The pump outlet pipe should discharge to a suitable internal foul water discharge
point such as an internal soil and vent stack, internal kitchen, bathroom waste
pipe, or washing machine waste pipe. A suitable permanent connection to the foul
waste pipe should be used.

7.6.2 External connections
If an externally condensate drainage pipe is used, following measures should be
made to prevent freezing:
▪ The pipe should be run internally as far as possible before going to the outside.
The pipe diameter should be increased to a minimum inner diameter of 30 mm
(typically outer diameter of 32 mm) before it goes through the wall.
▪ The external run should be kept as short as possible, taking the most vertical
route possible to the discharge point. Take into account that there are no
horizontal sections in which condensate might collect.
▪ The external pipe should be insulated. Use a suitable waterproof and weather
proof insulation ("Class O" pipe insulation is suitable for this purpose).
▪ The use of fittings and elbows should be kept to a minimum. Any internal burrs
should be removed so that the internal pipe section is as smooth as possible.
