6.2 Maintenance intervals
In order to maintain operational safety and hygienic demands the Nortec ME Control must be serviced
at regular intervals. The time interval for the complete system service is to be adapted to the operating
conditions. The hygiene status depends mainly on the quality of the humidifier water but also on the
adherence to the exchange intervals of the upstream air filter, the air velocity and the micro-biological
and chemical composition of the supply air. Therefore the service intervals must be determined for each
system separately.
The interval time for a complete system service is to be determined at commissioning. The default is
2000 hours of operation.
Depending on the encountered hygiene status when performing a complete system service the interval
time must be decreased or increased.
In any case the Nortec ME Control system should receive a complete service at least once annually.
Note: We recommend to perform a minor service between two complete system service.
The interval time for complete system service can be programmed on the control unit. To determine the
interval time for a complete system service the above described procedure can be used. As soon as
the maintenance time has elapsed, a maintenance message is displayed to draw your attention to the
pending service.
6.3 Maintenance guide
The Nortec ME unit will form part or your hot and cold water system and as such require you to undertake
certain duties with regards to local regulations and bylaws concerning the control of Legionella microbes
in water systems. Your water sampling / testing and disinfection regime must be based on results of a
site specific risk assessment.
If any further assistance is required or you are interested in a planned maintenance quote, please contact
your Nortec distributor .
Note: routine water sampling and testing is not included as part of a Nortec service contract.
Please note that the information given in the table below is only to act as a guide which shows the work
