No definite information on the luxair dot com site. Best bet is to go to their site and ask them the question.
All the hoods I've worked on (never worked on luxair) have had earth to them and the motors have been earthed to the hood.
I've just phoned them (emailed them as well for a written reply!), and they've assured me that it's perfectly safe. Apparently the Italians have their own regulations for covering this subject, but I queried if what was OK for the Italians was it OK for us! Got a definite YES -- quite safe.
I must say I'd rather have a stronger reassurance than that!!
Thanks for your help and advice. :
