The condensate drainage system is designed for normal operation in
premises with air temperatures above 0 °C!
If the expected ambient air temperatures are below 0 °C the
condensate drainage system must be equipped with heat insulation and
pre-heating facilities.
WARNING
In case of several units mounting connect each unit to an individual U-trap.
Direct condensate drainage with no connection to the drain system is not allowed.
