4.
Top off water tank with fresh water and wait 3 to 4 hours.
5.
Drain the entire system by opening all fresh water tank valves, faucets and plumbing
line drain valves.
6.
Flush the system with drinking quality water, close drain valves and refill the water tank
with fresh water and repeat the steps set out in step 3 (omitting the chlorine solution).
Let the fresh water flow through the system for several minutes to flush out the chlorine
solution.
7.
After you finish flushing the fresh water system drain the entire system by repeating the
steps set out in step 5. You can now close the tank valve, faucets, and drain valves and
fill the tank with fresh drinking quality water. The system is ready to use.
8.
To remove any excessive chlorine taste or odor which might remain in the potable water
system, prepare a solution of one quart vinegar to five gallons water. Allow this solution
to agitate in tank through vehicle motion. Drain tank and flush again with potable water.
ELECTRIC 12-VOLT DC WATER PUMP: The onboard fresh water system is pressurized by a self-
priming, 12-volt DC pump. The water pump operates automatically when the water pump power
switch is "ON" and a faucet or valve is opened. Turn the water pump "ON" to pressurize the system.
When a faucet is opened after the initial filling of the tank, the water may sputter for a few seconds.
This is normal and is not cause for concern. In the “ON” position the water pump delivers water to the
water heater and faucets and maintains a positive pressure through the system. IMPORTANT: It is
recommended to turn the water pump switch “OFF” whenever you are away from the camper.
IMPORTANT: Do not run the water pump without water in the system.
WASTE WATER SYSTEM
The waste water system in your camper is made up of sinks, tub, shower, toilet, plumbing drain, vent
lines, "gray water" holding tank and a "black water" holding tank. The holding tanks make the system
completely self-contained and allow you to dispose of waste water at your convenience. A flexible
sewer hose is required to connect the holding tank outlet to the inlet of an approved waste water
dump station or sewer system. The drain plumbing is very similar to that used in your home. The
system is trapped and vented to prevent waste gases from backing up into the camper. The drain
plumbing is durable and resistant to most chemicals. All drain plumbing except the toilet connection
terminates in the gray water holding tank. The toilet is mounted on the black water tank and flushes
directly into it.
The holding tanks terminate in a valve arrangement that permits dumping each tank separately. The
valves are called "knife valves." A blade closes the opening in the sewer drain pipes. The blade is
connected to a T-handle that is pulled to release the contents of the tank(s). During self-containment
use, the sewer line is securely capped to prevent leakage of waste material onto the ground or
pavement. DO NOT PULL THE HOLDING TANK KNIFE VALVE OPEN WHEN THE PROTECTIVE
CAP IS INSTALLED ON THE PIPE. Always ensure that the tank is evacuated into an acceptable
sewer inlet or dump station.
