4.6 Flexible connection
EN
Check the flexible connection at least 1x per year.
4.7 Warm water, steam, cooler battery [9]
Care should be taken when cleaning Cu/Al batteries. If the battery is dirty in the air direction, it
can be blown clean in the opposite direction using compressed air or water. Ensure that the fins
do not deform during cleaning. You should also prevent dust from entering the air handling unit
and air duct.
4.8 Maintenance of gas-fired heat sources
See the installation and maintenance instructions supplied for the adjustment and maintenance of
gas-fired heat sources. Warning: never switch off the electrical voltage until the air heater has
cooled down completely.
4.9 Drip catcher [8]
Maintenance: Check the drip catcher for contamination, damage and corrosion. Clean the drip
catcher with compressed air, water steam or detergents containing soap. Check the water outlet
and siphon/S-trap.
4.10 Sound attenuator
If a sound attenuator is used, the wings cannot usually be removed from the attenuator section.
Never clean the soft attenuating material with water. It is preferable to use a vacuum cleaner
and/or a soft brush.
4.11 Heat recovery
Cross-flow heat exchanger
Under normal use of the air handling unit, the cross-flow heat exchanger would not be expected
to become contaminated. If the air handling unit is used in extreme conditions, such as in welding
areas, paint spraying locations, kitchens and the like, contamination may occur. Cleaning can be
completed as follows: dust and other particles can be easily removed using a brush. Take care if
using compressed air. Make sure that the element pack is not damaged. Greasy deposits can usu-
ally be removed with warm water. If necessary, suitable detergents may be used. It is recom-
mended that any gravity shutters and servo motors be cleaned annually.
Rotating heat exchanger
Check that the wheel is rotating in the correct direction. Rotate the heat exchanger periodically
during the summer months to utilize the exchanger's self-cleaning capacity. A dirty surface may
have a negative impact on the exchanger's performance.
