Risk of damage to the unit!
•
When entering CAIR units, ensure that no loads are applied on the floor
panels.
•
For all installation work, take appropriate measures to ensure that the load
is evenly distributed across the bottom profiles.
The specified maintenance intervals apply to air conditions with normal levels of con-
tamination. The maintenance intervals must be reduced according to the level of air
contamination.
Notice!
Carry out additional cleaning if treated air contains oil. Sealant material is oil-proof
only for a limited time. When using disinfectants, only use those according to
DGHM list, DVG or VAH certification.
