PLUMBING SYSTEM
your vehicle speed until you reach a dumping
station. When connected to the sewer drain
line at a campground, keep the “black tank
drain” valve closed until the holding tank is at
least ¾ full. This should provide sufficient
water to assist in complete draining of the
black water holding tank. Repeat as needed.
Before using the RV or after dumping the grey
and black water holding tanks, always add the
proper amount of deodorant to the black
water tank to prevent malodors and help
break down holding tank contents (unless
winterizing). Follow the deodorant bottle or
package instructions. Driving to a disposal
site will normally loosen any accumulated
waste debris or solids from the sides of the
holding tanks.
Never leave the black tank drain in the open
position continuously when connected to the
campground sewer system.

A pad is attached to the exterior bottom side
of the holding tank. Heat is supplied by 12-volt
DC power through the heating element built
into the pad. Approximately 6-8 amps of
energy per pad is consumed and fused
through the 12-volt power supply board. An
internal thermostat is built into components of
the heat pad to control temperature and assist
in energy conservation.
The control switch to turn the holding tank
heat pads ON or OFF is located on an interior
wall in or near the bathroom. Power to heating
pads should be turned off until:
1. Water is in the holding tank.
2. The temperature drops to 34°F (1°C).
3. The motorhome is parked, set up and all
attachments performed.
Turn the heated holding tank pads OFF
when dumping and draining the holding
tanks.
*Heated holding tank pads are not designed to
assist in sub-freezing weather. See Cold Weather
Usage, Section 11.

RAINS
The grey tank drain and black tank drain are
also referred to as dump valves. Always drain
the black water holding tank first so the
following grey tank waste water can help rinse
any solids or debris from the dump outlet and
sewer hose.
1. To make drainage easier, level the RV.
2. Remove the sewer hose housing dust
cap, and attach the sewer hose.
Do not add automotive antifreeze or
caustic chemicals such as laundry
detergents into the holding tanks. Although
these products may have a deodorizing
effect, they may damage the plastic and
rubber parts of the plumbing system or the
components.
3. Place the end of the sewer hose into the
approved dump station.
4. Open the black tank dump valve (close it
when the black water holding tank is
emptied).
5. Open the grey tank dump valve (close it
when the grey holding tank is emptied).
6. Remove, clean and store the sewer hose.
7. Close the sewer hose housing dust cap.
Most states and parks have strict laws and
regulations to prohibit dumping of wastes into
any kind into anything other than proper
disposal facilities or sewer systems. Almost all
privately owned parks offer a campsite
hookup for sewage. You can locate many
dump stations throughout the United States
and Canada in Woodall’s, Rand McNally
Camp Guide, Good Sam Camp Guide, KOA
Kampgrounds Camp Guide and various other
publications. Some fuel stations also have
dump stations.
Please contact your RV dealer for assistance
in the purchase and installation of a sewer
hose and/or sewer hose extension (if
needed).
