2.2 Health and hygiene
DANGER!
The Nortec ML System must be installed, operated and maintained in accordance with this manual.
Failure to do so could result in contamination that might cause Legionnaires’ disease, which can be
fatal.
DANGER!
To prevent water stagnation and microbial contamination, the systems power supply should be left
switched on. If the system is switched off for more than 48 hours, the pipework and system must be
disinfected as per the instructions, and a full risk assessment must be undertaken to ensure safe
operation.
Health risks
Please observe the local health and safety codes, standards and technical guidance on the control of
Legionella in water systems.
The user is responsible for ensuring that the water system complies with local regulations, bye-laws and
guidelines (such as the HSE ACoP L8, VDI 6022, ISO 22000, HACCP or equivalent). If inadequately
maintained, water systems, of which any humidier is a part, can support the growth of microorganisms,
including the bacterium that causes Legionnaires’ disease.
Nortec ML systems, products and components are produced according to the ISO 22000 standards,
which means that we have considered all aspects of this equipment to reduce the risk of Legionnaires’
disease and other similar conditions. However, the user is responsible for ensuring that the installation,
operation and maintenance work on the equipment is performed in a manner ensuring that the system
stays clean.
Any risks or hazards relating to the system, including during installation and maintenance, should be
identied by a competent health and safety representative who is responsible for introducing effective
control measures.
Water monitoring
The quality of water being used in the Nortec ML Humidication System should be checked prior to
system commissioning and comply with the guidelines in the high pressure pump manual.
The Nortec ML Humidication System must be monitored for hygiene as part of the maintenance pro-
gram. Please refer to the maintenance section for further guidance.
