Important Notes
Usage for the intended purpose
Use blowdown controller LRR 1-40 only in conjunction with conductivity electrode LRG 16-40,
LRG 16-41, LRG 17-40 and an operating & display unit type URB or SPECTOR
control
for detecting and
monitoring electrical conductivity in liquids (TDS control).
Note that the application of the control unit LRR 1-40 for conductivity limiting purposes or continuous
boiler blowdown is only permissible if it is used in conjunction with the conductivity electrode
LRG 16-40 / LRG 16-41 / LRG 17-40 and an operating & display unit type URB or SPECTOR
control
.
To guarantee a trouble-free operation observe the requirements made on water as specified in the
pertinent TRD and EN regulations.
Any type of use differing from the usage described above must be considered as improper. The result-

for any damage resulting from improper usage.
Safety note
The equipment must only be installed and commissioned by qualified and competent staff.
Retrofitting and maintenance work must only be performed by qualified staff who – through adequate
training – have achieved a recognised level of competence.
ATEX (Atmosphère Explosible)
According the the European Directive 2014/34/EU the equipment must
not
be used in potentially
explosive areas.
Attention
The name plate specifies the technical features of the equipment. Note that any piece of
equipment without its specific name plate must neither be commissioned nor operated.
