It's typical that the AC unit condensate line include a trap at the unit but none-the-less the line should not terminate in a sanitary line.
In fact, it is common that there are two lines coming out of the AC unit. The normal condensate line and an overflow line.
Remember that those AC traps do not see condensate all year round and are subject to drying out. They typically don't get equipped with trap primers, so legal or not, you must ensure that the trap always have a water seal.
EDIT: Don't lose sight of the fact that those condensate traps are not approved plumbing traps.
