Maybe Google Youtube for winterizing your model. I believe all 2018 Micro's have a 6g water heater (tankless heater was 2016 and earlier). Also have a tube to feed into your antifreeze container using the water pump to drain it.
1. So inspect the inside plumbing to the water heater you will see two valves connected to it - input and output. Close them.
2. Outside, open the heater cover, slowly remove the plastic drain plug with a 15/16" socket. Let it drain. I don't reinstall the plug, just leave it inside the heater cover.
3. Open the fresh tank drain underneath.
4. Open the grey/black dump valves.
5. Open all hot and cold taps including the outside shower, turn the water pump on to flush all fresh water. Shut off the water pump when the taps are sputtering.
6. Close the grey/black dump valves.
7. Open the valve for the winterizing tube, insert tube into the antifreeze container.
8. Turn on the water pump with all the hot and cold taps still open. The first gallon of antifreeze you should see pink coming out.
9. Turn off water pump when the first gallon of antifreeze is drained.
10. Insert winterizing tube into second gallon, turn water pump on and open the inside shower tap along with the other taps still open. This should provide a good solid pink from all taps.
11. Turn off water pump when the second gallon is drained.
12. Insert winterizing tube into third gallon, flush the toilet this time with all other taps still open. Third gallon should ensure you have full pink from all taps, inside and outside shower, toilet. Grey and black tanks should be good.
13. A fourth and fifth gallon if you think it is necessary, then close all taps.
14. Pour antifreeze into the fresh tank until you see pink from the drain valve.
15. Close fresh tank drain valve, close winterizing valve and you're done.
I don't skimp on winterizing. Antifreeze is $5 per gallon, buy eight gallons and drain them if it makes you comfortable.
