Luxury Coach Water Compartment (Example Only)
WHEN TO WINTERIZE A COACH
Although great care has been taken to build a well-insulated unit, recreational vehicles are not intended for extended
use in sub-freezing weather without special precautions. When the outside temperature drops below freezing, the
furnace must be turned on to keep the coach warm. Continued use in cold weather will require the coach to be
winterized.
It is critical to winterize the plumbing in your coach when storing it in temperatures below freezing or using it in extremely
cold conditions. If subjected to these conditions without being properly winterized, the heating system may be unable to
keep the coach and its compartments above freezing temperatures.
WARNING
Winterizing is the responsibility of the consumer. Make sure you have protected the complete water system
any time your coach is in freezing temperatures. Failure to complete the winterization process may result in
extensive damage to the water system, appliances, and coach.
IMPORTANT
A regulated compressed air supply is needed to properly complete this procedure. The pressure should be
regulated between 40 and 60 PSI (pounds per square inch). Higher pressures may cause damage.
HOW TO WINTERIZE A COACH
1. Drain the black and grey tanks. If equipped, also empty the macerator hose.
2. Drain the Fresh Water Tank. Open the tank drain valve located in the driver side water bay.
3. Turn off the switch(es) to the water heater or the hydronic heating system, including the burner and the 120
Volt element, depending on your coach's equipment.
4. Turn on the refrigerator.
5. While the tank is draining, remove all of the water filters. Install a bypass or the filter canister, including the
whole house, refrigerator, and drink water filters (whether standard or UV), if your coach is equipped.
6. For units with a tank-style water heater instead of
a hydronic heater, close the valves to the water
heater, and open the bypass valve, which is normally
located at the back side of the water heater.
Depending on your particular floor plan, access to the
back of the water heater may be located in a cabinet,
the closet, or in an exterior compartment.
