BONSAI® VELOCITY Conserver
NON-PORTABLE USE:
The BONSAI® VELOCITY conserver is designed to extend the life of portable oxygen
supplies when away from the primary source. While the BONSAI® VELOCITY conserver
may be used with stationary oxygen sources, the unit should be used only while awake
and reasonably attentive.
The BONSAI® VELOCITY conserver is not intended for use while asleep because, in the
unlikely event of operational malfunction or dislodging of the cannula, the user could be
unaware and not make the necessary corrections.

INSTALLING THE
BONSAI® VELOCITY:
STEP 1: Loosen the cylinder adjustment
handle.
STEP 2: Lower the BONSAI® VELOCITY
conserver over the Cylinder Post
Holes with the alignment pins toward
the holes on the cylinder neck
[see Fig. D].
STEP 3: Line-up the two pins and the seal
washer (gasket) with the corresponding
holes on the Cylinder Post Holes.
NOTE: The cylinder adjustment
handle should be aligned with
the indentation on the Cylinder
Post Holes.
STEP 4: While holding the unit in place, tighten
the cylinder adjustment handle by
turning clockwise [see Fig. D].
NOTE: Tighten only by hand.
The use of a tool to tighten the
handle may damage the unit.
STEP 5: Attach the cannula to the oxygen
supply outlet.

OPERATING
INSTRUCTIONS:
STEP 1: Make sure that the BONSAI® VELOCITY
conserver is set to the “OFF” position
before opening the cylinder valve.
STEP 2: To reduce the risk of rapid oxygen
recompression and fire, open the
cylinder valve slowly and completely so
the pressure gauge moves slowly as it
indicates the cylinder pressure.
STEP 3: Listen for leaks. If a leak is present, close
the cylinder valve, check the CGA 870
seal and re-install. If the leak continues,
DO NOT USE THE EQUIPMENT and
contact Drive Devilbiss (see below for
contact details) for further assistance.
STEP 4: Check the oxygen pressure gauge to
verify that the cylinder pressure is
within the operating range.
STEP 5: Select the setting on the BONSAI®
VELOCITY conserver to the appropriate
delivery setting [See Fig. E].
STEP 6: As with any nasal cannula, place the nasal
cannula into position with the prongs in
the nostrils and begin breathing.
The BONSAI® VELOCITY conserver will now start
to deliver oxygen. The amount of oxygen delivered
per pulse is determined by the setting. A sound
may be heard each time the unit delivers a pulse
of oxygen. Adequate saturation will be achieved
because of the precise time in the breathing cycle
in which the pulse of oxygen is delivered.
STEP 7: When finished using the system, close
the oxygen supply cylinder valve and
continue breathing through the nasal
cannula until no further oxygen is
detected and the gauge reads “empty”.
STEP 8: Remove the nasal cannula and turn the
selector switch to the “OFF” position.
STEP 9: When not in use, store in a clean,
dry location.
