Sanitizing; Sanitizing The Fresh Water System; Sanitizing The Fresh Water Tank - Airstream INTERSTATE 24 2024 Owner's Manual

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
• RV antifreeze hand pump kit with a garden faucet
fitting/connector
• City water fill hose to connect to city water; choose
one that is acceptable for RV use (tasteless/
odorless/non-toxic)
• A hose with a garden faucet fitting/connector at
one end and nothing at the other (to pump fluid
from a gallon-size container into your water inlet)�
Your city water fill hose may work if it will fit into
the opening of your container; choose one that is
acceptable for RV use (tasteless/odorless/non-
toxic)
For the following procedures, you will need to know
how many ounces of bleach to add to your bleach/
water mixture� Multiply "gallons needed" by 0�13; the
result is the ounces of bleach needed� To reduce the
amount of time it takes to disinfect the tank from four
hours to one hour, double the ounces of bleach�

Sanitizing the Fresh Water System

1� Mix 2-3 gallons of bleach/water solution using the
guidelines above�
2� Set the Water Management Panel selector to the
Winterize/Sanitize Fixtures setting�
3� Connect a hose to the Water Management Panel
inlet and place the other end in the bleach water
mixture�

4� OPEN all faucets (hot and cold)�
5� Turn the water pump ON and run it until the
mixture starts coming our 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� Turn the pump
off as you empty and transition from one container
to the next�
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� Set the Water Management Panel selector to the
City Fixtures setting�
8� Connect to a city water supply and allow the
faucets to run until the bleach/water solution is
flushed from the system.

Sanitizing the Fresh Water Tank

1� Determine the amount of bleach you need for your
tank capacity using the guidelines above� Tank
capacity is listed in Section 4�
2� Pour the bleach into a 1-gallon container and fill it
with water to make a bleach/water concentrate�
3� Set the Water Management Panel selector to the
Tank Fill setting�
4� Connect the hand pump kit to the Water
Management Panel inlet and place the other end
into the container�
5� Pump the concentrated bleach mixture into the
fresh water tank; disconnect the hand pump kit�
6� Fill the tank using a city water connection and
leave the solution in the tank for 4 hours of contact
time to complete the disinfection process� Or, if
doubling the required bleach, 1 hour�
7� Drain the tank, refill from the city water connection,
and drain again� Repeat until the bleach solution is
flushed out.
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
