2. GENERAL CHARACTERISTICS

NET 'N' CLEAN emerging NOZZLES is a cleaning system installed in the bottom of concrete swimming pools which drives
and distributes the water with distributing valves. In addition to cleaning, it also reduces the cost of chemical products and
heating.
The nozzles turn on each other, turning 30º on each pulse.
It is very easy and quick to install, saving time in installation and levelling of tubes in the bottom of the pool.
3. INSTALLATION
The nozzles are spread out on the bottom of the swimming pool, bearing in mind that their radius of action will vary
depending on the flow per nozzle and the size of the output. (Fig. 1). To change the output surface, see the instructions of
point 5. CHANGING THE OUTPUT SURFACE and Fig. 4.
