Using Non-Toxic Antifreeze

Approximately five to eight gallons of FDA approved antifreeze will be required to winterize the motorhome.

WARNING

It is recommended that a qualified RV service technician familiar with motorhomes, such as an authorized dealer, do this procedure.

WARNING

Use only specifically designed, non-toxic, FDA Approved RV antifreeze for potable water systems.

NEVER use automobile engine antifreeze. If ingested, antifreeze can cause serious injury or death.

NOTE

Freeze damage is not covered under warranty.

1. Empty and flush the holding tanks.

2. Disconnect the water line connections on either side of the water filter bowl head. Connect the bypass hose to the water lines. Unscrew filter bowl, remove old cartridge and empty any remaining water in the bowl. DO NOT screw filter bowl back onto filter head (see “Water Filter.”).

3. Drain the fresh water tank by opening the fresh water tank drain valve.

4. Open fresh water tank low point drain valve, winterization valve, low-point drain valves, water pump shut-off valve and allow water to drain.
