Before installing the product, ensure that the sewage
system is at least 1 metre below where SCALA1
System is to be installed. The following requirements
must also be met:
• The room must have an outlet pipe that is
connected to the sewage system.
• The location must be dry and protected from rain.
• Flat wall, in horizontal position.
• Minimum distance from the ceiling: 50 cm.
We recommend installing a feed pump
with a maximum system pressure of 8 bar
if the distance between the rainwater tank
and SCALA1 System is too long.
