The [https://www.manualslib.com/manual/1202800/Amana-Aac051sra.html?page=12#manual|user manual] only mentions the one drain plug so this is where the water (condensate) should flow out from, usually into a condensate drain pipe which is connected to where the hole is if you have high humidity problems.
You stated that there was standing water but does the water actually flow out?
The installation diagram for the unit show that it should have a [https://www.manualslib.com/manual/1202800/Amana-Aac051sra.html?page=11#manual|half bubble slope] from the front to the back of the unit to allow the water to drain out. This is for a window installation but I assume it should be the same for a wall mount.
It also mentions on p.16
ODORS IN COOLING :
Mold, mildew, or algae formation on wet surfaces To reduce growth use algacide tablet in the unit base pan or remove drain plug or add a condensate drain. Have your unit thoroughly cleaned

Hi @tronke ,
Has the unit got a spirit level "half bubble slope" from front to back as described in the manual I linked to ensure adequate condensate drainage?
