
If the unit is installed on a surface that does not drain, place a pipe to channel the defrost water from the unit outlet to
the nearest drain. Figures 2.5 and 2.6 show several proposed systems to evacuate the water, depending on the support
system.

Make sure the water does not freeze in the drain pipe, since this could obstruct it. If there is a risk of the drain pipe
freezing, install a defrost heater in the pipe to ensure proper water flow during defrost. This heater can be activated from
the ecoGEO heat pump during defrost programs (DO6 connector).

If a siphon has to be installed, place it where it is not affected by freezing temperatures, as shown in Figures 2.5 and 2.6.
Refer to and follow local regulations for the assembly of the AU12 unit.
