PREPARATION FOR USE
Place the External Cylinder on the
Weight Scale Platform on the rear of
the RR750X.
Connect the four hoses to the External
Cylinder as shown in Figure 1.
NOTE:
Color standards for cylinder valve
knobs were changed by the
manufacturer during 1992.
Therefore, do not depend on color to
indicate liquid or vapor valves on the
External Cylinder. Look for
“LIQUID” or “VAPOR” embossed
on the knobs.
Tighten fittings FINGER-TIGHT only. Over tightening may cause damage to the fittings or valves
and result in leaks.
It is recommended that ALL connections be checked with an electronic leak detector each time hoses
are reconnected.
