Preventive maintenance
Introduction
The units need preventive maintenance with specific intervals to avoid breakdown or
inefficient operation. It is important to notice that interval between maintenance can
vary depending on the specific environment.

use a …
to …
vacuum cleaner or compressed air
carefully clean the unit
soft bristle brush
remove dirt that the vacuum cleaner or
the compressed air could not remove
screwdriver or torx
tighten loose screws to get into the unit
Interval
Dantherm Air Handling recommend that intervals between preventive maintenance do
not exceed 6 months. It is also our recommendation that the site and unit is examined
closely during the first preventive maintenance to determine whether the interval is too
long. We recommend that preventive maintenance visits are planned to occur before
and after the hot seasons. This will ensure best performance during both hot and cold
seasons.
