1.0 MAINTENANCE
1.1 IMPORTANT NOTES ON MAINTENANCE
Qualification of personnel
All maintenance work must be carried out only by well qualified and trained
personnel authorized by the owner. It is the owner’s responsibility to verify proper
qualification of the personnel.
General note
The instructions and details for maintenance work must be followed and upheld.
Only the maintenance work described in this documentation may be carried out.
Only use original Nortec spare parts to replace faulty parts.
Safety
Before carrying out any maintenance work take the Nortec MH out of operation as
described in this manual and secure the unit against inadvertent power-up. In
addition, take the ventilation system out of operation as described in the operation
instructions of the ventilation system and secure the ventilation system against
inadvertent power-up.
The Nortec MH 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 and the
humidification boxes (and the mist eliminator) of the Nortec MH
and may affect the air passing through the humidifier.
1.2 MAINTENANCE INTERVALS
In order to maintain operational safety the Nortec MH 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.
