6.5.2. Condensate drainage

The units are supplied with 2 drains (one for each circuit). For added security it has to connect two
drains to the condensate discharge pipe. This connection must be made through a pipe of 22 mm
of inner diameter and a fl ange for secure fi xation.
Drainage system
• To ensure the removal of draining condensate from the tray a siphon must be installed with
pressure head difference in mmWG greater than the pressure provided by the fan.
• The horizontal sections should have a minimum slope of 2%.
