CAUTION
Risk of fire and explosion due to foreign objects on the electric heating coil
„
Before commissioning, check the electric heating coil for foreign objects.
ATTENTION
Hygienic and toxological concerns may arise during 100% recirculation air operation due to
the contamination of the waste air with pollutant gases. A minimum outdoor air volume flow
must therefore be ensured during recirculation air operation.
ATTENTION
Check seals before commissioning and apply seals when fans are running.
Before starting up the system, check:
„
Mechanical function of the multi-leaf dampers.
„
Tight fit of all installed filters.
NOTE
AL-KO THERM generally recommends the replacement of all installed filters after a short
period of operation of the AC unit to remove any dirt that may have entered the filters during
the installation phase and after commissioning (see chapter "7.4 Replacing components" on
page 126).
Use only original spare parts.
