Replacing Air Pump in MP Series Ozone Generator

MP Series Technical Walkthroughs


This will be the same process to replace the air pump on the MP-1000, MP-3000, MP-5000 and MP-8000. Keep in mind, the MP-1000 will have a different air pump. Purchase the air pump here

  • To begin, remove the screws around the outer shell of the unit
  • Place the removed screws in a secure location, such as a bowl, to prevent them from being lost in the repair process
  • Next, remove the outer shell
  • This will expose the internal components of the unit
  • The air pump is located towards the bottom of the internal components
  • Flip the unit on its side
  • There will be four screws on the bottom
  • Remove the nut on the screws
  • It is a nylon insert nut
  • Place these additional screws in the bowl or other secure location
  • After removing these bottom screws, the air pump will be loose
  • Make sure to hold the air pump while removing the nuts as it could fall and be damaged
  • For non-repaired units, there will be a wire tie on the air pump wiring
  • Cut the tie so the wires are loose
  • There will be a bulkhead on the inside front of the unit
  • Loosen this bulkhead to release the air pump from the unit
  • The air pump can now be removed from the unit
  • Remove the nut from the end of the air pump
  • The air pump should now be held onto the unit by only the power cord
  • This last remaining cord will be plugged into the air compressor power switch located on the inside front of the unit
  • At this point, you can take a picture of the wiring to know where each goes later
  • Pull out the top two cords
  • The air pump is now uninstalled
  • Grab the new air pump and attach the wires to the connectors
  • If you are following along in the video, the white will go on the left and black will go on the right
  • Next, line the feet of the air pump up with the holes on the bottom of the unit where the previous air pump was held
  • Turn the unit on its side while holding the air pump in place
  • Fasten the nuts to secure the air pump in its position
  • Make sure the are snug because a loose air pump will create a rattling sound within the unit
  • Turn the unit back over
  • If you have zip ties, we recommend securing the wires
  • This will ensure they are controlled within the unit
  • Make sure the zip tie is snug, but not too tight
  • The wires should be able to move on their own
  • Cut off the excess zip tie
  • Take the nut that was on the bulkhead on the inside of the unit and connect it to the tube of the new air pump
  • Thread it down to place the end of it on the bulkhead
  • Once the bulkhead is fitted, tighten this nut back up
  • The repair has now been completed
  • Replace the shell to make sure the new air pump is functioning properly inside the unit

When operating an ozone generator, please remember to remove people, pets, and plants from the area. Be sure to leave the area being treated immediately and only return once the ozone has dissipated. Under most conditions, the treated area should be safe to return to 30 minutes to 1 hour after the unit stops producing ozone. Treated spaces or buildings should be well-ventilated prior to re-entry.

In case of accidental leakage of ozone, keep the ozone generator in a 
well- ventilated area. 
Ozone generators emit ozone. Do not inhale ozone. 
Ozone generators generate high voltage. 
Our ozone generators are designed and distributed by A2Z Ozone, Inc. in Louisville, Kentucky USA. EPA Est.: 95432-KY-1. Produced and made in China.
