Water in Alde Flow Tank in new-to-me 2021 Tab 400

in Heating/Plumbing & Winterizing
On day 5 of ownership of my 2021 400, I took advantage of temperature in the mid 40s to check the Alde flow tank.  I opened both yellow flappers and the hot water line produced a small stream of pure water which added up to several cups in a half hour of flow.  I am assuming the slow flow is a result of ice melting.
The previous owner winterized by siphoning antifreeze through the Nautilus but did not use compressed air blow out.  The Nautilus is still in the winterized position.  No water came out of the cold water flapper valve.
I am inclined to leave the flapper valves open so any ice can continue to drain as it melts -  unless anyone advises otherwise.  Are there any other actions I should take now other than worry about the condition fo the Flow Tank?

Thoughts on my now running the Alde to melt any additional ice and have it drain?

I assume running the Alde without water in the tank is a safe practice.
Thank you.

    If you think excessive water was left in the Alde and Flow tanks, then I would heat the cabin with the Alde.   Place a pan under the yellow flapper drains (Alde Safety/Relief drains) and keep the drains open.  Watch the area under the bench for any leaks, although, they may not appear until temperatures rise and you are able to safely fill the Alde tank.

    Yes, you can run the Alde to heat the cabin without having water in the Alde tank.

    The stream stopped after 2 or 3 cups.  Hopefully there was just a small residual amount left and it is not that there is more  which is still ice.  I will heat the trailer with the Alde and see if more flows. Thank you.

     Try opening the hot water tap/faucet to help drain the Alde and Flo tanks.  (This will not work if the water lines are filled with antifreeze.  
    The Alde and Flo tanks are stainless steel cylinders are I’d left with a partial bit of water, should not damage the tanks, as the water freezing has room to expand up into the tank.  The tanks are also vented at the top, so air pressure changes can release out.

    @Denny - if the Plumbing lines are filled with antifreeze and the Alde is bypassed via the Nautilus settings, I am not sure if opening the hot tap will have a benefit.  What do you think?

    Sharon, yes, if the lines have antifreeze in them, then opening the faucet isn’t going to do anything.  Changed my original post, thanks for pointing this out.  I was thinking, using the hot water tap to vent the Alde hot water tank, but it already has its own vent.
