A condensate drain pump option is available (see technical specifications), provided that the humidifier option has not been requested.
If the humidifier option is selected, the discharge must not drain into the unit's drain pan. To have a single discharge for both, connect
the humidifier drain downstream of the unit's drain pan.
Warning: the condensates from the humidifier can reach 100 °C.
