DE-WINTERIZING

1. To de-winterize your vehicle, open both of the low-point drains to allow the antifreeze
solution to drain from the water system.
2. Next, close the low-point drains and connect your vehicle to the city water system. Put
water in the freshwater tank and pump at least one gallon through the water pump to re
move the antifreeze from the water pump. Keep the water heater in the bypass mode.
3. As in winterizing, open the kitchen faucet, bath faucet, inside and outside showers, turning
"on" both the hot- and the cold-water valves and flushing the stool until the antifreeze solu
tion is flushed out of the system and the water flow is clear.
4. Once the system has been flushed, open the water heater bypass valve. Open the freshwater
tank supply valve from the pump and the icemaker valve.
5. Reinstall the (optional) water filter. Fill the water heater and hot water lines before turning
the water heater on.
6. Be sure to close the fresh water tank drain valves to allow the tank to fill.
