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,
The red light on the command center tank switch does not necessarily
indicate that ALL heaters are operating; it is a only a warning that the
heater circuit is ON.
Free draining is never recommended, especially in cold weather
use.
Toilet (If So Equipped)
The toilet is ecient and easy to operate. Prior to using the sanitation system, it is strongly
recommended to ush the toilet several times to release sucient water into the holding
tank. Generally, more water is required only when ushing solids.
The toilet system will perform better when water is run for ten to fteen seconds after ush-
ing to ensure that the waste will proceed to the bottom of the tank.
If there is not a sucient amount of water used during ushing, 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
always have four to six inches (10 - 15 cm) of water in the toilet. It is important to add
enough water to prevent solid waste buildup. The following guidelines will help to prevent
solid waste buildup.
The tank heaters are thermostat controlled and will cycle on and o while they are operating.
The +12VDC heaters stay on constantly. The thermostat controlled tank heaters turn ON at
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.
When liquid is present in the holding tanks and the outside temperature approach-
es and maintains freezing conditions 35°F (2°C) or colder.
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.
When ambient temperatures rise and remain above freezing.
No maintenance on the heaters is required, only a periodic inspection for loose wires, dam-
age, etc. For additional detailed information, refer to the tank heater manufacturer’s user
guide.
