Condensate drain
The condensate drain network must be sized appropriately
(minimum inner pipe diameter: 14 mm) and the pipeline
positioned so that it maintains a consistent slope along the
line (never less than 1%). The drain pipe connects directly
to the drain pan installed at the bottom on the side panel
under the hydraulic connections.
-
If possible, make the condensate liquid flow directly
onto a gutter or into a "white water" drain.
- If the liquid is discharged into a sewer, we recommend
that you install a trap-vent to prevent bad odours from
rising back up into the building. The curve of the trap
must be lower than the condensate tray.
- If you need to drain the condensate into a container, it
must remain open and the pipe must not be immersed
in water to prevent adhesion and back-pressure that
would obstruct free flow.
- If the drain pipe has to overcome a gap in height
due to its particular installation which would obstruct
condensate flow, remember to install a pump:
These pumps are commonly available on the market.
However, it is advisable that after installing the pump you
check proper flow of the condensate liquid, pouring it in
very slowly (about 1/2 l of water in about 5-10 minutes) into
the drain pan.
Connect the drain connection of the drain pan that collects
the condensate fluid to a hose and tighten it properly. Make sure the drip-guard extension is present and that it
has been properly installed.

Pay attention to the tilt of the condensate drain pipe when
it channels condensate outside the premises as shown in the figure.
