Airspa bath

[Bumblebee333]

Don't know if I am posting in the right place.

I have been given a bath by a friend who bought them really cheap at a bathroom showroom that was closing down.

She has had them a while and after selecting the one she wanted has just kept the other two in her garage.

Anyway this bath is a renaissance alveus air spa bath. The problem is that I have the bath but I don't have any of the parts to make the bath do the airspa bit.

can anybody help me work out what I need?

I contacted renaissance and they said go back to the showroom butbi can't because it is no longer there.

Does anyone have this bath or similar that can tell me what I need to make it work?

Thanks
