NOTE:: Valve D is the suction (siphon) valve that has the clear
hose attached to it for siphoning in antifreeze, sanitizer or fresh water
from an external container. Valve E (if equipped) is a shutoff valve
for the fresh water tank. Valves D and E are typically located at the
water pump.
When to sanitize:
When your recreation vehicle is new.
At the beginning and end of each season.
When the water system becomes contaminated or every three months of use.
How To Sanitize
1.
Turn water heater power OFF (storage style-both electric and LP gas switches; tank less
water heater turn power switch OFF).
Set the bypass valves to the BYPASS position. (refer to Water Heater Bypass Valves
2.
section).
3.
Level the RV and drain the fresh water system (see Draining the Fresh Water System).
4.
Close the low point drain valves and the fresh water tank drain valve.
If the RV has a cartridge type water filter it must be removed and bypassed using the
5.
(supplied) bypass tube. Sanitizer should never be allowed into a water filter.
6.
Prepare a chlorine solution using 1/4 cup of household bleach (sodium hypochlorite
solution) to one gallon (3.785 liters) of water in a container. Prepare one gallon of
solution for every 15 gallons of tank capacity. This will result in a residual chlorine
concentration of 50 ppm in the water system.
If a 100-ppm concentration is required, use ½ cup of household bleach with one gallon
of water to prepare the chlorine solution. One gallon of the solution should be used for
each 15 gallons of tank capacity.
NOTE: Fresh water tank sizes vary by model; contact your dealer
or customer service for your specific tank size.
7.
Put the sanitizer solution in the fresh water tank. Insert one end of a hose (or funnel) in
the gravity fill inlet; insert the other end into a container holding the chlorine solution.
Do not use your non-toxic drinking water hose. Pour the chlorine solution into the
gravity fill.
8.
Remove the hose (or funnel) and container used to pour the chlorine solution, and con-
tinue filling the fresh water tank with clean (potable) water until tank is full. Pour fresh
water into the gravity fill inlet until tank is completely full. After the recommended
amount of sanitizing solution is in the tank, the water tank is full, and water filter has
been removed and bypassed, turn the pump ON which sends sanitizer into the water
lines.w
Open all hot water faucets one by one until water begins to flow continuously and a
9.
chlorine smell is noticeable. Include outside shower faucets (if so equipped).
