H. Never discharge fuel gas from a cylinder valve near welding or cutting work,
sparks, fl ame, or any other possible source of ignition.
I. Before attaching regulator, remove any dirt or foreign matter that maybe in
the cylinder valve outlet by wiping with a clean, lint-free cloth. Valves on other than
combustible-gas cylinders may be opened momentarily to blow outlet clean.
J.
Never pressurize a regulator that has loose or damaged parts or is in questionable
condition. Never loosen a connection or attempt to remove a part until gas pressure has
been relieved. Under pressure, gas can dangerously propel a loose part.
K. Before transporting cylinders that are not secured on a cart designed for such
transport, remove regulators and recap the cylinders.
L. Keep cylinder handwheel or wrench on open cylinder valve at all times, for prompt
emergency shutoff.
M. Do not attempt to clean or change parts of oxygen gauge. Have regulator repaired
by Eutectic Corporation (see Section IV).
N. The regulator relief valve, if any, is designed to protect the regulator only, and
nothing else. Be sure that equipment connected to the regulator outlet is provided with
relief devices to protect such downstream equipment against possible overpressure.
O. Check regulator and ALL connections for leaks after installation, periodically
thereafter, and after any service in which parts or connections were loosened. Brush on
a soap solution of 1/4 oz. of liquid soap per gallon of water (2 milliliter). Bubbles indicate
leak.
P. No repair should ever be undertaken by anyone not having qualifi cations described
in Subsection 4.1.
I. INTRODUCTION
1.1 SCOPE
This manual provides general information for the installation, operation, and
service of Eutectic Tri-Safe
®
Model II Regulators.
1.2 USE
These regulators are designed to control and reduce high gas pressure from a
cylinder or pipeline, in one or two stages, to the working pressure required for
the equipment using it. Tri-Safe regulators are equipped with the following:
A. Large adjusting knob to control delivery pressure manually.
B. Two stage pressure regulation, with encapsulated valve seat mechanisms.
C. Standard CGA inlet and outlet connections.
