The NORTEC MH Series must be maintained in the prescribed intervals, the cleaning work
must be carried out correctly, and the humidification boxes and the mist eliminator boxes
must be replaced after their prescribed lifetime has elapsed.
Warning! If the unit is insufficiently maintained germs which can cause illness, may grow in the
water tub, the humidification boxes, and the mist eliminator of the NORTEC MH Series and may
affect the air passing through the humidifier.
Maintenance Intervals
In order to maintain operational safety the NORTEC MH Series must be maintained in regular
intervals. The time interval for the maintenance 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 maintenance intervals
must be determined for each system separately.
The first maintenance must be carried out after 800 operating hours. Depending on the
encountered hygiene status during the first maintenance the interval time must be decreased
or increased.
In any case, the NORTEC MH Series is to be maintained at least twice annually.
On units equipped with an MH control unit (MHTC flow, and MHTC reflow) the maintenance
interval can be programmed. As soon as the maintenance time has elapsed, a maintenance
message is displayed to draw your attention to the pending maintenance. To determine the
maintenance interval time, the above described procedure can be used.
