I agree with the masses, I put the waste water hose in the sink to test it and attached it to the tap. That was over a metre and still worked. In the end, I have the drain at approx. 60cm, which works without any problems.

Width: 42.6cm Depth: 48.5cm
The maximum height for the dirty water hose should not exceed 80cm from the floor according to the instructions. Mine is 64cm and works perfectly.

The dimensions are: 485mm x 426mm x 280mm
You get tube material which is very long and can be cut to size.
unfortunately i can't find the length of the hoses but i think they are around 2 metres long
