Please note that all new Zontec PA 2500 machines are supplied with a Spor-Ax Air Filter(s), which are
installed on the back panel. Spor-Ax antimicrobial air filters provide a broad range of control for many
molds, mildews, algae, and bacterium present in the environment. The FDA, USDA and EPA have
approved this antimicrobial.
OPERATING INSTRUCTIONS
DO NOT TURN ON THE MACHINE. FIRST, UNPACK THE MACHINE AND TAKE THE PACKAGING
ENVELOPE OUT AND INSTALL THE CERAMIC PLATES AND FUSES.
1. Remove the 6 screws (2 screws from each side and 2 screws on top) and lift the cover off the
machine. Make sure that the unit is UNPLUGGED and time is on “AUTO”.
2. Remove the packaging located inside the unit and carefully unwrap. You will find the ceramic
plates, fuses and fuse holders inside.
3. Before you install the ceramic plates, lift up and remove the 4 plastic dust protectors that are
located at the back end of the plates (closer to the fans). Carefully pry open the titanium bracket
and slide the ceramic plates back in between the titanium plate brackets (they will fit snugly).
When the ceramic plates “bottom out” in the bracket, they are fully installed. Make sure that they
slide into the slot on the bottom. Once you have all plates installed, replace the 4 dust protectors.
4. Place the .200 fuses into the (2) fuse holders on each side labeled .200 amp and insert the large
fuse holder (2 amp) into the middle of the fuse housings on the back of the unit.

5. Turn the OZONE setting to “HIGH”. This knob controls the ozone output; the higher the numbers,
the greater ozone output.
*NOTE: If you are in a high humidity area, you will need to keep your machine’s output
running higher than in a dry climate.
6. Plug the machine in and press the timer manual button to “ON” and make sure that the green
lights in front of the machine come on. If so, immediately press the manual button back to
“AUTO”.
*NOTE: Your timer should indicate “AUTO” at all times. If the machine does not have either
of the two green lights on, refer to the troubleshooting section of this manual. *NOTE: the green
lights are indication lights. “Green” means that the machine is functioning properly.
“Unlit” means that the machine is not functioning properly. There are 2 lights, and each
one is an indicator. One for the left side and the other is an indicator for the right side of
the machine.
*NOTE: if a machine does not have the green light on, that means that a fuse has blown on the
machine, which is a good indication that the ceramic plates need to be changed or that the
machine needs to be changed. If it is close to the 6-12 month period for maintenance, we suggest
that you order your maintenance kits. The machine will not blow out ozone when the plates are
worn out. It will only blow out air.
WARNING! Make sure that the machines are unplugged when putting parts in (fuses, plates,
filters, etc.). Always run machines in unoccupied spaces. Prolonged exposure to ozone could be
harmful to your health.

MAINTENANCE
1. Open the top of the machine to clean. Remove the 6 screws (2 from each side and 2 screws on
top) and lift the cover off the machine.
2. Lift the dust protector straight up and remove and take the ceramic plates out. Before you take
the ceramic plates out, lift up and remove the 4 plastic dust protectors that are located at the back
end of the plates (closer to the fans) and remove the 4 ceramic plates from the machine.
*NOTE: set dust protectors aside and after you clean the plates inside the machine.
Reinstall them by sliding them back onto the slot that they were removed from on the back
of the plate holder.
3. The ceramic plates should be replaced every 6-12 months or as necessary, depending on
frequency of use. Cleaning the machine is very important to its lifespan and efficiency. After
continuous use and as a course of normal wear, the ceramic plates will develop microscopic
holes, compromising the integrity of the machine due to the buildup of contaminants inside the
machine, especially on the brackets and plates. In order for the machines to create a true “corona
discharge”, which creates the output of the ozone, the following parts must be free from debris
and corrosion and should be cleaned for changed out each time during your scheduled
maintenance.
*NOTE: Change out the white ceramic plates and throw away old plates. The ceramic
plates must be replaced. Throw the plates out that are in the machine. Do not keep them.
They will get mixed up with the new plates. Similar to batteries, you do not want to replace
only a few plates and keep a few of the old plates inside the machine.

*NOTE: Clean the titanium plates. The titanium plates must be cleaned every 6-12 months.
They look like stainless steel piece of metal on each side of the bracket.
*NOTE: Clean inside the titanium plates that hold the ceramic plates. Cleaning between the
plastic titanium plate brackets that hold ceramic requires complete attention. Be careful
not to spread the titanium bracket holders not too far because they will snap due to their
glass/plastic alloy.
4. The air filters are used to filter debris away from the ceramic plates and keep the machine clean.
The filters should be changed every 6-12 months. Simply lift out the filter holders and replace the
filters. Model PA 2500 has 2 filters, both which are located on the rear panel, one on each side of
the machine.
5. After cleaning the machine thoroughly, reinstall the plates and put back the dust protectors.
Replace the screws in the machine and test the machine. Carefully pry open the titanium bracket
and slide the ceramic plates back in between the titanium plate brackets and make sure they
“bottom out”. Once you have all plates installed, replace the dust protectors to their positions in
the brackets.
- To test the machine, plug the machine in and press the timer manual button to “ON” and make
sure that the green lights in front of the machine come on. If so, immediately press the manual
button back to “AUTO”. Your timer should indicate “AUTO” at all times.

- If the machine does not have either of the two green lights on, refer to the troubleshooting section
of this manual.
6. Check for the “corona” discharge” in front of the machine. When the 2 green lights on the front
(face) of the PA 2500 are lit, this means that the electrical output is constant. To verify that you
are getting the maximum output of ozone, periodically examine the front of your machine. You
should see a vertical “black light” line that is straight with no spotting, sparking, waves, or arcing.
If this is not the case, then this indicates that the titanium plates need to be cleaned again.(If you
cannot see the black light, plug the machine in a darker area of the room). If you see the straight
line, then your machine is running at optimum performance.
TROUBLESHOOTING
If either of the 2 green lights is not lit, this indicates that the ceramic plate on that side of the machine has
a microscopic hole in it and will continue to blow the fuse. We recommend replacing the .200 fuse on the
unlit side of the unit, and all 4 plates. This will restore the maximum ozone output and protect the
machine. Replace only the fuse that is currently blown out at this time.
When the 2 green lights on the front (face) of the PA2500 are lit, this indicates that the electrical output is
constant but to verify that you are getting the maximum output of ozone, periodically examine inside the
machines. You should see a vertical “black light” line that is straight with no waves or arching, if this is not
the case then this is an indication that the titanium plates need to be cleaned again. Refer back to Step 4
of the MAINTENANCE section.
