MAINTENANCE AND UPKEEP

9.1 MAINTENANCE AND UPKEEP
!
! Personnel responsible for operating the control panel should read the documentation before
starting any operations and maintenance activities. In the absence of such personnel with the
necessary skills and competence, periodic inspections should be carried out by authorised VTS
service providers.
! 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.).
AIR FILTERS
•
Under standard operating conditions for air handling units, filters should be changed
approximately twice a year. The need to change the filter (in addition to visually visible
contamination) is also indicated by a drop in pressure:
o
Coarse 80% (EU4) - 150Pa,
o
ePM10 40% (EU5) - 250 Pa,
o
ePM2.5 65% (EU7) - 250 Pa,
o
ePM1
•
If the final differential pressure exceeds the design value, the filter must be replaced. The filters
are disposable components.
•
When changing the filter, the filtration section should also be cleaned - either with a hoover or
by dry cleaning.
•
When ordering a new filter set from an authorised VTS office, specify the type of filter, the
filtration class, the size of the air handling unit and, if necessary, the size of the filter, as specified
on the technical data sheet or in the "AIR FILTERS" section.
