7. Commissioning and maintenance
Maintenance intervals for air handling units
Air handling units are machines that require regular servicing. The specified maintenance
intervals are approximate intervals based on air with an average contamination load, following
VDI 6022. For highly contaminated air, the maintenance intervals must be shortened
accordingly. Regular maintenance does not release the owner from his responsibility of regular
testing of the unit and inspection of the unit for damage.
Cleaning and maintenance
•
The individual components of the air handling units must be accessible for cleaning, etc.
from the inlet and outlet side. In units with a head clearance of < 1.6 m, it must be
possible to remove these components safely (see DIN 1946).
•
Remove visible dirt with an industrial vacuum cleaner (dry cleaning).
•
Remove other dirt with a damp cloth:
•
If necessary, use grease- or oil-dissolving detergents (concentrated neutral detergent with
pH between 8 and 9).
•
Treat galvanized parts with preservation spray.
•
Regularly lubricate moving parts such as door levers and hinges with a lubrication spray.
•
Regularly treat seals on doors, etc. with talcum powder or Vaseline.
•
Repair any damage to the coating, including areas that show signs of corrosion, with
repair paint.
All parts of the wet section of the air cooler should be cleaned.
Air-conditioning units must only be operated according to applicable capacity and
performance specifications.
Clean the unit thoroughly to remove all construction dust and other dirt.
Prior to shipping, each unit is carefully inspected at our factory. It is however necessary to
check the following again prior to commissioning:
- Are all pressure side access doors equipped with door catches?
- Are the multi-leaf dampers in their operating position?
Can the fan and/or the motor be moved easily by hand (unobstructed rotation)?
