1. Unplug the system, remove the set screw on the back of the case and pull the machine out using the handles on either side of the fans.
2. Lift off the sheet metal cover from the top of the housing. You may see ash particles accumulated on the floor of the housing and on the reactor pads. The amount of ash you see will be a clear indication of how hard your machine has had to work. Don’t worry, the ash is harmless to you. It is simply all that is left of the pathogens that have been killed.
3. If you don’t see any ash or loose particles inside the metal housing—there isn’t much build-up so you’re almost finished—skip to Step 7! 
4. Remove the three metal-framed reactor pads, as well as the pre-filter from the system. Using a hair dryer or compressed air—blow the ash and debris off of these four pieces. The pre-filter will only have trapped dust, pet hair, etc. The bacteria, viruses and other pathogens are small enough pass through the pre-filter, only to meet their death in the reactor pads and UV light chambers.
5. Next, blow the accumulated ash out of the interior of the housing.
6. Put the reactor pads and pre-filter back into their slots. Be sure the metal screens of the reactor pads are facing towards the front of the system where the fans are; likewise, make sure the airflow indication arrow on the pre-filter is pointing toward the fans at the front of the system.
7. Replace the sheet metal cover onto the housing. Make sure the edges of the cover are on the outside of the housing and that it is pushed as far toward the front (fan side) of the system as it can go.
8. Return the system to the case and replace the set screw.

1. Perform monthly maintenance steps 1-6.
2. Put on sunglasses that are rated to block UV-C rays. DO NOT ATTEMPT THIS STEP WITHOUT PROPERLY RATED EYEWEAR.
3. Plug in the system. Briefly depress and release the kill switch located at the top of the fan mounting board. Doing this will send power to the lamps, allowing you to make sure they are still working. If both lamps illuminate, you’re finished! Return to steps 7 & 8 of the monthly maintenance and you’re finished. If one or both of the lamps do not illuminate, call PathoControl for replacement lamps. Most lamps last 12-15 months or more, but it is still a good idea to check them.

Once every year (from your date of first operation), your reactor pads, pre-filter and UVC lamps need to be replaced. Your system comes with a One Year Warranty for parts & labor, and a Renewable One Year Warranty for all other non-maintenance parts. The required maintenance items are: reactor pads, pre-filter and UVC lamps.

When you purchase the PathoControl Annual Maintenance Bundle for your system before your current year warranty expires, you will receive new replacement reactor pads, pre-filter, lamps and another full year of warranty (for all other machine parts).

PathoControl is committed to helping you make your machine last a lifetime. We will help facilitate its longevity by sending monthly maintenance reminders to the email address you used when making your purchase. We will also notify you via email when your annual maintenance is due.
