Washer dryer - how does the dryer work ?

I have recently moved into a rented flat which has a built in washer/dryer. No instructions for it,however, and there are no clues anywhere as to what make it is.
I have worked out how to operate the washer, it has programme markings like A, B, F etc, and that works fine, but how do you operate the dryer separately, or can you only use it as part of a wash programme?
I think it may be an Italian machine, as there are instructions for putting the separate liquid drawer in the dispenser, and that is printed by an Italian company.
