Un bon manuel d’utilisation

Les règles imposent au revendeur l'obligation de fournir à l'acheteur, avec des marchandises, le manuel d’utilisation Bradford White D-38T-155.

Qu'est ce que le manuel d’utilisation?

Le mot vient du latin "Instructio", à savoir organiser. Ainsi, le manuel d’utilisation Bradford White D-38T-155 décrit les étapes de la procédure.
