Installation on a soft ground
Draining condensate into a gravel bed
For installation on a ground, the condensate must be discharged via a downpipe into a gravel bed that is located in a
frost-free area.
The downpipe must go into a sufficiently large gravel bed so that the condensate can trickle away freely.
For more methods, refer to the INSTALLATION, OPERATION AND MAINTENANCE MANUAL.
To prevent the condensate from freezing, self-regulating heating cable(field supply) must be threaded into
the downpipe so that the condensate can discharge via the downpipe.
Installation on a solid ground
Guide the condensation pipe to a sewer, pump sump or soakaway.
For all installation types, ensure that any condensate that accumulates is discharged into a frost-free area.
To prevent the condensate from freezing, self-regulating heating cable(field supply) can be threaded into
the downpipe so that the condensate can discharge via the downpipe.
4.4 In cold climates
It is recommended that the unit be placed with the rear side against the wall.
Install a lateral canopy on top of the unit to prevent lateral snowfall in extreme weather conditions.
Install a high pedestal or wall mount the unit to keep a proper clearance (at least 100 mm) between the unit and snow.
① Canopy or alike
② Pedestal in case of installation on a ground
