Always connect the regulator to the vacuum
source and check its operation before attaching
the patient connection.
Do not use this device in the presence of flam-
mable anesthetics. Static charges may not
dissipate and possible explosion hazard exists
in the presence of these agents.
Following sterilization with ethylene oxide,
parts should be quarantined in a well ventilated
area to allow dissipation of residual ethylene
oxide gas absorbed by the material. Follow
sterilizer manufacturer’s recommendations for
specific aeration periods required.
For proper Posi-Pulse operation, the Posi-Pulse
ISU’s “On” and “Off” timing cycles must be a
minimum of 10 seconds.
If the flow control valve is rotated fully clock-
wise, the ISU and Posi-Pulse ISU will not cycle
in the intermittent mode. Drainage will cease.

1/Precautions
1.3 Cautions
A supply vacuum of less than 15 in Hg/51 kPa
(380 mm Hg) may impair Posi-Pulse ISU and
Posi-Pulse Device operation.
Cleaning the gauge may result in damage.
Do not lubricate any internal components of the
regulator module.
Do not over-tighten the timing valve stem.
Needle portion of the valve may be damaged.
Do not steam autoclave or liquid sterilize the
ISU or Posi-Pulse ISU. Severe impairment to the
operation of the regulator will result. The only
acceptable method of sterilization is with gas
(ethylene oxide).
Do not use any 1Loctite® products to seal the
fitting and adapter port threads (or products
which contain Methacrylate Ester as an active
ingredient).
Only competent individuals trained in the repair
of this equipment should attempt to service it.
Sterilization with ethylene oxide mixtures may
cause crazing (minute superficial cracking) of
some plastic parts. Crazing will be more pro-
nounced when mixtures containing 2Freon® are
used.
The cap screws can strip the regulator module
housing threads if they are screwed in too tight.
The gauge assembly must be handled with
utmost care to retain its precision. If the lens is
removed, do not rest the gauge on its face.
To help prevent aspirate from entering the
regulator, an Overflow Safety Trap should be
attached prior to its use. Aspirate in the regula-
tor will impair the operation. The use of the
Overflow Safety Trap will help prevent this and
extend the life of the suction equipment.
To prevent stripping the plastic threads, place
the screw in the hole and turn counterclockwise
until it drops into the original threads. Tighten
screw.
Use of lubricants other than recommended, may
degrade plastic or rubber components.

A change in the intermittent mode flow rate is
rarely needed. If there is a desire to change the
factory set flow rate, perform the following
procedure.
1. Connect the supply vacuum to the adapter
port.
2. Pull the Ohmeda nameplate wrench from
the front of the regulator to access the flow
control valve.
3. Occlude the regulator fitting port.
4. Turn the mode selector knob to | (CONT).
5. Set 120 mm Hg/16 kPa on the regulator
gauge.
6. Turn the mode selector knob to O (OFF).
7. Connect the regulator fitting port to the
10 LPM flowmeter.
8. Turn the mode selector knob to |O|O|
(INTER) or |O|O| P-P (INTER).
9. Locate the flow control valve in the regula-
tor.
10. The flow rate must be adjusted during the
“On” cycle of the intermittent mode. Using
the proper tool, either a Phillips head
screwdriver or a ball hex key wrench, adjust
the flow control valve to produce a flow rate
of 8 LPM. To increase the flow rate turn the
valve counterclockwise. To decrease the
flow rate turn the valve clockwise.
