This service manual contains service, maintenance
and parts information for the Push-To-SetTM Intermittent
Suction Unit (PTS-ISU)
3.1 Description
2.1
North American (ANSI) Vacuum
Regulator
Note: Part numbers given are for Vacuum Regulators
without fittings or adapters/probes.
WARNING: Do not use this device in the presence of flammable anesthetics. Static charges
may not dissipate and possible explosion hazard exists in the presence of these agents.
The PTS-ISU is a dual purpose vacuum regulator
which provides either intermittent or continuous suction. It can be used for NG drainage (intermittent) or
pharyngeal/tracheal (continuous) suctioning throughout
the hospital.
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 first be pushed and then turned to set
vacuum levels.
Figure 1: PTS-ISU
8700-1251-900
Each unit contains a dual spring regulator module to
regulate and adjust suction which is precise in the critical care range (0-200 mmHg/26.7 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.

3/Description/Specifications
(3.1 Description Continued)
During use, as the flow requirement increases, the
valve automatically opens to maintain suction at the
preset level. Conversely, when the flow 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/Operation
4.1 Equipment Setup
Locking Gland Fitting
Insert the adapter/probe into the vacuum wall outlet. If
the regulator is mounted elsewhere, connect a vacuum
supply hose between the regulator’s adapter/probe
and the wall outlet.
WARNING: Connection to pressure sources,
even momentarily, could injure the patient or
operator and damage the equipment.
Use hospital-supplied suction tubing between the vacuum regulator and the collection container, and
between the patient port of the collection container and
the patient (minimum inside diameter is 6 mm[0.25 in]).
An Ohio Medical Hydrophobic Filter or Hydrophilic
Filter and Overflow Safety Trap (OST) should be used
between the collection container and regulator to prevent contamination of the regulator, wall outlet and
pipeline system.
ISO 10079-3 (BS 7259: Part 2, section 5.1.2) states
that “the usable volume of the collection container shall
not be less than 500 ml.”

oxide, parts should be quarantined in a well
ventilated area to allow dissipation of residual
ethylene oxide gas absorbed by the material.
Follow ETO processor’s recommendation for
specific aeration periods required.
CAUTION: Do not steam autoclave or liquid sterilize the PTS-ISU. Severe impairment to the operation of the regulator will result.
CAUTION: Disinfection with ethylene oxide mixtures may cause crazing (minute superficial cracking) of some plastic parts.
Note: The PTS-ISU should only be disinfected if it is
contaminated or maintenance is to be performed.
1. The regulator should be disinfected with the mode
selector switch in the |O|O (INT) position.
2. Ethylene oxide mixtures can be used at temperatures of 125 to 135°F (52-57°C ). If this temperature
cannot be obtained, room temperature sterilization
with 100% ethylene oxide can also be used.
Disinfection is NOT recommended as a frequent
procedure.
3. After each disinfection check the condition of the
internal filters. Replace any shrunken filters before
returning the regulator to service.
4. Perform Service Checkout Procedure (Section 8).

9.1 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 qualified
service personnel.
WARNING: Clean and disinfect all suction
equipment if contaminated before disassembly
to ensure service personnel are not exposed to
hazardous contamination.
PTS-ISU should be kept in use or used on a rotating
basis. Internal parts of unused equipment may tend to
deteriorate.
Maintenance of the vacuum piping system is as important as maintenance of the suction equipment. The use
of collection canisters with reliable shut-off valves,
Overflow Safety Trap assemblies and disposable suction filters will protect the regulator, wall outlet, and piping system. The flow rate at the wall outlet should be
checked on a yearly basis and suitable cleaning of the
outlets should be performed as needed. The flow rate
measurement should meet NFPA99 and/or ISO standards.
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, fittings 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.
4. Check that the high flow disposable suction filter 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 floats in the Overflow Protection Device
and collection canister for correct operation.
7. Perform the Pre-Use Checkout Procedure.
9.2 Recommended Maintenance
