TOILET
The Thetford toilet installed in your recreational vehicle is connected to the pressurized fresh water system.
There are two flush modes available, controlled by the mode selector switch located at the back of the toilet.
Up is user control/water saver mode and down is residential mode. For residential mode touch the large
button once and walk away. For user control mode hold down large button for as long as you’d like to flush.
Unnecessary frequent flushing of the stool will quickly deplete your fresh water supply and fill your holding
tank. If the black water tank becomes full, you will no longer be able to flush the stool until the tank can be
drained.
Follow the toilet manufacturer’s recommendations supplied in back of this book.
WATER SYSTEM WINTERIZATION
If you intend to store your RV through periods of subfreezing weather in an unheated environment, it will be
necessary to winterize the water system. Damage to water system components will result if proper
winterization steps are not taken.
1.
Level the unit for good system drainage.
2. Drain the waste water tanks as previously outlined.
3. Turn the water pump switch off.
4.
Open all faucets, and the water heater drain.
5. Open low point drains on the water lines.
6. Drain the fresh water tank.
7.
Blow the water lines out using compressed air (through the city water hook up not to exceed 60 PSI).
8. When all lines are drained, close water tank valve, water heater drain, and low point drains on water
lines.
9. Fill the fresh water tank with a non-toxic antifreeze solution per the product directions.
10.
Turn on the water pump, and allow the winterizing solution to circulate and fill the system.
11. Close each faucet as solution flows freely from it. This also includes the water line to toilet.
12. Turn off the water pump.
Before using the system again in warmer weather, completely flush the systems with water, flush the toilet,
and sanitize the entire fresh water system. When using the RV during cold weather, and water in a tank or
drain line should happen to freeze, you should take immediate steps to thaw it before damage to the system
occurs. DO NOT continue to use the water system components if such a condition exists. If damage has
occurred, make sure to have it repaired before using again.
