Flexit Albatros S10R, Installation And Maintenance Manual, Page: 60 / 72

4-1 Maintenance
The system should be inspected regularly. This must be performed by qualified operating personnel. The
inspection should be performed twice a year, preferably in the spring and autumn. If a water battery is used to
heat the air, check the system for water leaks. Listen for abnormal sounds and check for abnormal vibrations.
Check at regular intervals that the air intake is free of snow and leaves. The inspection and maintenance of fans,
recovery systems, air dampers, filters and heating batteries are essential to achieve optimal performance.
Component Action Interval
Rotor High impermeability filters are installed in the unit. It is not therefore usually
necessary to clean the rotor. If it should however be necessary, dust can be removed
with a soft brush. Further cleaning is possible by removing the rotor, spraying it
with a grease solvent and then blowing it clean from the opposite side. Distance
approximately 60 mm and max. pressure 8.0 bar. Check the drive belt and tighten
it if necessary. Check that all seals around the rotor are intact and tight.
Do not use detergent that is harmful to aluminium or the environment.
Where
required
Damper The air damper plates are suspended in plastic bearings and do not need lubrication.
The individual air damper plates are connected via an arm system that does not need
lubrication either. Check every year that the air damper is tight. If the air damper is
not properly tight, it can be corrected by adjusting the air damper motor or possibly
adjusting the arm tension. Check once
a year
Filter How frequently filters need replacing depends on the dust concentration in the air
that passes through the filters. It is very important to replace filters to ensure that
the system works properly. Filters must be replaced when the filter replacement lamp
on the control panel lights up. They must be replaced at least once a year. 1-2 times
a year
Electric battery Inspect the cables to the electric battery at least twice a year. Check for damaged
cables and components. Check tighten all terminal blocks for power supply to the
electric battery (elements, contactors, SSR) and other terminal blocks. Twice
a year /
Water battery The water battery will be exposed to dirt very rarely, as the system has filters fitted
with a high tightness class. If cleaning still is necessary, you can use compressed air,
which is blown in the opposite direction to the air flow, or a vacuum cleaner with a
soft nozzle. Cleaning must be done carefully to ensure that the battery's fins are not
damaged.
Fans The fans will be exposed to dirt very rarely, as the system has filters fitted with a high

required
Corrosion damage If there is corrosion damage to fins or pipes, this may indicate moisture or corrosive
air. The cause must be found and remedied. Where
