Ken,
On my older Gaggia Factory I would drain the boiler completely while the machine was still a little warm so that all moisture would evaporate. Doing this will require you to pump the lever a few times with the machine tilted to direct the water into the hole in the group head so that it drains back into the boiler, or you could drop the piston and lube the seals while you are at it. Either way, you'll get all the water out. There is no harm in it being left completely empty. After all, they are shipped that way.
When putting back in use, just flush the boiler a few times before emptying completely and topping off with the water you plan on using.
