6.6 Health and safety requirements
In accordance with local regulations, users must take water samples for Legionella analysis. Samples
should be taken from the same places as described in chapter 6.7 – Routine water sampling and testing,
and the analysis carried out by an accredited laboratory which is part of an appropriately certified Legi-
onella testing scheme. In the event that the Legionella content exceeds 10 2 cfu/l, the humidifier should
be switched off and specialist advice sought regarding its disinfection.
1. If biofilm (a slimy or gel-like deposit when wet, which might be dry and crisp in a dry system) is found
during any inspection of the humidifier or water system, the humidifier MUST be switched off and
not put back into operation until the system has been taken apart, scrubbed and thoroughly cleaned
with a suitable biocide with biofilm penetrating qualities such as 50 ppm chlorine dioxide solution.
This work should only be carried out by fully trained specialist organisations or individuals.
2. The control unit of the Nortec ME Control must be left powered on to allow automatic flushing
and cleaning cycles to occur. If the control unit Nortec ME Control is powered off for prolonged
periods, water stagnation might occur and contamination result, so the system, including any stor-
age tanks or vessels should be drained and left dry. Before putting the system back into service, the
water pipework supplying the Nortec ME Control should be purged carefully, avoiding the creation
of aerosols by splashing, and a water sample should be taken to ensure cleanliness. In the event
that the humidifier pipework contains any residual water or has remained damp, and the temperature
exceeded 20 °C (68°F), the Nortec ME Control should be disinfected using an appropriate solution.
Contact your Nortec representative for advice on water sampling and analysis, disinfection of systems,
service and maintenance.
