1 . After initial pump-out, add holding tank deodorant or cleaner to toilet bowl, and flush with water .
2 . Continue flushing and pumping out tank until holding tank discharge is clear .
7.2

Use only propylene glycol freshwater antifreeze to winterize the holding tank . Make sure the
antifreeze does not contain alcohol.

to the holding tank .
