8.4 Installing the unit into observation wells of 3" in diameter
and above, without top cap, universal installation
For this installation case, an individual solution to fasten the OTT ecoLog 500 (3G)
must be found depending on the station. Example: fix the universal suspension
bracket using an M6 hex head bolt/hex nut laterally to the upper end of the
observation well.
Required accessories: universal suspension bracket, mounting bolts, e.g.: M6
hex head bolts, washers, and M6 hex nuts (all made of stainless steel).
How to install the OTT ecoLog 500 (3G) (example)
Preliminary work: If not already done, install batteries and SIM card, refer to
Chapter 5.
Drill 2 holes (Ø 6.5 mm, 40 mm apart) laterally into the upper end of the
observation well, refer to Fig. 15.
Attach the universal suspension bracket to the observation well using two M6
hex head bolts, washers, and M6 hex nuts. Use the uppermost and lowermost
of the three drilled holes of the universal suspension bracket, refer to Fig. 15.
Pass the pressure probe through the cut-out of the universal suspension bracket.
Slowly and carefully lower the pressure probe into the observation well
with the pressure probe cable.
Pass the communication unit through the holes of the universal suspension
bracket until the communication unit is seated on the universal suspension
bracket, refer to Fig. 14.
Determine the current depth using a contact gauge and note the measured value.
Set the operating parameters, refer to Chapter 9.
Note
If protection against vandalism is required M6 threads are to be tapped into
the observation well instead of mounting the unit by means of hex nuts.

Example: 4" observation well
If required, you may fix the universal sus-
pension bracket reversed by 180° as well.
The socket head bolts will then be easily
accessible. In small diameter observation
wells, you may not be able to place the
optical reading head on the infrared inter-
face when establishing a communication
link. In such a case, position the reading
head in a maximum distance of 25 cm
above the infrared interface.
