Question about Intex Krystal Clear sand filter system

Hello
L×W×H = 55 cm × 50 cm × 61 cm without connection hose.
If the connection hose also has to be in the box, I think that at B at least 20 cm must be added to avoid kinking the hose. If the hose is led out of the box by means of a hole cut-out, 50 cm is sufficient. If it is only to supply the system in winter, the hose is also dismantled and the 50 cm is also sufficient.
I hope that I have been able to help.
Kind regards
