1. Turn water heater power OFF (both electric & LP gas on
standard storage water heater). Single switch inside the RV
for Truma AquaGo tankless water heater. Set the colored
valves to SANITIZE as indicated on the utility center label.
This automatically bypasses the water heater.

. Use the clear plastic tube (supplied
with RV) to bypass the water lter.
4. 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.
5. Siphon the sanitizer solution into the fresh water tank; attach a hose to the city water
connection inlet. Insert the other end of the hose into a container holding the chlorine
solution.
6. Turn the pump switch ON (red LED will light). The solution will be drawn into the
fresh water tank. Turn the pump OFF when solution has been drawn into the tank. To
aid in siphoning, set the container on a surface approximately (2) feet o the ground.
The drain valves must be turned OFF.
7. Remove the chlorine container and nish lling the fresh water tank with clean (pota-
ble) water until the tank is full. Tank level can be viewed on the monitor panel inside
the RV (keep the valves set on ). Leave the hose attached to the city water
connection inlet; place other end of hose in a container of fresh water. Turn the pump
ON. Fresh water will be siphoned into the tank. Turn pump OFF when tank is full.
Disconnect the hose from utility center.
8. After the recommended amount of sanitizing solution is in
the tank make sure the water tank is full of fresh water, the
cartridge water lter (if so equipped) is bypassed or the lter
is removed from the full system canister water lter (if so
equipped), and power to water heater is turned OFF (both
electric & LP gas). Set the valves to the setting. Turn the pump ON
and sanitized water will ow into the water lines from the tank when a xture is opened.
