I have FSM for a later model Legacy. It say to run a vacuum pump for several minute to get the water vapor out of the system. There is a procedure for this.
What happens if I run the ac system and there is water inside it?

But just moisture from the outside air.
I would find the leak before pulling a vacuum on the system.
If you have a pretty bad leak, ( all the refrigerant is gone), you will pull more moisture into the system by pulling a vacuum.
The low side safety should not allow you to get mush moisture in the system because before the system gets low enough for a negative lo side, the compressor clutch will not ingage. ( the purpose of the lo side safety)
