Important Notes
Danger
When loosening the electrode steam or hot water might escape.
This presents the danger of severe scalding. It is therefore essential not to remove or
install the electrode unless the boiler pressure is verified to be zero.
The electrode is hot during operation. This presents the danger of severe burns to hands
and arms. Installation and maintenance work should only be carried out when the system
is cold.
Usage for the intended purpose
Use conductivity electrodes LRG 6-40/LRG 7-40 only for measuring the electrical conductivity of
liquid fluids.
For conductivity limiting or continuous boiler blowdown the conductivity electrodes LRG 6-40/
LRG 7-40 must only be used in conjunction with TDS controller LRR -40 and an operating terminal &
display unit type URB or SPECTORcontrol.
To guarantee a trouble-free operation observe the requirements made on water quality as specified in
the pertinent TRD and EN regulations.
Safety note
The equipment must only be installed and commissioned by qualified staff.
Maintenance and service work must only be performed by adequately trained persons who have
a recognized level of competence.
