IMPORTANT: The instruction manual you are holding includes essential information on the safety measures to be
implemented for installation and start-up. Therefore, the installer as well as the user must read the instructions before
beginning installation and start-up.
Keep this manual for future reference.
To achieve optimum performance of the adjustable botton nozzle, follow the instructions provided below.
1. CHECK THE CONTENTS
Inside the box you will find 12 bags of nozzles with the instructions sheet.
2. GENERAL CHARACTERISTICS
These nozzles are installed on the bottom of the swimming pool, particularly in pools with an overflow
system. The propulsion at the bottom of the pool evenly spreads the chemical products inside the pool and
saves in heating costs.
Maximum flow – 5 m3/h. The flow can be adjusted in the nozzle itself.
The nozzle can be glued in ∅63 pipes of a nominal pressure inside of 6 atm. or 10 atm depending on the
model.
3. INSTALLATION
The nozzles will be spread out over the bottom of the pool depending on the available flow.
Before cementing the bottom of the pool, layout the system. The end length of the piping should be a PVC
∅63 PN 6 pipe in models 28230 and 28231 or PN 10 in models 28501 and 28502. Finally, the tube
should be aligned perpendicularly and be on level with the bottom (Fig. 1).
The base of the nozzle should then be stuck inside the tube with adhesive for PVC (Fig. 2). Ensure that the
nozzles are perfectly aligned with each other. You can place a label if you wish, on the upper part of the
base to prevent it from becoming soiled with cement. Finally, cement the bottom of the pool up to the level
of the nozzle (Fig. 3).
4. ASSEMBLY
Once the cement has set, remove the adhesive label and place the adhesive seal on the base of the nozzle
and then place the liner.
Place the flange using the corresponding screws (Fig. 4).
Cut the liner inside the nozzle and in models 28501 and 28502, first place the trim and then the inside
unit by turning to the left "CLOSE" (Fig. 5).
5. START-UP
The nozzle flow can be adjusted through the centre axle of the distributor cover using a screwdriver. Open
and Close are printed on the distributor cover. (Fig. 6).
6. SAFETY WARNINGS
•
The nozzle should be installed by qualified technicians.
•
Only adhesives designed for PVC should be used. All other universal products should not be used.
