If your Daikin Nexura outdoor unit emits water or steam, here are some of the reasons this might be the case:

In HEAT or RADIANT operation

The frost on the outdoor unit melts into water or steam when the air conditioner is in defrost operation.

In COOL or DRY operation

Moisture in the air condenses into water on the cool surface of outdoor unit piping and drips.
