Cleaning
■ Use only non-abrasive, non-petroleum products to clean the toilet.
Thetford's Aqua-Clean is a non-abrasive, all-purpose cleaner spe-
cially formulated to be safe for all components of your toilet system.
■ Never use household cleaners, which can contain bleach, in the
toilet system. Household toilet bowl cleaners contain harsh acids.
Bleach, petroleum-based products, strong acids and abrasives can
cause irreversible damage to the toilet system and components.
Winterizing
■ Use only propylene glycol based, non-toxic RV antifreeze when stor-
ing toilet during freezing conditions. Never use automotive antifreeze
or windshield washer fl uid to winterize.
■ Make sure that both the entire supply and discharge systems are
thoroughly winterized to ensure complete protection for your system.
Storage
When storing the system for more than two weeks, thoroughly clean toilet
and hoses by following the instructions on Thetford Storage Deodorant.
Seasonal Start-Up
Test toilet before using by fl ushing to check operation. Verify that there are
no leaks.
Tissue
To facilitate fl ushing, it is recommended that you only use toilet tissues
specifi cally designed to disintegrate rapidly (unlike household tissues),
such as Thetford's Aqua-Soft
