What resin for RO4040 hard water area

[ManOfKent]

So quick question - I'm filtering water using a RO4040 system and Vyair are recommending that I use SOFT water resin for my DI vessel even though I live in a hard water area. Apparently this is what's needed if using a 4040 system?! Seems a bit odd to me... does anyone else do this or know the reason why?

Sounds dodgy to me, my tap TDS is anything up to 400ppm and I only use Tulsion mixed bed resin

Vyair don't have the best reputation I'd be buying elsewhere, the guy either hasn't got a clue or they need to offload some stock that has been sitting collecting dust and he could be trying to sell you water softener resin
