Example. If you have a pool with 2 nozzles per branch line and you want a radius of action of 1.8 m, one option would be to
leave outputs S4 and place a pump with a performance of 5 m3/hr * 2 nozzles = 10 m3/hr at 1.3 bars (load loss of the
installation).
For the good working order of the system, it is recommended that the sum of the output surfaces of the different branch
lines is similar, thereby avoiding sudden pressure and flow oscillations in the installation. If there is an access ladder to the
pool, it is advisable to place the S1 output of the nozzle in the upper steps so that water does not jet outside the pool.
Connections: type of pipe that there should be at the end of the piping to connect to the corresponding nozzle.

Nozzle 26985
It can be installed in a bushing pipe (no. 26) or in a Ø75 PN 6 pipe. In both cases, it should be aligned perpendicular to
the bottom allowing a ±4º error with the ball joint system of the nozzle and leaving the pipe projecting so that it can be cut
once the bottom has been finished. The area where it should be cut (Fig. 2) is indicated on the bushing pipe (no. 26).
Place the protection cover (no. 23) on the corresponding side if you have installed the bushing pipe (no. 26).
After cementing and placing the gresite lining, cut the projecting tube at the level of the bottom.
Place plenty of PVC glue inside the ball joint and on the outside of the housing body support (no. 13) (Fig. 3) so that the
two PVC parts are well fastened and to avoid water from flowing inside the ball joint. Then insert it in the pipe until it is
correctly aligned.
Press the protection cover (no. 23) in the housing body (no. 13).
ATTENTION VERY IMPORTANT TO GLUE THE INNER PART OF THE SWIVEL JOINT !
Nozzle 26986
It should be placed in a PVC Ø63 PN-6 pipe perpendicular to the bottom of the pool and projecting above the finished
bottom.
After cementing and placing the gresite lining, cut the projecting piping at the level of the bottom.
Insert the housing body (no. 14) dipped in glue, inside the pipe.
Press down the protection cover (no. 23).
