Operation Manual - SP 305

9. Be sure that the nitrogen bottle supply valve is

firmly closed. Attach the high-pressure regulator to
the nitrogen bottle; then attach the hose to the high-
pressure regulator. Finally, attach the other end of
the hose to the valve assembly gas valve stem, as
shown in Figure 43. Do not open the nitrogen
bottle supply valve yet.

10. Turn the regulated pressure adjustment handle on

the high-pressure regulator

counterclockwise

to its

minimum setting.

11. Crack open the nitrogen bottle supply valve

(Figure 44). You will get a reading on the high-
pressure gauge side of the regulator. Note that if
there is not at least 1500 PSI showing on the high
pressure regulator gauge at this time, you will not
be able to charge the nitrogen to the 1500 PSI
specification. If that is the case, you will need a
new bottle of nitrogen before proceeding. If there
is enough pressure in the nitrogen bottle to do the
job, proceed to step #14.

12. Adjust the regulator handle

clockwise

, raising the

regulated pressure. The accumulator will begin to
fill. Continue filling until the charge kit gauge
reads the desired pressure of 1500 PSI. Close the
nitrogen bottle supply valve.

13. If you overcharge the nitrogen pressure, proceed as

follows:
•

Close the nitrogen bottle supply valve.

•

Slowly

open the bleed valve on the charge kit.

Close the bleed valve when the correct
pressure is reached.

NOTE!

Never let nitrogen out of the accumulator by
pressing the gas valve pin with a foreign
object. The high pressure may rupture the
valve seat!

14. Let the nitrogen sit in the accumulator for 10 to 15

minutes. This allows the gas temperature to
stabilize. Recheck the pressure on the charge kit
gauge.
