(See Water Drain Valve Location chart)
• Turn the diverter valve handle so that it points
toward the suction tube.
• Turn the water pump switch on.
• Open each hot and 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.
Dump and Clean Holding Tanks:
• Completely drain the sewage and waste water
holding tanks at an approved waste disposal
site. Drain the sewage tank first so the
following waste water can rinse any waste
solids from the dump outlet and sewer hose.
• Close dump valves and refit the dust cap onto
the drain outlet.
