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 remove the antifreeze from the water pump.
Keep the water heater supply valve closed and the water heater bypass valves open. The supply valve for the
freshwater tank from the pump must remain closed.
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 solution is flushed out of the system and the
water flow is clear.
4. Once the system has been flushed, open the water heater supply valve and close the water heater bypass valve.
Open the freshwater tank supply valve from the pump and the icemaker valve. Be sure that the water heater
tank is completely filled with water before turning "on" the water-heater power or else significant damage to
the tank and its plumbing may result.
5. Reinstall the (optional) water filter.
6. Be sure to close the fresh water tank drain valves to allow the tank to fill.
Washer/Dryer (Optional)
1. Flush the water pipes.
2. Reconnect the water inlet hoses to the corresponding HOT and COLD faucets; then turn "on"
both water faucets.
3. Plug in the washer/dryer and /or reconnect the power.
4. Run the washer through the "Express" cycle with ó tablespoon of powder detergent (or liquid equivalent) to
clean out the antifreeze. This completes the process.
