Utility Center with Antifreeze
1. Drain the water tank and water heater completely by opening all faucets and low
point drains until the tank and water heater are empty. Make sure all holding tanks
are empty.
2. Position the “Control Valves” on the “Utility Panel” to the “Antifreeze/Sanitize
Lines” configuration. (Fig. 4-6) The low point drains located directly below the
utility center must be closed for the antifreeze to siphon through the lines.
3. Attach the intake hose to the “City Water Connection.” (Fig. 4-8)

WARNING: Do not use Ethylene Glycol (automobile antifreeze) or
methanol (windshield washer fluid) in your fresh water system. They
are harmful and can be fatal if swallowed.
4. Put the free end of the hose into a jug of NON-TOXIC RV Antifreese. You will
need more than one gallon of antifreeze.
5. Turn the “Water Pump Switch” (Fig. 4-7) to the “ON” position and open each faucet
until the antifreeze flows through. Do not forget to run the antifreeze through the
toilet.
6. Pour at least one cup of antifreeze into each drain to protect the p-traps.
7. Before using the water system again, open the valves A, B, and C, then sanitize and
flush the whole system. (See instructions under “Sanitizing – Units with Utility
Centers.)
There are three methods of winterizing your travel trailer based upon the model of your
unit. Please read and understand all instructions before beginning.
Air Pressure (all models)
This method will utilize an air hose to blow excess water from the water lines.
1. Make sure all holding tanks are empty.
2. Run the pump until it is dry, this will take approximately 15-20 seconds.
3. If your unit has the utility center, make sure that the five (5) valves are set up in the
antifreeze/sanitize configuration. (Fig. 4-6)
4. Using an air hose and adapter, blow air through the city water connection.
5. Leave the faucets, drains and toilets open. Any remaining water will blow out in
five to ten minutes.
6. Pour one cup of NON-TOXIC RV antifreeze into all drain P-traps.
Water Heater Bypass with Antifreeze
This method utilizes a water heater bypass kit, available in most units, to avoid filling the
entire water heater with antifreeze.
1. Make sure all holding tanks are empty.
2. Turn off the pump.
3. Close valves A, B and D. Open valves E and C.
4. Drain the water heater and fresh water tank. (Consult the water heater owner’s
manual for details.)
5. Put the hose from valve E into a jug of
NON-TOXIC
RV antifreeze. You will need
more than one gallon of antifreeze.
6. Turn on the pump and open each faucet until the antifreeze flows through. Do not
forget to run the antifreeze through the toilet.
7. Pour at least one cup of antifreeze into each drain to protect the P-traps.
8. Close valve E.
9. Before using the water system again, drain and flush the water system. Close valve
C and open valves D, A, and B. Sanitize and flush the whole system. It is now ready
for use.
To winterize: Valves A, B, and D are closed; E and C are open.
