5.1 Important notes on maintenance
Qualification of personnel
All maintenance work must be carried out only by
well qualified and trained personnel authorised by
the owner. It is the owner’s responsibility to verify proper qualification of the personnel.
General notes
The instructions and details for maintenance work must be followed and upheld. Only carry out the
maintenance work described in this documentation.
The Nortec ME Direct Feed must be maintained in the prescribed intervals, the cleaning work must be
carried out correctly.
Only use original spare parts from your Nortec representative to replace defective parts or parts which
have elapsed their lifetime.
Safety and hygiene
Some maintenance work requires removal of the unit cover. Please note the following:
DANGER!
Danger of electric hazard!
Before carrying out any maintenance work take the Nortec ME Direct Feed out of operation as
described in chapter 4.6 – Decommissioning the system and secure the system against inadvert-
ent power-up. In addition take AHU out of operation as described in the operations instructions of the
AHU and secure the AHU against inadvertent power-up.
CAUTION!
The electronic components inside the optional Nortec control unit are very sensitive to electrostatic
discharge.
Prevention: Before carrying out any maintenance work to the electrical or electronic equipment of
the control unit, appropriate measures must be taken to protect the respective components against
damage caused by electrostatic discharge (ESD protection).
DANGER!
Health risk by inadequate maintenance!
Inadequately operated and/or poorly maintained adiabatic humidification/cooling systems may
endanger health. When inadequately operated and/or poorly maintained, micro-organisms
(including the bacterium which causes Legionnaire’s disease) may grow in the water system
and in the area of the humidification unit and may affect the air in the AHU/air duct.
Prevention: the adiabatic air humidification /air cooling system Nortec ME must be correctly operated
as described in chapter 4 – Operation, and must be correctly maintained and cleaned in the prescribed
intervals as described in chapter 5 – Maintenance.
