Use level electrode type NRG 16-41.1, NRG 17-41.1 or NRG 19-41.1 only in conjunction with control
equipment
NRS 1-40.1
as high-water level limiter (high-level alarm).
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
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.
If the internal ceramic insulation breaks, hot steam can escape through the lateral vent
hole on the electrode body. This presents the risk of severe scalding. Do not stay near
the electrode during operation.
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.
Attention
The name plate indicates the technical specification of the equipment.
Do not commission or operate equipment without a name plate.
