What is the Winterize toggle switch on outside panel on Fuzion 331 do?

What does it do?We are winterizing our toyhauler today and doing great with it but wondering about that switch. We have bypassed water heater and blown lines and have antifreeze in. Ready to tuck it in for season. Wanted to get out again but winter approaching here in Idaho. Here's to a great season next for all.

sounds your trailer is set up like mine - convenience center has 3 control levers and 3 inlets? If so, one inlet is black tank rinse, the next is freshwater inlet, and third is antifreeze inlet, and levers are: water tank fill, water heater bypass, and antifreeze on/off.

If you connect a short hose to the antifreeze inlet (I use an extra short freshwater hose that I cut in half, saving the other end for when I fill using the gravity fill) and then put the other end of hose into jug of rv antifreeze, the lever changes the pump inlet to where it sucks in antifreeze, rather than water from tank; it diverts the pump inlet.

We did a line blow out as well yesturday. We have a 395 and it came with a air compressor "like" connector on the outside shower/faucet connections. It would make things sooooo much easier if they had used a standard air compressor quick connect for that outside shower connection. They provide a hose that connects to that and has a water hose connection on the other end that I normally will use to connect a spray nozel to. If it has the right air compressor quick connect than you could use that hose connected to the water inlet and to the air compressor and everything would be very simple. Instead I had to purchase the blow out nipple and then rig up a hose to that and the air compressor to blow out the lines. I would think that it wouldn't cost Keystone any more to use an industry standard air compressor connection and then you would already have everything you need to winterize properly with out making a trip to the hardware store. Just my .02 cents on what I was working with.

I use that hose to run anti freeze through my black tank rinse. It's very handy for that. When I blow out the lines I use a camco blowout plug with quick connect

Just remember to run your water pump during part of your blow down process. There is a small amount of water that stays in the pump even during blow down. If you don't get it out you will be buying a new pump next spring. Guess how I know that.😳

ouch! Good tip. Sorry that it happened to you. Even using antifreeze inlet there's a few spots to remember. I still need to run a bit between the water heater bypass valve and the water heater, to make sure that bit of line doesn't freeze.
