Installing the Transmitter on a High Pressure Hose Extension

WARNING

Always use the pre-installed flow restrictor when using the transmitter directly attached to your regulator (Installing the Transmitter on Your Tank Regulator). Always use the included air spool when connecting the transmitter to a high pressure hose extension. Using the transmitter without either the flow restrictor or air spool could result in serious injury or death from an air pressurization failure.

Before you install the transmitter on a high pressure hose extension certified to the EN 250:2014 standard, you should read the transmitter position tips and choose a position that provides the best line of sight to the dive computer.

To install the transmitter, you need two 5/8 in. (16 mm) open-ended wrenches and a small flat screwdriver or flat-nose pliers.

The transmitter can connect to a high pressure hose extension from the high pressure output port of the first-stage regulator.

  1. Use a screwdriver or pliers to carefully remove the flow restrictor Callout number one from the transmitter.

  3. Confirm the regulator is depressurized and detached from a scuba cylinder.
  4. Remove the port plug from the high pressure output port of the first-stage regulator.
  5. Connect a high pressure hose extension to the high pressure output port of the first-stage regulator.
  6. Screw the transmitter onto the high pressure hose extension until you feel resistance.

    WARNING

    Verify the installed transmitter does not physically interfere with any hoses or other tank assemblies.

  7. Use two 5/8 in. (16 mm) wrenches to tighten the transmitter, placing one wrench on the transmitter and one wrench on the hose fitting.

    NOTICE

    To prevent damage to the transmitter and possible loss of function, do not overtighten. Do not use the transmitter housing to tighten or loosen the transmitter.

    Do not grip the regulator or the transmitter to move, carry, or adjust the tank.

  8. Ensure the connection between the transmitter and hose fitting is secure before using the device.

You must remove the air spool and reinstall the flow restrictor before installing the transmitter on your tank regulator.
