freeze into the water lines. This feature is located
near the water pump and drain valves. See page
7-6 for location in your coach.
To Fill Lines with RV Water Line Antifreeze
· Turn water heater by-pass valve to BY-PASS
position.
· Remove and save the protective cap from the
end of the suction tube.
· Insert the end of the tube into a container of
RV antifreeze solution.
· Turn the diverter valve handle so that it points
toward the suction tube.
· Turn a water pump switch on.
· Open each cold water faucet handle in the
coach one at a time until antifreeze solution
just begins to flow from the faucet, then
close.
When Done Adding RV Antifreeze:
· Turn water pump switch off.
· Turn the diverter valve handle so it points
toward the water line to the pump as shown in
the photo. This will stop the flow from the
suction tube and revert the tank line flow to
the pump.
· Replace the protective cap onto the end of
the suction tube to keep out insects and debris
when not in use.
