NOTE:
It is not necessary to perform this test unless a prob-
lem has been reported that requires diagnostic troubleshoot-
ing and repair. When performing routine overhaul service,
proceed directly to the following section,
Disassembly
.
1. Connect a calibrated intermediate pressure test gauge to the
regulator, either with a quick-disconnect inflator hose or with
the female fitting of a second stage LP hose, depending on the
connection of the test gauge.
CAUTION
: To provide a safety relief valve in the event that
intermediate pressure exceeds 155-170 psi, ensure that a fully
assembled and properly adjusted second stage is connected
to the first stage before pressurizing. Failure to relieve inter-
mediate pressure that exceeds 400 psi may result in damage
or rupture of the test gauge or LP hose, and could cause
serious personal injury.
2. Slowly open the supply valve to pressurize the first stage. Close-
ly monitor the IP test gauge to determine whether the interme-
diate pressure rises above 145 psi.
3. Note the intermediate pressure indicated by the test gauge, and
purge the second stage several times to determine whether
lockup is achieved without creeping or fluctuating back and
forth.
4. If the intermediate pressure creeps up or otherwise fluctuates
after cycling the regulator, wait for it to stabilize (if possible)
before making a final note of the intermediate pressure.
NOTE
: Correct intermediate pressure for the first stage is
140 (±5) psi, with an inlet pressure between 2,500 - 3,000 psi.
5. Close the supply valve and depress the second stage purge but-
ton to depressurize the system before attempting to perform any
disassembly.
