Important Notes
Safety note
ATEX (Atmosphère Explosible)
According to the European Directive 2014/34/EU the equipment must
not
be used in explosion-risk
areas.
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.
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.
Usage for the intended purpose
Use conductivity electrodes LRG 16-40, LRG 16-41, LRG 17-40 only for measuring the electrical con-
ductivity of liquid fluids.
For conductivity limiting or continuous boiler blowdown the conductivity electrodes LRG 16-40,
LRG 16-41, LRG 17-40 must only be used in conjunction with TDS controller LRR 1-40 and an
operating terminal & display unit type URB or SPECTOR
control
.
To guarantee a trouble-free operation observe the requirements made on water quality as specified in
the pertinent TRD and EN regulations.
Use the equipment only within its specified pressure and temperature limits.
Any other use is deemed as not being in compliance with the intended purpose. The user shall be
solely responsible for the associated risk. The manufacturer shall not be liable for any damage resulting
from improper usage.
