Inconsistency on the position of the outside air dampers (OADs) from one unit to the other. On some units, the OADs appear to be 100% open, while on others they are partially open when compared to similar types of units. For example:
• RTU-18 OADs are 100% open. At the time of walkthrough the outside temperature was approximately 66 deg. The OADs should not be 100% open at that temperature, it is too cold.
• RTU-16 – OADs are less open in comparison.
The OADs were observed to be 100% closed on the following units:
• RTU-# 4, RTU-7 and RTU-20
