De-Winterization
To de-winterize: drain and ll the fresh tank
with water. Connect the power supply line for the
water pump. Switch the winterizing valves back to
normal ow position. Operate all faucets, one at a
time, until clear water is present. Add water to water
heater. Install new water lters if so equipped.
NOTE:
The first two trays of ice
from the icemaker may
contain contaminants.
Discard and replenish ice
as necessary.
Prevent-A-Freeze System (Optional)
Depending on the size of the motorhome, as
much as eight gallons of FDA approved, potable
RV antifreeze will be needed to be added to the
storage tank.
The storage tank is located behind the water
service center. Remove the panel in the pass-
through storage bay next to the service center to
access. The Prevent-A-Freeze winterization switch
is located on the service center.
1. Turn the water pump off.
2. Fill the storage tank (located behind
service center) with FDA approved,
potable RV antifreeze. Ensure the valves
in the line between the storage tank and
Prevent-A-Freeze valve are open.
3. Open all low point drains and drain
valves to drain the fresh water tank and
fresh water lines. The fresh water tank
drain is located in a front roadside bay
and low point drains are located in the
water service bay.
4. Remove water lter housing and
replace with a diverter hose. The
water lter is located behind the water
service center.
5. Drain and ush the holding tanks.
Close valves when tanks have drained.
6. Close all faucets, drain valves and low
point drains.
7. Set the Prevent-A-Freeze switch to
“Winterize.”
8. Turn the water pump on and operate
each faucet individually until a small
amount of antifreeze is present. It may
be necessary to add additional antifreeze
to the storage tank. Allow about a cup to
run into all drains to ll traps.
9. Close all faucets.
10. Open the shower faucets and toilet
valves to allow a small amount of
antifreeze to run into the holding tanks.
11. Use a soft cloth to wipe out the sinks
and shower to protect surfaces from
antifreeze stains.
12. Exterior faucet or shower head should
be opened and closed using the same
procedures as the interior faucets.
13. If applicable, winterize the washer-
dryer (see “Winterize the Washer-
Dryer”).
14. If the motorhome is equipped with an
icemaker, see the refrigerator manual
for winterization procedure.
15. Turn water pump off.
16. Open a hot and cold faucet to relieve
line pressures then close the faucets.
17. Leave Prevent-A-Freeze switch
in “Winterize” position until de-
winterization.
WARNING:
Use only non-toxic RV antifreeze for
potable water systems. Automotive
antifreeze, if ingested, can cause
blindness, deafness or death. Always
keep antifreeze away from pets.
