Preparations

Installation site
The appliance is designed to be permanently wall-mount-
ed to a solid surface. Ensure the wall offers adequate load
bearing capacity.
There should be a suitable drain near the appliance to
drain off the expansion water.
Always install the appliance vertically in a room free from
the risk of frost and near the draw-off point.
It may not be fitted in a corner since the screws for fixing
the appliance to the wall must remain accessible.
