Caution Note: If the second stage is leaking even slightly, IP will be affected. If
it is leaking, turn the adjustment knob to stop the flow or use a second stage that
is not leaking when paired with the first stage. It is a clear indication that the
second stage requires rebuilding if turning the adjustment knob does not stop
the flow.
(4) The standard operating range for the system is with an IP of 135 PSI. Ideally, the system is operating
at 135 PSI +/- 5 PSI and show no signs of “creep” or instability at 3000 PSI.
Caution Note: “Creep” will show as the IP steadily increasing while the regulator
is not in use. Normally the IP will drop 5-10 PSI during a breath or purge and then
return to its setting. It should not return to the setting and keep increasing. This
would indicate a problem with the High Pressure Seat, Piston, or sealing O-rings.
(5) If the system shows no sign of creep or IP instability, it is generally not necessary to rebuild the first
stage, with some exceptions.
Caution Note: If the unit shows signs of internal corrosion or the filter shows
evidence of contamination, the unit must be rebuilt, regardless of the IP.
(6) The regulator will require rebuilding if small bubbles are leaking from between the turret retainer
and main body, from under the rubber cap, or out of the high-pressure seat retainer. Knowledge of
flooding of the first stage will also require the unit to be rebuilt. Freshwater contains dissolved minerals
and other materials that, due to internal corrosion over time, may cause the regulator to malfunction.
(7) After the IP has been checked, hoses and regulator body inspected, and SPG evaluated, the service
of the first stage can take place if it is determined that service is necessary.
