Waste (grey) holding tank preparation
No special preparation is required, however, placing a small quantity of chemicals
into this tank, such as baking soda or an approved RV chemical, will reduce odors
from food particles in the system.
Cleaning & Maintenance
The toilet should be cleaned regularly for maximum sanitation and operational
efficiency. Do not use chlorine (undiluted) or caustic chemicals, such as laundry
bleach or drain opening types, in the toilet system. These products damage the
seals in toilets and dump valves.
