Ensure that the water seal connected to the
domestic wastewater system is always filled
with water.
Ensure that the hose end terminates at least
60 mm below the water level. This will pre-
vent the santos from drawing in air.
Do not connect the condensate drain direct-
ly to the sewage drain system (for example
flowing freely into funnel with condensation
drain at the sewage system)
3.7 Commissioning the santos
The santos can be put into operation after instal-
lation.
It is possible to carry out the commissioning proce-
dures utilising P menus on the digital control panel.
These P menus allow various settings (in particular
for ventilation control) to be selected for the san-
tos. An overview of the available P menus is given
below:
