5. Fill the bucket half full with water and add one cup of household bleach. Attach the battery drill to the
pump insuring that the drill rotation matches the rotation needed to work the pump.
6. Using the drill, pump the solution from the bucket into the fresh water tank until solution is gone.
Remove the pump/drill apparatus and complete filling the tank with water.
7. Switch the water pump to the ON position. Open all faucets one at a time until all air is purged, and the
water flows freely. Once the tank is half empty turn off the water pump, open the gray water tank drain
valve and leave the valve open.
8. Again, add water to the tank until it is full. Allow the system to stand undisturbed for at least 15
minutes.
9. Turn the water pump on to drain the system by opening all faucets, and the fresh water tank drain
valve, while flushing the system with potable water.
10. Continue flushing the system, allowing the water to flow for several minutes, and then turn off the
water pump. Close the fresh water tank valve, gray water tank valve, and faucets. Refill the system
with potable water.
NOTE:
If you would rather not do the above, having your dealer perform this operation would be another
option you could choose.
