Field Repair Instructions Jetstream/Xstream – Intermediate pressure and cracking pressure
If repairs have to be performed in an environment where test equipment recommended in the service
manual isn't available, the following equipment and methods can be used when setting the
intermediate pressure of the 1

Equipment.

The following equipment is needed:

A tank of compressed air, with a minimum pressure of 180 bar / 2610 psi.

Adjustment tool with Poseidon article number 2705.

Allen Key 1,5 mm with Poseidon article number 2706.

Allen key 5 mm.

A low pressure gauge (0-10 bar / 0 – 145 psi minimum) that can be attached to a 1
pressure port.

A bucket of water, at least 4 inches deep


Make sure all other ports are blinded.

Open the tank valve and pressurize the regulator.

Check the low pressure gauge to see what the intermediate pressure is.

If needed, use the 5 mm Allen key to turn the adjustment screw of the 1
intermediate pressure reaches 8,5 bar / 123 psi. Purge the 2
process.

When an intermediate pressure of 8,5 bar / 123 psi has been set, check the low pressure
gauge to make sure the pressure isn't increasing or decreasing.

If the intermediate pressure remains stable at 8,5 bar / 123 psi, the intermediate pressure has
been set.
