4.2 Cleaning and Inspection

4.2.1 General

Access for cleaning must be ensured when planning and during
the installation of the air handling unit. This can, for example,
include the set-up of the unit, and pipe and cable routing.
Clean the interior of the air handling unit if needed. Inspection
of the air handling unit should be performed when you change
filters or at least twice a year.

4.2.2 Filter spaces

The most appropriate time to clean the unit is when you change
the filters.

4.2.3 Heat exchangers

Check whether cleaning is necessary at least twice a year. Clean-
ing can be done from the filter space.
Always clean against the regular direction of airflow.
Cleaning must only be done by blowing with compressed air,
vacuum cleaning with a soft nozzle or wet cleaning with water
and/or solvent. Before you begin cleaning, cover adjacent func-
tional sections to protect them.
If cleaning solvent is used, do not use solvent that will corrode
aluminium or copper. Swegon's cleaning agent is recommended.
This cleaning agent is sold by Swegon Service.
Inspect the drain to make sure that it isn't clogged. The by-pass
and shut-off dampers do not require maintenance.

4.2.4 Fans and fan spaces

Inspect and, if needed, clean the fan impellers to remove dirt
deposits.
Check the impeller to make sure that it is not out of balance.
Check the bearings for noise.
Vacuum clean the fan motor or brush its surfaces. It can also be
cleaned by carefully wiping it with a damp cloth and dishwash-
ing detergent.
Clean the fan space, if needed.
