11-8
A safety circuit in the control module monitors flush ball operation. If foreign objects or low voltage prevent the
flush ball from closing, this circuit prevents personal injury or damage to the flush valve monitor. If this condition
occurs, reset the control module by placing the Mode switch into the SERVICE position temporarily, then returning
it to the NORMAL position.
The toilet should be cleaned regularly for maximum sanitation and operational efficiency. Clean the toilet bowl with a
mild bathroom cleaner.
DO NOT USE CHLORINE OR CAUSTIC CHEMICALS, SUCH AS LAUNDRY BLEACH OR
DRAIN-OPENING TYPES, AS THEY WILL DAMAGE THE SEALS IN THE TOILET AND DUMP VALVES.
Refer to the toilet-manufacturer’s owner’s manual in your Allegro Bus Owner’s Information Package for complete
instructions and a detailed troubleshooting guide.
Caution
It is important that you use as much water as possible with each flush. This will help
prevent tissue and other solids from clogging the holding tank outlet.
P-Traps
Each of the sink drains, the shower drain, and the washing-machine drain (if so equipped) has a water trap (Ptrap)
to prevent holding-tank odors from entering the motor home. These traps must have water in them to trap odors.
When the vehicle is in motion, the water may splash out of the sink and shower drains. When the motor home is stored,
the water may evaporate from these traps allowing odors to enter the motor home. If this occurs, run water from the
faucet into the drain, thus allowing water to fill the traps again. A good practice would be to run a little water into these
drains on a monthly basis.
Black-Water Holding Tank
The “black water” (i.e., sewage) holding tank is located directly beneath the toilet. Before using the toilet, you will need
to treat the tank with water that is mixed with an odor-controlling chemical. These chemicals are readily available at any
RV supply store. Be careful not to spill the chemicals on your hands, clothing, or the carpet because such may cause a
permanent stain. Pull the toilet levers forward to allow the chemicals to mix with the toilet water. Continue pulling the
toilet levers until a depth of at least one inch of solution is directly under the toilet. Release the levers and the waste
tank is now ready for use.
Caution
Use only approved RV odor-controlling chemicals in the holding tanks.
Products containing ammonia and petroleum will damage the ABS plastic
holding tanks and seals.
