Cylinder-Filling Procedures
Warning:
High pressure oxygen may present a hazard. Always follow proper operating
procedures, and open valves slowly. Rapid pressurization may result in personal
injury. Safety glasses and hearing protection are required when venting oxygen under
high pressure. The intended use of the
MOGS-100
is to fill large
K-type
cylinders.
The smaller M-type cylinder can then be trans-filled from the K-type cylinder.
Important:
Your
MOGS-100
unit is factory leak checked to insure trouble free operation. If any
external storage tanks or manifolds are installed, every installed fitting and connection
needs to be checked for leaks. Failure to ensure that there are no leaks in the system can
cause the system to run excessively due to wasted oxygen. This in turn will cause
premature wear on your machine.
Reserve Cylinders and Certification:
The system is shipped with a reserve bank of two (2) H/K sized (
244 ft
3
capacity) steel
cylinders, rated at 2200 psi (152 bar) . These are located on the back side of the control
panel and are used to trans-fill smaller D, E or M size cylinders in the blast containment
chamber. These cylinders come fully connected and leak checked and do not have to be
removed or serviced until they need to be re-certified. Department of Transportation (DOT)
recertification is required every five or ten years, depending on the previous certification.
The date of last certification is stamped on the collar of the cylinder (month and year only).
If a star symbol is stamped next to the date, re-certification is not required for ten (10) years.
If there is no star symbol then the cylinder must be re-certified after five (5) years.
These cylinders have an industry standard CGA 540 valve at the top. These valves are
normally open but can be closed by turning them fully clockwise.
Auxiliary External Oxygen Ports:
On the left side of the MOGS-100 cabinet (as you face the Control Panel) there are two
(2) ¼
”
NPT threaded ports.
Upper Port:
The upper port allows for bypassing the high pressure oxygen compressor inside the
MOGS-100
unit and delivering oxygen at
70 psi (4.8 bar)
directly to a clinic, hospital or
other low pressure oxygen demand. In order to use this option, the oxygen generator
needs to be set to automatic (on the touch screen) and the oxygen compressor inside the
machine must be manually switched to the OFF position. (It will normally be in the
AUTOMATIC Mode).
There is a three position switch on the control panel which is
accessible when the front access door of the machine is open. You cannot fill cylinders
and draw oxygen from the 70 psi (4.8 bar) port at the same time. A low output pressure
will result if this is attempted. If this capability is used
OGSI
recommends that an
additional oxygen storage tank be installed and located next to the left side of the cabinet.
MOGS-100 should use a 120 gal storage tank. See drawing on the following page for
suggested layout.
