Winterizing a dead Cruisair..... I know, sounds odd

I have a Crusair 7000 BTU that is currently disconnected because of an electrical issue with it. I have a second 12,000 BTU unit that has been heating/cooling the cabin quite effectively so I haven't been motivated to repair it. Both units share the same pump and plumbing.

I still have to winterize the thing and connecting it back in to power isn't going to work. Do I need to have the unit working, or is there a way to blow air through it or something else?

Thoughts?
 
If the boat is blocked up out of the water:
Back flush anti freeze through the system from the discharge on the side of the boat until the pink stuff comes out of the pickup on the bottom of the boat.
I’ve done it this way for years using a small hand pump I rigged up with a length of hose that I can shove in the discharge on the outlet side of the pump and another length of hose in a bucket of AF on the pick up side of the hand pump.
It’s much easier if you have an assistant to hand pump while you hold the hose shoved in to the discharge on the boat.
 
Yup - as above, just pump the AF in through the discharge on the side of the hull. Often, you can wrap the hose with some tape to help make it fit tight enough so you don't need a helper... usually...

A spark plug boot on your hose works well...
 
Current boat is heated storage, but my last boat was stored outside. Used an air compressor and simply blew the water out from the discharge back to the pickup in the hull. Never had an issue.
 
Nope, don't need to have it working. Can do what any of the posters above said, or sounds like you usually pump the pink through using the system pump. Go ahead and do that if you wish. Run the pink through using one unit until it runs out both thru-hulls.
 
I've been winterizing mine by removing the strainer cover and then putting my (big) shop vac on the discharge port on the outside of the hull. It sucks all of the water right out in about 5 seconds.

The down side of this is, the pump looses it's prime, so at the start of the season you have to re-prime the pump to get things moving. PITA. For the cost of a gallon of pink, I pump just it thru the outlet.
