Maintenance
2023 Rangeline
9-7
CAUTION
Failure to check the quick disconnect fitting for
water leaks when reinstalling inlet and outlet
hoses or the water pump strainer may cause the
pump system to leak, causing damage to personal
property.
NOTE
Turn the water pump off when the touring coach is
left unattended or in motion.
Sanitizing
Potable water systems require periodic maintenance
to deliver a consistent flow of fresh water. Airstream
recommends sanitizing before and after storage,
after new component installation, and if the system is
contaminated� When determining how often to sanitize
the system, consider environmental factors, usage,
and the quality and taste of the water coming out of the
system�
Decide whether you want to use an RV fresh water
cleaner & deodorizer or a mixture of bleach and water�
The following instructions are for the use of bleach�
If using an RV fresh water cleaner and deodorizer,
follow the instructions on the container for mixture
and contact time, and use the instructions below to
introduce the solution into the system�
Gather the following supplies ahead of time� These are
available at most RV supply stores:
• RV fresh water cleaner & deodorizer; or bleach�
• Gallon-size container(s) or a clean bucket suitable
for potable water�
• Container from which you can pour the sanitizing
mixture into the gravity water fill or an RV
antifreeze hand pump kit�
For the following procedures, you will need to know
how many ounces of bleach to add to your bleach/
water mixture� Use this formula:
Tank Capacity x �13 = Amount of Bleach Needed
To reduce the amount of time it takes to disinfect the
tank from four hours to one hour, double the amount of
bleach�
Sanitizing the Fresh Water System
1� Determine the amount of bleach you need for your
tank capacity using the guidelines above; see
Specifications on page 4-3 for tank capacity�
2� Pour the bleach into a container and fill it with
water to make a bleach/water concentrate�
3� Using the gravity water fill, pour/pump the
concentrated bleach mixture into the fresh water
tank and fill the tank with water; see Gravity
Water Fill on page 6-6 � Monitor tank level on the
Multiplex home screen�
4� OPEN all faucets (hot and cold)�
5� Turn the water pump ON (Multiplex home screen)
and run it until the mixture starts coming out of the
faucets and the odor of chlorine is detected� Once
the solution is running from the taps you can start
closing them. Move from one fixture to the next,
shutting them off as you go until all the lines are
full�
6� Turn the pump OFF and leave the solution in the
system for 4 hours of contact time to complete
the disinfection process� Or, if doubling the bleach
concentration, 1 hour�
7� Drain the tank, refill with fresh water, and run
the faucets until the bleach/water solution is
flushed from the system. For fresh water tank
drain location, see Component Locations for
Winterization on page 9-10�
NOTE
The sanitizing procedure outlined above is in
conformance with the approved procedures of
RVIA ANSI A 119.2 and the U.S. Public Health
Service.
