Disinfecting Fresh Water Systems On Rvs - Winnebago Cambria Owner's Manual

To Clean Pump Strainer
Be sure all water pump switches are OFF.
• Twist the inlet cap (bowl) counterclockwise to
unscrew from the strainer assembly.
• Remove the bowl and pull the strainer screen
out of the bowl to tap out any particles and
rinse clean.
• Insert the strainer screen back into the bowl,
then screw the bowl back onto the strainer
assembly.
NOTE: You must also empty the strainer when
winterizing your coach to avoid water
freezing and cracking the strainer bowl.
Water Pump Switch
Water pump switches are located on the
Systems Monitor Panel and in the utility
compartment. While the switch is in the "ON"
position, the pump will automatically supply
water pressure as it is needed. It is recommended
that the pump switch be turned off whenever you
are away from the vehicle or not using the water
system. A slow leak in a faucet could drain the
water system and discharge the coach battery.
Initial Water Line Priming
1. Make sure that all water drain valves are
closed, including water heater valve.
2. Turn water pump switch to "OFF" position.
3. Fill water tank.
4. Open all faucets, hot and cold.
5. Turn on pump switch.
6. Close each faucet as it begins to deliver a
steady stream of water (close cold water first).
Leave hot water faucets on until they also
deliver a steady stream of water. This will
ensure that the water heater is filled with
water.
7. Check to be sure pump stops soon after all
faucets have been closed.
8. Pump is now ready for automatic operation.
Pump will start when a faucet is opened and
stop when the faucet is closed.
DISINFECTING FRESH WATER
SYSTEMS ON RVS
As approved by the U.S. Public
Health Service
To assure complete disinfection of your fresh
water system, it is recommended that the
following procedure be followed on a new
system, one that has not been used for a period of
time, or one that may have become contaminated.
This procedure is also recommended before long
periods of storage such as over winter.
1. Prepare a chlorine solution using 1 gallon of
water and 1/4 cup of household bleach
(sodium hypochlorite solution). With tank
empty, pour chlorine solution into the tank.
Use 1 gallon solution for each 15 gallons of
tank capacity. This procedure will result in a
residual chlorine concentration of 50 ppm in
the water system. If a 100 ppm concentration
is required as discussed in item 3, use 1/2 cup
of household bleach with 1 gallon of water to
prepare the chlorine solution. One gallon of
the solution should be used for each 15 gallons
of tank capacity.
2. Complete filling of tank with fresh water.
Open each faucet and run the water until a
distinct odor of chlorine can be detected in the
water discharged. Do not forget the hot water
taps.
3. Allow the system to stand at least 4 hours
when disinfecting with 50 ppm residual
chlorine. If a shorter time period is desired,
then a 100 ppm chlorine concentration should
be permitted to stand in the system for at least
1 hour.
4. Drain and flush with fresh water.
WARNING
Chlorine is poisonous - recap bottle and
clean utensils after use.
