MAINTENANCE
13.1
Routine maintenance
This unit must be maintained by qualified technicians. Before beginning any work on the system, the personnel shall assure that
all security precautions have been taken.
Neglecting unit maintenance could degrade all parts of the units (coils, compressors, frames, pipes, etc.) with negative effect on
performances and functionality.
There are two different levels of maintenance, which can be chosen according to the type of application (critical/noncritical) or to
the installation environment (highly aggressive).
Examples of critical applications are process cooling, data centres, etc.
Highly Aggressive Environments can be defined as the follows:
•
Industrial environment (with possible concentration of fumes result of combustion and chemical process).
•
Coastal environment.
•
Highly polluted urban environment.
•
Rural environment close to of animal excrement and fertilizers, and high concentration of exhaust gas from diesel generators.
•
Desert areas with risk of sandstorms.
•
Combinations of the above.
•
Unit exposed to a highly aggressive environment can face corrosion in a shorter time than ones installed on a standard
environment. Corrosion causes a rapid rusting of the frame core, consequently, decreases unit structure lifetime. To avoid
that, it is necessary to wash periodically the frame surfaces with water and suitable detergents.
•
In case of part of unit frame paint came off, it is important to stop its progressive deterioration by repainting the exposed
parts using proper products. Please contact factory to get the required products specifications.
•
In case of just salt deposits are present, it is enough to rinse the parts with fresh water.
