Make sure power is disconnected from the A/C unit before installation.

Maximum ambient temperature in which the device shall be used is 130°F/55°C.

The ion emitters must be at least 2 inches away from any metal surfaces.

Never touch ion emitters while operating, static shock may occur.

Find the right location
  • Airlock™ should be installed proximal to the AC intake airflow, to ensure that the airflow passes directly through the ion emitters (brushes).
  • Airlock™ can be installed in any direction—upright, upside down, or sideways.
  • The ideal mounting location is in front of the AC filter and coils (cooling fins). However, we understand that sometimes this may not be feasible due to the boat's design and construction. If it cannot be installed in front of the AC filter, ensure that the device is located as close to the AC intake airflow as possible.
  • Ensure the ion emitters (brushes) will be at least 2″ away from any metal surface or wires to prevent interference or damage.
Mount the device
  • Airlock™ can be mounted in 2 different ways. Every boat is different, so we encourage you to use the one that suits your needs best.
  • The Metal Mounting Plate began being included with our devices on May 23rd, 2024. If your device does not include a Metal Mounting Plate and you need one because you cannot use the screws for installation, please contact us at
Option A) Metal Mounting Plate
  • Clean the surface where you want to attach the metal mounting plate. Ensure the surface is free from humidity, dust, grease, and oil.
  • Separate the metal mounting plate from the magnets.
  • Peel off the red liner to expose the adhesive and firmly press the plate onto the cleaned surface for at least 10 seconds.
  • Wait for 10 minutes to allow the adhesive to bond properly.
  • Bring the Airlock™ device close to the mounting plate and let the magnets attract to it.
Option B) Screws
  • Firmly secure the device using the included self-drilling screws. The device can be installed either vertically or horizontally, based on your preference and needs.
  • When attaching the device to a grille or screen, nylon ties may be used.
  • The ion emitters/brushes should not touch any metal surface or wires. Move and secure any wires that may come in contact with the ion emitters/brushes.
Connect the wires to a power source
  • Ensure power is off.
  • Ensure the power source matches the 100-240VAC voltage requirement.
  • Connect the red (live) wire and the black (neutral) wire to a constant power source on the AC circuit board.
  • A handy approach is to connect Airlock™ directly to the fan's power source. This configuration ensures that ions are generated only when necessary.
Turn on the power supply
  • Verify the device is secured and correctly wired.
  • Turn on the power supply. A purple LED indicator will illuminate constantly when the device is working properly.
  • To verify output, take a non-contact voltage reader and place it near the ion emitters/brushes it should indicate voltage.
  • Airlock™ can remain powered at all times.
