Well I thought about this for a few, If I'm off hear or sound off then someone let me know but:
Water in the AC system is from the moisture in the air that is being blown across the condenser condensing on the fins, then becoming water, dripping off the fins and draining out the hose in the bottom. So everything in the plastic box that contains the condenser should by design be allowed to get wet.
Clear as Mud?
