7.1. Housing
Once the unit is installed (and periodically) check whether there are no foreign objects, debris or tools inside the unit.
Inner and outer surfaces shall be cleaned with a damp cloth or a vacuum cleaner. Also check the housing for mechanical
damage or signs of corrosion which could affect normal operation of the unit. As building stability may change over time
(e.g., settling of foundations), regular unit horizontality checks using a level gauge are recommended; levelling shall be per-
formed if needed. Deviations must not exceed 0.3mm for 1m in the longitudinal direction and 0.5m for 1m in the transverse
direction; otherwise, sections may warp and loosen their connections. Check the unit doors for tightness and if all gaskets
or sealant joints are intact. Replace gaskets and reseal joints, if needed. Inspect air collection/exhaust dampers and grilles.
Remove accumulated dirt; check dampers for proper opening and tight closing. Check operation of electric actuators and
wiring contacts of dampers. Check whether condensate is freely removed from drip trays; check siphons for proper opera-
tion; check drainage pipeline components for damage/blockage. If the unit is equipped with drip trays, regularly clean any
dirt from drip trays.
