Caution
·
If used in connection with steam humidifiers, the distance to the humidifier must be
a minimum of 3 m. If permitted by the installation, the distance should be as great
as possible, but no more than 10 m
· The sensing elements in the immersion rod are susceptible to impact and shock.
Any impact or shock should therefore be avoided.
Mounting instructions are enclosed in the package.
Disposal
The device is considered electrical and electronic equipment for disposal in terms of the
applicable European Directive and may not be disposed of as domestic garbage.
