If the above water quality parameter values cannot be met, WEGER cannot guarantee proper
operation of the unit.
Depending on the water hardness and the impact of a unit failure, it might be necessary to
treat the water for humidification:

7.6. Silencer
The silencer baffles are maintenance-free. During major overhauls, check the baffles for dust
and clean them with a vacuum cleaner, if necessary.
The surfaces of the bafflers must not be damaged.
7.7. Multi-leaf dampers
According to Standard H6020, extra tight dampers for room classes H1, H2 and H3 must be
equipped with two end position switches.
Air control dampers are generally maintenance-free. If the leaves are stiff, check them for
proper fit. The leaves must not be stressed. During major overhauls, clean the leaves with
water or compressed air. Should the leaves be stiff, apply a little silicon spray to the lateral leaf
bearings.
7.8. Weather guards
Check the weather guards once a month for dirt and damage. Remove leaves, paper, etc. that
might obstruct air intake.
