Using Nontoxic
Antifreeze
6 • 2 5 0
Ten gallons of FDA approved RV antifreeze will be required to winterize
the motorhome.
1. Remove the water filter elements from the filters and reassemble
the filters without the elements (see "Water Filter").
2. Open all faucets, low point drains (next to the Aqua-Hot) and drain
valves for the fresh water tank, water heater tank, holding tanks
and fresh water lines.
3. Close all faucets, drain valves and low point drains.
4. If the motorhome has a water heater, remove the anode to drain the
internal tank. At the back of the water heater turn the water valve
to the "by-pass" mode.
5. Pour the antifreeze into the fresh water tank using the fresh water
gravity fill.
6. Turn ON the system water pump and operate each faucet (hot and
cold valves) individually until a small amount of antifreeze is
present.
7. Close off the faucets.
8. Open the shower faucets and toilet valve to allow a small amount
of antifreeze to run into the holding tanks.
9. Use a soft cloth to wipe out the sinks and shower to protect
surfaces from antifreeze stains.
10. Open the exterior faucet using the same procedure as the interior
faucets.
11. If the motorhome is equipped with an icemaker, remove the ¾"
fitting and flush antifreeze through the water line.
12. Disconnect the power supply line affecting water pump operation.
To de-winterize, drain and fill the fresh tank with water. Connect the power
supply line for the water pump. Operate all faucets, one at a time, until clear
water is present.
WARNING: Use only specifically designed non-toxic RV antifreeze
for potable water systems. Automotive antifreeze, if ingested, can
cause blindness, deafness or death.
WARNING: It is recommended that a qualified RV service technician
familiar with motorhomes, such as an authorized dealer, do this
procedure.
