9. Open all hot water faucets one by one until water begins to flow continuously and a
chlorine smell is noticeable. Include outside shower faucets (if so equipped). Close hot
water faucets. Repeat this process with the cold water faucets.
10. Turn OFF the water pump.
11. Let the solution remain in the tank and lines for at least four hours when disinfecting
with 50-PPM residual chlorine. If a shorter time period is desired, then a 100-PPM
chlorine concentration should be permitted to sit in the system for at least one hour
12. After the required period, drain the chlorine solution from the fresh water system.
Rinse the system with fresh water:
13. Fill the fresh water tank full of clean (potable) water. Use water from either a pressur-
ized source, or from a container (as detailed below).
a. Filling from a pressurized source: Set the valves to
the POWER FILL TANK setting. Connect a non-toxic
drinking hose to the city water connection inlet. Connect
the other end of the hose to the pressurized water source.
Turn on the water source. Turn off the water source when
the tank is full. Disconnect the hose from the water source first, then from the utility
panel. ( Do Not Overfill )
b.
Syphon filling from a water container:
Set the valves
to the SANITIZE setting. Insert a hose into the city water
connection inlet; place the other end of the hose in a con-
tainer of water. Turn the pump ON to draw water into the
tank. After the tank is full, turn the pump OFF. Remove the
hose and the container. To aid in siphoning place the con-
tainer on a surface approximately (2) feet off the ground. Drain valves must be off. ( Do
Not Overfill ).
14. Power to water heater should be OFF (electric and LP Gas
switches on standard storage water heater). Single switch
inside the RV for Truma AquaGo tankless. When the fresh
water tank is full, set the valves to the DRY CAMPING
setting. Turn the pump ON to send water through the lines.
15. Run water through all faucets (hot & cold, including outside shower) until chlorine
smell is gone. Turn faucets and outside shower off, turn pump OFF.
16. Drain the fresh water system again. If the RV has the full system canister water filter,
remove the canister, reinstall the filter, and reattach the canister.
17. Refill the fresh water tank with fresh water again and when water heater is full of water,
turn the water heater power ON.
NOTE: To thoroughly sanitize the fresh water tank, the unit should be
driven around for a period of time allowing the solution to splash the sides
and top of the tank.
