Close the hot water faucets and repeat opening all cold water faucets one by one until
you smell chlorine. Include outside shower faucets (if swo equipped) and toilet.
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, and for at least one hour if using a 100-PPM chlorine
concentration.
™ 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.
12. After the required period, drain the chlorine solution from the fresh water system.
Since the water heater was bypassed there should be no sanitizer in the (storage) tank
water heater.
Rinse the system with fresh water:
13. Fill the fresh water tank full of clean (potable) water. Fill fresh water tank from an
external container. Pour fresh water into the gravity fill inlet using a hose (or funnel).
14. Power to water heater should be OFF (both switches: electric and LP gas). When the
fresh water tank is full, turn the pump ON to send water through the lines. Water heater
bypass valves should still be set to BYPASS.

smell is gone. Turn faucets and outside shower off, turn pump OFF.
16. Drain the fresh water system again.
17. Set water heater bypass to NORMAL: Allows water into the water heater. Replace
the water heater drain plug.

turn the water heater power ON.
19. To verify water heater is full of water, turn on hot water faucets, turn pump ON. When
you get a steady stream of water through the hot water faucets, it should be full. Turn
off the pump and faucets.
If a chlorine taste lingers in the water, flush the water system with a solution consisting
of one-quart vinegar to five gallons of clean water. Re-flush as necessary. The vinegar
solution may damage the water heater or the water filter, so both must be bypassed
again before performing this operation.
Follow the steps outlined in Draining the Fresh Water System with one exception;
do not drain the water heater.
