Disinfection
Potable water systems require periodic maintenance to deliver a consistent flow of potable
water. Depending on use and system environment, disinfection is recommended prior to storing
and before using the water system after a period of storage. Systems with new components, or
ones that have been subjected to contamination, should also be disinfected as follows:
1. Dilute the appropriate amount of bleach (Alto 17 = 60 ml; Alto 21 and 24 = 100 ml) with a
little water.
2. Pour the solution (water/bleach) into the tank and fill the tank with potable water.
3. Activate water pump with “PUMP” switch (photo F-1.3) (Indicator light is “ON”). Open all
faucets (Hot & Cold) allowing the water to run until the distinct odor of chlorine is
detected.
4. The standard solution must have four (4) hours of contact time to disinfect completely. If
you double the solution, this concentration drops the time to one (1) hour.
5. When the contact time is completed, drain the tank.
6. Refill with potable water and purge the plumbing of all sanitizing solution.
NOTE: The sanitizing procedure outlined above is in accordance with the approved procedures
of RVIA ANSI Al19.2 and the US Public Health Service.
NOTE: A valve, located behind the axle between the wheel (left side) and the chassis (or close to
the waste valves depending to model) (photo E-2), will drain the potable water tank.
