Installing the Transmitter on a High Pressure Hose Extension
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.
Inspect all o-rings before installing the transmitter, flow restrictor, or air spool, and verify they are clean and undamaged. Replace worn or damaged o-rings as needed.
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.
-
Use a screwdriver or pliers to carefully remove the flow restrictor from the transmitter.
Use care when removing the flow restrictor to avoid damaging the device.
-
Align the large end of the air
spool with the
transmitter, and slowly insert it straight into the transmitter with light
pressure.
When the air spool is properly aligned, it slides easily into the transmitter.
Do not force the air spool into the transmitter or install it at an angle. Improper installation could damage the o-ring and cause o-ring failure.
-
Screw the transmitter onto the high pressure hose extension until you feel resistance.
Verify the installed transmitter does not physically interfere with any hoses or other tank assemblies.
-
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.
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.
You must remove the air spool and reinstall the flow restrictor before installing the transmitter on your tank regulator.
