Mounting installation kit
The installation kit for the Neptun ST jet stream must be covered with the enclosed building pro-
tection so that all threaded bushings are protected. Please mind the installation arrangement.
Installation
The installation kit must be fixed 180 mm below the water surface (fig. 1). The 4 threaded nipples
are used for the subsequent mounting of the nozzle frame (fig. 1). The other threads are used for
flange mounting (X-fig.1). With concrete pools only the 4 threaded nipple sleeves can are moun-
ted.
Film mounting

Mounting the base unit (fig. 2)
The site of the pump must be chosen as close as possible to the installation kit. In addition, make
sure that the pump is mounted voltage- and vibrationfree on solid base or a suitable panel. Fur-
thermore, you have to provide an outflow possibility as well as an adequate ventilation to prevent
a flooding of the site. That`s the only way how a trouble-free operation can be guaranteed.
The air valve must be mounted vertically upwards and above the water surface. All the pipe fit-
tings, required for a scheduled piping, are included. Should, however, extensions may be neces-
sary, keep the pneumatic hose as short as possible (max. 10 m), and don`t crincle or clamp it in
any way. In addition, make sure that in case of modified piping, only bends but never angles must
be used. Similarly, a piping of the next larger nominal size should be worth to compensate possi-
ble pipeline resistors.

The pneumatic hose must be placed and fixed on the control box (fig. 4/8)
Mounting of the inlet aperture (fig. 5)
Connect the air hose (5) with the nozzle frame and the provided air line connection from the in-
stallation kit. Then push the coil spring (7) over the pneumatic hose (6) and fix it through the fixing
bush at the on-off switch. Then run the pneumatic hose through the gland and tighten them by
hand. This is sufficient to ensure the tightness.
Attention!
In case of using inox-parts in the pool (ArtNr. 51.400.265, 51.400.266, 51.400.272,
51.400.270, 51.500.269, 51.500.270) please use the Keder (piping)as edge protection.
