44°F (7°C) and will turn OFF at 64°F (18°C). All of the heaters are controlled by a single
ON/OFF switch.
Typically, this red tank heater ON/OFF switch is located on the command center panel or in
the bathroom. The switch lights up red when it is turned ON and controls the heater circuit.
IMPORTANT: In order for the 120VAC tank heaters to be in operation, the
recreation vehicle MUST be hooked up to shore power or under generator power. If
the recreation vehicle is not operating on shore power or generator power, only the
+12VDC heaters will operate. This can result in the tanks freezing. The red light on
the command center tank switch does not necessarily indicate that ALL heaters are
operating; it is a warning that the heater circuit is ON.
The tank heater switch should be turned ON:
When liquid is present in the holding tanks and the outside temperature approaches and
maintains freezing conditions 35°F (2°C) or colder.
The tank heater switch should be turned OFF:
When there is NO liquid present (tanks are empty).
When dumping the black and gray holding tanks and the drain pipes.
When fresh water tank and supply lines are empty or being drained for storage.
When the recreation vehicle is connected to city sewer and the gate valves are open.
NOTE: Free draining is never recommended, especially in cold weather use.
When ambient temperatures rise and remain above freezing.
No maintenance on the heaters is required, only a periodic inspection for loose wires,
damage, etc. For additional detailed information, refer to the tank heater manufacturer's
user guide.
Toilet
The toilet is efficient and easy to operate. Prior to using the sanitation system, it is strongly
recommended to flush the toilet several times to release sufficient water into the holding
tank. Generally, more water is required only when flushing solids.
The toilet system will perform better when water is run for ten to fifteen seconds after
flushing to ensure that the waste will proceed to the bottom of the tank.
It is important to prevent solid waste buildup. Follow the toilet
manufacturer's recommended instructions each time after emptying the
black water holding tank.
To prevent help toilet blockage, always use RV grade single-ply toilet
paper. Do not flush paper towels, diapers, sanitary napkins or other
foreign objects down the toilet.
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.
If there is not a sufficient amount of water used during flushing, the waste materials may not
evacuate properly from the drain line to the tank. Clogged tanks and pipes could eventually
occur. For added convenience and better sanitation system performance, it is advisable to
