I e-mailed as suggested above, got a prompt reply from Hoover (Gias), no pdf manual for the model I wanted, use form to respond with card details or telephone with card details. I telephoned (01204 556 111, between 08:30 and 17:00 Mon to Fri). They very kindly did not charge and are sending it directly to the relative that needs it. (Model was Hoover 1200 , AC 330 708 000 75.)
Thanks for pointing me in the right direction. Hope this helps others - I see there are many similar queries on this helpful site.
