduce the range of the unit. The maximum flow is approximately 4 litres per minute, the flow varies depending on how far away from the head is being watered.
