Translation:Let's remember that he is not a teacher.
I would say that it's too different. "Pamiętajmy" means "let's not forget", or "let's keep in mind". However, "recall" refers to information that was forgotten, or at least inaccessible for some time. In Polish that would be "Przypomnijmy sobie, że on nie jest nauczycielem".
Also, I have some doubts about it, stylistically. "Recall" doesn't sound so great with a conjunction. "Let's remind ourselves that" would fit better.
