Subject to technical changes!
Release the conical nut slightly and adjust the bubble pot horizontally (both
axis) and with the direction of the flow.
Tighten the conical nut again.
Maintenance
Regularly check the bubble pot – at least once a year – if there is any debris
and if it is still correctly aligned. If there are lots of particles or weeds in the
water you have to check more frequently.
For cleaning you have to remove the three Phillips screws and the base plate at
the bottom of the bubble pot. For this the bubble pot can, but must not necessa-
rily be detached. Perhaps you have to slightly release the conical nut and to
turn the basin by 180°. After cleaning the bubble pot has to be adjusted again
to the direction of the flow. Attention: the bubble in pressure must be built up
again; see user instruction for Nimbus!

If the bubble pot is completely detached for
cleaning the bubble tube must be cut by 1
cm before it is connected again.

Installation of the bubble pot
The EPS 50 bubble pot is designated for the bubble-in sensor "Nimbus". It repla-
ces the old bubble pot for surface waters.
The EPS 50 bubble pot has a 1" T-piece which is suitable for all kinds of fixing-
possibilities. With 1" standard parts for plumbing it can be fixed to consolidated
and natural banks as well as to vertical walls.
The bubble pot has to be installed in the direction of the flow!
Lead the bubble tube through a conduit (metal or plastic) to the place where
the bubble pot has to be installed; see picture 2 and 3
Cut the bubble tube rightangled which a sharp blade (e.g. scalpel); see picture
1. Do not use scissors.
Put the tube as far as possible into the plug. The plug is designed in a way that
the basin can be turned without distortion of the tube. To disconnect the tube
push the plug towards the conical nut and pull out the tube. Cut the tube by
approx. 1 cm before connecting it again.
Screw the double-nipple (SW 41) on the pre-installed T-piece.
Screw the conical nut (SW 41) of the bubble pot on the double-nipple.
Example of application: Installation at embankment
Picture 2 shows a possibility to fix the bubble pot to consolidated or natural
embankments. The actual fixing is made by a 1" metal pipe (waterpipe) which is
digged / rammed into the ground or is embedded by concrete.

Example of application: Wall-mounting
Picture 3 shows two possibilities how the bubble pot can be fixed to a wall (jetty-
wall, sheet piling...) Note that the bubble pot must be fixed stable enough that it
does not vibrate even at high velocities of flow. For this purpose, as it is shown in
the left drawing, the metal pipe can be put into the bottom of the water to increa-
se the stability. If this is not necessary the open end of the T-piece must be closed
by a stopper (included in the delivery).
Adjust bubble pot to the direction of flow
To ensure a correct functioning of the bubble pot it is important to adjust it exactly
horizontal and in the direction of flow (max. tolerance +/- 5°). For this purpose
the basin has a ball-and socket joint which allows for adjustments by +/- 15°in
every direction.
