ROUTINE MAINTENANCE
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.
DE-WINTERIZING
If the motorhome is equipped with an optional ice maker, the following additional steps should be
taken:
Whirlpool Residential Refrigerator Ice Maker (optional)
1. Unplug refrigerator or disconnect power.
2. Locate the water supply shut off valve and turn off the water supply.
3. Disconnect the water supply line at the refrigerator and drain supply line completely.
4. Locate ice maker fill tube at the rear of the refrigerator and follow the water line down to
the water valve.
5. Remove any covers if necessary.
6. Disconnect water line from water valve and drain water from line and valve. Use a small
pan to catch water.
7. Remove water filter cartridge (if applicable.) NOTE: Reinstall a new water filter cartridge
when refrigerator is put back into service.
