This presents the danger of severe injury. It is therefore essential not to
dismantle the electrode unless the boiler pressure is verified to be zero.

NRS 2-4 / NRS 2-5 to detect and monitor water or condensate levels.
The equipment must only be installed by qualified staff.
Qualified staff are those persons who – through adequate training in electrical
engineering, the use and application of safety equipment in accordance with
regulations concerning electrical safety systems, and first aid & accident
prevention – have achieved a recognised level of competence appropriate
to the installation and commissioning of this device.
