6a. To clean the unit, turn on the water. Squeeze the actuator to allow the solution to
flow from the handle into the container. The suction line will remove the solution.
Continue this process for 5 minutes. Remember to keep the exposed tip of the handle
submerged in the solution.
6b. To disinfect the unit, turn on the water. Do not squeeze the actuator. After half of the
solution is removed, turn the water off at the faucet. Remove handle from solution
and rest in the handle rest/grip ring. This will trap solution in the return line and allow
effective disinfection. Follow manufacturer’s recommendations on soak times for
maximum benefit. Repeat the cleaning procedure above to remove any residual
disinfecting solutions.
7. Turn the water off and remove both tubes from the chamber.
8. To remove any stagnant solution in the tubing, disconnect the hoses from the
chamber and place the open end in the sink. Hold the handle higher than the tube
and squeeze the actuator. The water will run out of the open end into the sink basin.
9. Remove the chamber from the faucet. Allow the chamber to drip dry. Replace the
unit in its holding container.
10. To facilitate a recommended thorough flush and faster drying, pour isopropyl rubbing
alcohol inside the chamber and hoses.
If hard water/calcium buildup is a concern, a solution of 100% vinegar can
be substituted. Allow the vinegar to soak in the chamber for no more than
2-3 minutes. A final flush of isopropyl alcohol is required.
