[C320-list] a/c winterizing

[Jamie Pett]

Dreading the prospect of winter, I am nevertheless facing the task of getting Bella Luna ready for the hard after our first amazing season with her. 
 
I have a copy of Carl's very nice article on winterizing the c-320.  It has been very helpful and I am working my way through winterizing - got the water system done last weekend.  The tips on draining the hw heater by releasing the pressure valve were very useful (amazed at how much water was still in there), but his paper does not say anything about winterizing a reverse cycle a/c heat unit.  
 
I thought I would simply close the thru-hull intake, open the strainer, and add pink stuff with the unit running until it comes out the outlet - can anyone add suggestions ? 
 
I also read somewhere that if you put the unit on fan only the compressor won't run, but don't know why that matters ?  Do I need to do anything else with the A/c compressor ? (or the Alder Barbour fridge?)
 
Also, on the engine - what is the best method for getting the pink stuff into the system  - my strainer for the engine is inverted, so I guess I can pull the intake hose and use it to pulll the antifreeze, but it seems awful short to try to suck pink stuff out of a gallon jug , and switching jugs mid-job seems difficult as well ? Any suggestions ?
