Installing the Transceiver on a High Pressure Hose Extension
Always use the pre-installed flow restrictor when using the transceiver directly attached to your regulator (Installing the Transceiver on Your Tank Regulator). Always use the included air spool when connecting the transceiver to a high pressure hose extension. Using the transceiver without either the flow restrictor or air spool could result in serious injury or death from an air pressurization failure.
Before you install the transceiver on a high pressure hose extension certified to the EN 250:2014 standard, you should read the transceiver position tips and choose a position that provides the best line of sight to the watch (Transceiver Position Tips).
To install the transceiver, you need an open-ended wrench and a small flat screwdriver or flat-nose pliers.
-
Use a screwdriver or pliers to carefully remove the flow restrictor from the transceiver.
Use care when removing the flow restrictor to avoid damaging the device.
-
Insert the large end of the air spool into the transceiver.
-
Detach the first-stage regulator from the scuba cylinder and second-stage regulator.
-
Screw the transceiver onto the high pressure hose extension until you feel resistance.
Verify the installed transceiver does not physically interfere with any hoses or other tank assemblies.
-
Use an open-ended wrench to tighten the transceiver until it is secure.
To prevent damage to the transceiver and possible loss of function, do not overtighten. Do not grip the regulator or the transceiver to move, carry, or adjust the tank.
You must remove the air spool and reinstall the flow restrictor before installing the transceiver on your tank regulator.
