With the water source turned ON, flush the black water holding tank until the water
running out of the black tank drain valve is clear (not discolored or cloudy).
4. Disconnect the garden hose and close the black tank drain valve. Fasten the sewer hose
housing dust cap back on the tank flush inlet.
Do not use the same hose to fill your fresh (potable) water tank that is used for

Tank Heaters (if so equipped)
Your recreation vehicle may be equipped with heaters for the fresh, gray, black water tanks
and the water lines or drain lines. The larger tank heaters are 120VAC and attach directly to
the tanks. Water line or drain line heaters are smaller and operate on +12VDC and will be
attached to the water lines or drain lines. These heaters will prevent water in the tanks and
lines from freezing down to -11°F (-24°C) (contingent on recreation vehicle setup).
The tank heaters are thermostat controlled and will cycle on and off 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.
The tank heater switch should be turned ON:

When liquid is present in the holding tanks and the outside temperature approach-
es 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.

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 only a warning that the
heater circuit is ON.
