CleanZone Operating Procedures

An instructional sticker is on the side of every CleanZone cart and station, along with the LED light as well as the “Start” button to activate the sanitizing cycle. (shown below).

Make sure the LED light is GREEN. This indicates that the system is ready to use and any previous cleaning cycle has been completed.

  • Load your devices as usual into the system.
  • Be sure to fully close and lock all doors of the cart or station.
  • To begin the ozone cleaning cycle, press and hold the silver START button for approximately 2-3 seconds.
  • The LED will turn RED, indicating that the ozone decontamination cycle is in progress.
    DO NOT open the doors of the system at any time while the LED is RED.
  • You will hear the fan motor during the entire sanitizing cycle; this circulates the ozone throughout the sealed space.
  • Once the cycle is complete and the ozone has dissipated back to oxygen, the LED light turns GREEN and the cart/station is safe to open.
  • Unlock doors—ready to use clean devices.

The sanitizing cycle takes approximately 15 minutes to complete.

NOTE: As an added precaution, we recommend that users—especially those who may be more sensitive to smells or suffer from any respiratory-related issues—maintain a minimum distance of six feet from the CleanZone system during the cleaning cycle.

GREEN LED MEANS GO: Cart/Station can safely be opened and utilized

RED LED MEANS STOP: The decontamination cycle is active, so don’t open the cart/station doors

WARNING

1.) Sensitive electronics and high voltage inside the ozone generator box. KEEP OUT!*

2.) Do not open doors until the LED light has turned GREEN.

3.) As with other cleaning procedures, stay away from the cart/station during disinfecting cycle.

*The ozone generator box is tamper-sealed. Opening the box will void the warranty/service agreement of this unit.

Essential CleanZone Information

Ozone is a powerful agent for disinfecting. Below are some questions and answers you might find useful.

Yes, ozone has a somewhat familiar smell. When you are outside, right before a thunderstorm and particularly right after a lightning strike, that “pungent,” “electronic,” or even “clean” scent is ozone. This smell is the result of the electrical current splitting up the oxygen molecules. The fragrance (along with the gas) quickly dissipates and naturally converts back into oxygen.

The CleanZone system is programmed to run within the factory-installed, contained space inside our specific carts/stations. It generates only enough ozone for the particular interior volume of the cart/station where it has been installed. The system circulates the ozone gas inside the cart—you will hear the fan’s sound during each cycle—sanitizing all surfaces it contacts. Ozone is produced for a very brief time (less than two minutes), then it begins to dissipate very quickly. Given the volume of the space within the cart or station and the “contained” nature of its operation, the extent of any potential exterior exposure is minimal and falls safely within OSHA guidelines. Also, ozone is heavier than air, so after the decontaminating cycle is completed and the cart/station doors are opened, any residual ozone gas remaining will spill onto the floor and dissipate at ground level almost instantly.

NOTE: Be sure to fully close and lock all the cart or station doors before beginning the decontamination cycle.

NOTE: Do not open the cart or station doors at any time while the LED indicator light is RED.

NOTE: We recommend users—especially those that may be more sensitive to smells or suffer from any respiratory-related issues—maintain a minimum distance of six feet from the CleanZone system during the cleaning cycle.

In the CleanZone system, ozone is only generated for a few moments at the start of the cleaning cycle. The ozone is contained within the cart/station enclosure to prevent ozone levels outside the cart/station from reaching levels high enough to be considered hazardous to users. The cart or station’s door(s) need to be closed and locked before initiating the decontamination process. Once the cycle is complete, the ozone dissipates very quickly and becomes oxygen again. Testing has shown that the entire sterilization cycle lasts approximately 15 minutes. When the LED light turns GREEN again, it’s safe to open the doors and access devices.

As an added precaution, we recommend users—especially those who may be more sensitive to smells or suffer from any respiratory-related issues—maintain a minimum distance of six feet from the CleanZone system during each cleaning cycle.

Decontamination is quick: Once the ozone generator is activated, sanitizing will be completed within a 15-minute cycle. Ozone is generated only during the first few moments of the process—the remainder of the generation cycle allows the ozone to be distributed throughout the contained space until it naturally decomposes and dissipates back into oxygen. When the LED indicator turns GREEN, the cart/station door may be opened to access the sanitized devices.

Do NOT open the doors of the cart or station when the LED is RED.

The generator box below is held in place at the top of the cart/station. Each one has been designed and configured for the specific volume of space within our carts/stations. Please do not tamper with the box.*

Ozone has been used safely for years as a highly effective disinfectant. Ozone targets microorganisms and destroys them on contact. The FDA, USDA, and EPA have approved ozone as an antimicrobial disinfectant. It’s 3,000 times faster and 50% more potent than chlorine/bleach. Ozone kills many types of bacteria and even the common cold virus, leaving no chemical residue. Tests have also shown ozone kills 99.9% of pathogens on contact.

Any further questions related to ozone as a disinfectant is on our CleanZone page.
