It is in Frost Prevention mode - the appliance will start up again automatically once finished.

    LT means "Low Tempature" which will allow it to defrost as it is running.

PAC L90 LT thermostat not working, unit icing over

No that would be either a dirty filter/coil ir low refridgerant if it's freezing in cooling mode.

Clean/replace the filter, clean the coil and if it keeps doing it, have a technician who is EPA certified for servicing systems with refridgerant to look at it/add refridgerant.

It's actually "Ft", which means "Full Tank".  The instruction manual says to drain the internal safety tank through the drain hoses.
To drain the tank, open the cover on the rear of the appliance. Pull out the 2 drain hoses, take off the caps, and let all the residual water flow out.  When all the water has been drained, place the caps back on the hoses and put the hoses back inside.
It also says you need to clean the filters and let them dry thoroughly before putting them back.
This is also the procedure for "End of Season Operations."
Hope this helps!

Hoses for proper connection should have been included with your purchase. Without the hoses the set-up can not be done satisfactory. One is for fresh air supply and the other is the hot air exit hose. These are normally vented out a window. Check with the dealer where you perchased the unit from. If from a private individual contact them.
