Clearance for Daikin Heat Pump

Does anyone know the minimum distance that must be left between the side of a Daikin Altherma 3 M 4kW  (EDLA04EV3) and a wall? There seems to be no mention of this in the installation manual.

I think we were told 500mm by Octopus when they did our survey but I don't know if that's a figure they decided or if it came from Daikin.

I managed to find the installer manual. https://www.daikin-ce.com/content/dam/document-library/Installer-reference-guide/heat/air-to-water-heat-pump-low-temperature/EBLA04-08EV3.EBLA04-08E3V3.EDLA04-08EV3.EDLA04-08E3V3_Installer%20reference%20guide_4PEN685228-1B_English.pdf
