STEP 3
Step 3 - Open all the hot and cold-water faucets, to
include the shower fixtures (both inside and outside
showers);
STEP 4
Remove the drain plug from the fresh water tank and
allow it to drain completely� The tank and drain plug are
located on the driver’s side just behind the front axle;
STEP 5 Set the water selector lever in the wet bay to “City”;
STEP 6
Attach an air compressor line with the appropriate
Schrader valve adapter to the fresh water inlet in the
wet bay� Set the air compressor pressure regulator to
no greater than 30 psi;
STEP 7
Use the compressed air to blow out the water lines to
unsure all water has been purged from the hot and
cold supply lines;
STEP 8
Remove the air line from the fresh water inlet and set
the water source lever to “Tank”;
STEP 9
Pump 5 gallons of -50°F propylene glycol non-toxic
RV antifreeze into the fresh water tank� Alternatively
the antifreeze may be pumped directly into the system
at the water pump, using the winterizing valves�
Connect the RV antifreeze source to the fill connection
fitting. Close the water supply shutoff valve and open
the antifreeze fill valve. Then pump the RV antifreeze
into the system;
STEP 10
Close all faucets and shower fixtures. Then turn on
the fresh water pump� Do not turn on the water pump
if filling the system from the antifreeze fill connection
fitting per Step 9 above;
STEP 11
Flush the toilet until pink RV antifreeze flows into the
bowl� Allow at least one gallon of antifreeze to enter
the tank;
STEP 12
Open each hot water faucet (one at a time) in the
following sequence, allowing the water pump (or the
alternate RV antifreeze supply via the onboard fill
connection) to run until pink antifreeze flows steadily
from each fixture: bathroom sink; bathroom shower
head; galley sink; and, the outside shower.
STEP 13
Repeat Step 12 for each cold water faucet and the
shower heads following the same sequence;
STEP 14
Turn off the water pump� If you are alternatively using
the onboard RV antifreeze filling connection fitting,
turn off the fill valve, remove the antifreeze supply, and
reopen the water supply shutoff valve� Do not forget
this important step, as water / antifreeze will flow back
into the coach if the fill valve is not closed;
STEP 15
Take your coach to an RV pumpout station and empty
both the gray and black tanks completely; and,
STEP 16
Pour ½ gallon of RV antifreeze down each sink drain,
and the shower drain to ensure the drain lines and the
holding tank dump valves are properly protected�
