PRECAUTIONS (MAINTENANCE & USE) (continued)
Ensure that the locking device of the fresh
gas outlet is in its fully retracted position,
thus properly securing the fresh gas hose
fitting.
The oxygen flow control valve is set to deliver
a minimum O
flow of 150 (±50) ml/min
2
(unless an additional air gas circuit is
selected). Thus, to prevent waste or depletion
of the oxygen supply, ensure that the System
Power switch is in the "STANDBY" position
when the machine is not in use.
The NARKOMED 3 shall only be used in con-
junction with a functioning oxygen analyzer
and breathing pressure monitor. In addition,

appropriate
respirometer
recommended.
Patient Breathing System:
The NARKOMED 3 patient breathing system
shall not be used in conjunction with any
additional components that establish a flow
direction.
DO NOT pinch or kink the fresh gas hose
leading from the fresh gas common outlet to
the absorber.
CAUTIONS
Anesthesia Machine:
Due to the weight of the NARKOMED 3, the
anesthesia machine should only be moved by
people who are physically capable of the task.
It is recommended that two people move the
anesthesia machine to aid in maneuverability
on inclines, around corners, and over raised
thresholds (i.e., elevators).
When moving the NARKOMED 3, remove all
monitors and equipment from the top shelf,
remove the absorber system, and use only the
handles provided. Take care when crossing
thresholds and moving up or down ramps.

Refer any servicing to qualified service
personnel.
Devices plugged into the anesthesia machine's
convenience receptacles contribute to the
anesthesia system's total leakage current. This
total leakage current shall not exceed 100 µA.
Unless the unit is specifically modified to
eliminate the minimum oxygen flow, the flow of
oxygen cannot be totally shut off using the
oxygen flow control valve. Do not force the
oxygen flow control knob over the end stop of the
valve.

To ensure that gas supplies are at adequate
pressure, pipeline pressure gauges should
indicate steady pressures of 50-55 psi.
To ensure that the backup battery is in a
continuously ready state, a successful Battery
Test (i.e., "Battery Test" green indicator
illuminates) should be performed prior to each
anesthesia procedure.
To test for erroneous flow indications due to
a lodged flowmeter float, the individual flow
control valves should be opened and closed in
a manner sufficient to demonstrate the free
movement of each float up and down the full
range of its respective flowmeter tube.
To avoid leakage of anesthetic vapors into the
operating room atmosphere, the vaporizer
filler valves (Figs. 9 & 10) should be tightened
(turned fully clockwise). Vaporizer drain
valves should also be tightened fully
clockwise.
Although designed to minimize the effects of
ambient radio-frequency interference, the
functioning of the NARKOMED 3 may be ad-
