1.2 WARNINGS
Factory settings may be impacted during transport
therefore, the unit's timing cycle should be checked
prior to initial use and adjusted if necessary (see
Section 7.6 Timing Cycle Adjustment).
This device should be repaired only by qualied
Ohio Medical or Ohio Medical-trained, qualied
personnel, using only Ohio Medical recommended
parts. There are risks associated with using
anything other than Ohio Medical parts. Ohio
Medical will assume no responsibility for incidents
which may occur if the product was not repaired
in accordance with procedures authorized by Ohio
Medical.
If the vacuum regulator is repaired or disassembled
in any manner, the service checkout procedure
must be performed before using the equipment on
a patient.
After patient use, if regulator is contaminated then
handle in accordance with you hospital’s infection
control policy.
To reduce transportation personnel and/or service
personnel exposure to hazardous contamination,
DO NOT ship any suction equipment that has been
contaminated.
Do not use this device in the presence of ammable
anesthetics. Static charges may not dissipate and
a possible explosion hazard exists in the presence
of these agents.
Connection to positive pressure sources such as
oxygen and medical air, even momentarily, could
injure the patient or operator.
Ohio Medical will assume no responsibility for
incidents which may occur if the product is not
used in accordance with product labeling.
To help prevent aspirate from entering the device,
wall outlet and pipeline equipment, a safety trap
should be attached prior to its use. Aspirate in the
regulator, wall outlet and pipeline equipment may
impair its operations. The use of the safety trap
and suction lter will help prevent this and extend
the life of suction equipment.
1.3 CAUTION
Do not use any Loctite® products or any products
which contain Methacrylate Ester as an active
ingredient to seal the threads on the adapters/
probes and ttings.
Use of lubricants other than recommended may
degrade plastic or rubber components.
Do not steam autoclave or liquid sterilize the
regulator. Severe impairment to the operation
of the regulator will result. The only acceptable
method of sterilization is with gas (ethylene oxide).
Sterilization with ethylene oxide mixtures may
cause crazing (minute supercial cracking) of some
plastic parts. Crazing will be more pronounced
when mixtures containing Freon® are used.
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. Aerate parts for 8 hours
at 54°C (130°F). Follow your hospital sterilization
procedure.
Do not use harsh chemical or cleaning solution. Do
not spray cleaners directly onto suction regulators.
Only use chemical recommended in this manual.
If any evidence of damage is found, repair as
necessary or contact your authorized service
provider.
Connection to positive pressure sources such as
oxygen and medical air, even momentarily, could
damage the equipment.
The suction control knob must be completely pushed
in to adjust the vacuum level. Failure to do so may
damage the vacuum regulator.
Not for transport use: The categories of eld
and transport user are specically dened in
ISO 10079-3. “Field” means use at accidents
or emergencies outside a hospital. “Transport”
means use in ambulances, cars and airplanes.
These situations may expose the equipment to
uneven support, water, dirt, and mechanical shock
and temperature extremes. Ohio Medical Suction
equipment has not been tested to comply with the
specic requirements of these categories.
Note: Ohio Medical requests that parties acquiring
this device:
Report the device’s purchase, receipt in trade,
return after sale, loss, destruction, or retirement.

2/Scope 3/Description and Specications
This service manual contains service, maintenance
and parts information for the Push-To-SetTM Adult,
Pediatric and Neonatal Intermittent Suction Unit (PTS-
ISU)
2.1 ANSI Vacuum Regulator
(Analog/Digital)
Note: Part numbers given are for Vacuum Regulators
without ttings or adapters/probes.
2.2 ISO Vacuum Regulator
(Analog/Digital)
Note: Part numbers given are for Vacuum Regulators
without ttings or adapters/probes.
3.1 Description
A patented safety feature Push-To-Set™ (PTS)
automatically occludes the patient circuit as the desired
vacuum level is selected. It prevents higher than desired
vacuum levels from being accidentally delivered when
patient suctioning begins. The suction control knob must
rst be pushed and then turned to set vacuum levels.
Each unit contains a dual spring regulator module to
regulate and adjust suction which is precise in the
critical care range; Adult: 0-200 mmHg (0-26.7 kPa);
Pediatric: 0-135 mmHg (0-18.0 kPa); Neonatal: 0-100
mmHg (0-13.3 kPa) and quickly moves to full wall
vacuum for resuscitation. It requires only two turns from
zero to full wall vacuum. Each unit contains a vacuum
gauge, an ON/OFF switching module and adjustable
timing valves.
In use, the vacuum source is connected through the
regulator module which functions as an automatic valve.
Rotating the suction control knob adjusts the position
of the regulator module and selects a predetermined
level of suction.
During use, as the ow requirement increases, the
valve automatically opens to maintain suction at the
preset level. Conversely, when the ow requirement
decreases, the valve automatically closes to maintain
suction at the preset level. The same mechanism
compensates for changes in supply vacuum to
automatically maintain the pre-set suction level.

4/Cleaning, Disinfection and Sterilization
4.1 Cleaning and Disinfection
WARNING: After patient use, regulators may be
contaminated. Handle in accordance with
your hospital’s infection control policy.
CAUTION: Suctioned uids drawn into a vacuum
regulator do not stop in the regulator. They
proceed through it into the wall outlet and pipeline
system. Failure to clean and disinfect the wall
outlet and pipeline system may result in damage
to this equipment.
4.1.1 Routine Exterior Cleaning
Routine cleaning of the regulator is recommended as
a standard procedure after each use. Wipe all exterior
surfaces with a solution of water and mild detergent
and/or an approved cleaning solution.
4.1.1.1 Approved Cleaning Solutions
• Sodium Hypochlorite 0.5% (Bleach): Mixture of 13
. oz. of bleach to 1 gallon (128 . oz.) tap water
• Isopropyl Alcohol 70%
• Hydrogen Peroxide 3%
• Cavicide®Ready to use full strength
4.2 Sterilization
Should misuse occur, resulting in accidental ooding
of the regulator, the regulator may be sterilized using
Ethylene oxide (ETO). After sterilization, follow the
service checkout procedures (Section 7Service
Checkout Procedure).
WARNING: 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.
Aerate parts for 8 hours at 130°F (54°C).
Follow your hospital sterilization procedure.
CAUTION: Do not steam autoclave or liquid sterilize the
intermittent vacuum regulator. Severe impairment
to the operation of the regulator will result. The
only acceptable method of sterilization is with gas
(ethylene oxide).
CAUTION: Sterilization with ethylene oxide mixtures
may cause crazing (minute supercial cracking)
of some plastic parts. Crazing will be more
pronounced when mixtures containing Freon®
are used.
Note: The vacuum regulator should only be sterilized
if it is contaminated or maintenance is to be
performed.

6.5 Suction Level Limit Setting
(PED and NEO Models ONLY)
⚠ WARNING: This Low Vacuum Limit Setting
Procedure must be followed when repairing
Low Vacuum Regulators. Failure to do
this may result in suction exceeding the
prescribed level.
6.5.1 Vacuum Relief Valve
Adjustment
1. Remove the cover (see Section 6.2.1 Disassembly).
2. Connect the supply vacuum to the adapter/probe
port.
3. Connect an external vacuum test gauge to the
patient port.
4. Move the mode selector switch to | (CONT).
5. Slowly rotate the regulator module to increase the
vacuum level. Note the suction level at which the
relief valve opens. The relief valve should open at
140 mmHg ± 5 mmHg (18.7 kPa ± 0.7 kPa) on the
external test gauge.
6. If adjustment is required, grip the vacuum relief
valve rmly with pliers and rotate the screw about
1/8 turn with a screwdriver. Repeat the previous
step and check the suction level at which the valve
opens.
Note: Clockwise rotation will increase the suction
level at which the relief valve opens. Counter-
clockwise rotation will decrease it.
7. Lock the adjusting screw with a drop of removable
thread locker such as Loctite 242. Repeat step 5 to
verify the vacuum relief valve setting.
8. Re-attach the cover (see Section 6.2.2 Assembly).
WARNING: Excess Loctite®may seal the steel ball
to the seat. This will disable the vacuum
relief valve and may allow suction to exceed
the preset limit.
CAUTION: When Loctite is used on the vacuum
relief safety valve, ensure that it only contacts
the metal parts. Loctite causes many plastic
parts to deteriorate.
6.5.2 Vacuum Limiting Set Screw
Adjustment

8.1 General Maintenance of
Suction Equipment
WARNING: The Pre-use Checkout Procedure must
be performed before using this equipment on
each patient. If the regulator fails any part
of the Pre-use Checkout Procedure, it must
be removed from service and repaired by
qualied service personnel.
WARNING: If the unit has been contaminated,
clean and disinfect all suction equipment
before disassembly.
Protection of the vacuum piping system is as important
as maintenance of the suction equipment. The use
of collection canisters with reliable shut-o󰀨 valves,
overow safety trap assemblies and disposable suction
lters will protect the regulator, wall outlet, and piping
system.
Routine maintenance and inspection are important to
the performance of suction equipment. The following is
a recommended list for care of suction equipment after
each patient use.
1. Keep connecting tubing, ttings and adapters/
probes clean.
2. Wipe all exterior surfaces with a solution of water
and mild detergent or approved cleaning solutions.
3. Perform a careful visual inspection of the vacuum
regulator.
4. Check that the high ow disposable suction lter is
clean and in good condition.
5. Check that all tubing is in good condition and
connected securely to the correct ports.
6. Check the oats in the Overow Protection Device
and collection canister for correct operation.
7. Perform the Pre-use Checkout Procedure.

8.6 Installation Procedure for
Adapters/Probes and Fittings
CAUTION: Do not use any Loctite® products or any
products which contain Methacrylate Ester as an active
ingredient to seal the threads on the adapters/probes
and ttings.
All Ohio Medical regulators are supplied with 1/8”
NPT female ports. The standard port facilitates simple
adaptation to any quick disconnect system. Fittings
are available from Ohio Medical to adapt to your quick
connect system. We recommend you purchase the
appropriate ttings with your regulator at the time of
purchase. The ttings will then be factory installed prior
to shipping.
In the event that you must assemble or disassemble
ttings, please follow these instructions:
1. Prior to installing the ttings wrap the thread with
Teon tape Ohio Medical P/N 6700-1987-800 or
equivalent.
2. Apply appropriate torque 4.0 ft-lb (5.4 N-m)
minimum to 10.0 ft-lb (13.6 N-m) maximum.
3. Adapters/Probe and ttings which are not
keyed for specic orientation, should be torque
approximately 6.0 ft-lb (8.1 N-m).
4. Adapters/Probes and ttings that are keyed to
specic orientation, must be torque initially to 4.0
ft-lbs (5.4 N-m). Additional torque is applied only
until orientation is correct.
5. Make sure wall adapter is installed to specic
orientation so that they are mount straight on wall.
6. The regulator is now ready to place in service on
your suction system.
