10 MAINTENANCE
10.1 MAINTENANCE
!
! The basic technical data of the air handling unit, such as the type, parameters and dimensions
of the most essential components (filters, heat exchangers, fans, electric motors), can be found
in the technical data sheet that is supplied with each unit.
! All maintenance work on air handling units should be carried out with the unit switched off. To
ensure safe operation of the unit, the service switch, which cuts off the power supply to the motor
during maintenance work, must be installed outside the fan section. Disconnection of the power
supply circuit by the service switch must take place in a de-energised state. The service switch
should be located near the inspection panels of the fan section.
! Thorough and regular maintenance as well as technical inspections of air-handling units and their
components are essential in order to identify faults at an early stage - before more serious failures
and damage occurs.
! This documentation only covers general guidelines for inspection intervals to ensure fault-free
operation of the units under the various possible external operating conditions. The technical
inspection intervals must be adapted to the local conditions (level of contamination, number of
start-up cycles, loads, etc.).

!
! REMEMBER THE ENTRIES IN THE DEVICE CARD!
! The F-gas regulation requires refrigeration system operators to keep records of legally mandated
leakage checks. The records must be kept by the system operator and the staff or company
carrying out the inspections for at least five years.
! Of particular importance are the case records in relation to leakage checks. They must include
the following information:
•
All quantities of F-gases added during activities such as installation, maintenance, servicing
or spill response,
•
Name and address of the recycling or reclamation facility (including certificate number, if
applicable) if recycled or reclaimed F-gases are used,
•
All quantities removed and remediated,
•
The company that worked on the equipment (with certificate number, if applicable),
•
Leakage control results (retesting),
•
In case of system decommissioning: measures taken to recover and dispose of fluorinated
greenhouse gases.
