Note:
There should be at least 50 mm (2") free space between the sensitive part of the water
probe and the tank shell (or any other large metal part in the tank, i.e. stilling well).

water & temperature probe
Installation preparations:
Before installation can be started it is recommended
to verify the installation height and probe length.
Measure the distance (refer to figure 5):
roof nozzle (well nozzle) – tank bottom.
Note:
If the commissioning takes place directly
after installation, also measure the product
level and the amount of water in the tank at
the place of the probe.
These measurements will be used with the
commissioning.
 Unroll the probe at a suitable place;
 Make sure the probe is completely
stretched;
 Measure along the probe, starting from
the bottom side and mark the measured
nozzle height at the threaded top side
(adjusting pipe).
