Each new recreational vehicle is winterized with RV antifreeze before it is shipped to the
dealer. To use the water purication system, full system canister water lines need to be
ushed of antifreeze and then the lter installed in the canister before use.
Refer to the manufacturer’s owner’s manual and the label on the water lter cartridge for
further information.
Do not allow water in the canister housing to freeze.
Remove the lter before using anti-freeze to winterize the system or
chlorine solution to sanitize the system.
Flush canister housing thoroughly before it is put back into service after
winterizing or sanitizing.
For best results replace lter every 6-12 months.
Do not use carbon cartridges where water is microbiologically unsafe or
of unknown quality.
Maximum operating pressure is 125 psi (8.75 bar).
Maximum water temperature is 125° F (52° C).
Draining The Fresh Water System
Water tanks may be drained through a valve located near the tank. A recreational vehicle
with a demand pressure pump system will have low-point drains attached to the water lines
(normally located near the water tank).
