Installation and Operation
WARNING: Not for inhalation. Does not
support life. For use with powered surgical
devices only.
Research and experience have shown that water-
pumped dry nitrogen is the ideal source for
pneumatically-powered surgical instruments.
Water-pumped dry nitrogen is 99.97% pure, and
will not support combustion or corrosion.
Compressed dry nitrogen is recommended as the
pneumatic power source. It is available in
standard cylinders.
Compressed dry nitrogen must meet the
following specifications to ensure optimum
safety for both patient and instrument.
Nitrogen Content:
99.97% pure, dry nitrogen.
Quality Assurance:
To obtain the quality of gas
needed, “water-pumped dry nitrogen, or liquid
nitrogen, pumped dry” should be specified.
Nitrogen is readily available from gas supply
houses in
H
cylinders holding slightly more than
300 cubic feet (8.50 cubic meters). Initial set-up
costs are relatively inexpensive as compared to
compressed air. Nitrogen can be placed in the
operating room or in a storage area and piped
into the operating room. Manifold systems are
available to eliminate frequent tank changes.
CAUTION:
Do not exceed 100 psi
(7 kg/cm
2
) operating pressure unless a hose
longer than the standard 10 ft. Universal
Hose (5052-010) or extension hose is used.
Add an additional 1 psi for every extra foot of
hose.
The Series 4 handpieces should be operated
at 100 psi (7 kg/cm
2
) for maximum operating
efficiency, and should be monitored by the
operating pressure gauge of the regulator.
Lower pressure setting can be set for lower
speed and torque requirements. Pressure
must be set with the instrument running to
ensure proper operating pressure.
Never start a procedure if the operating
pressure gauge indicates less than 500 psi
(35.1 kg/cm
2
) in the tank. Never run the tank
pressure below 200 psi (14.0 kg/cm
2
).
The tank should be thoroughly wiped off with
disinfectant and draped prior to placement in
the operating room. Always have the tank
securely fastened to a stable object.
1.
Prior to set-up in the operating room, open
the tank valve (counterclockwise) slowly
and allow enough gas to escape to blow out
any debris that may have accumulated in
the valve. Stay clear of the opening and the
back of the tank during this procedure.
Return the valve to the closed position.
