Hazard and Safety Information
The common international symbols used in this manual and on the equipment are defined
below.
Operators and service personnel must be aware of all hazards associated with this
equipment. They must know how to recognize hazardous and potentially hazardous
conditions, and know how to avoid them. The consequences of unskilled, improper, or
careless operation of the equipment can be serious. Every operator or service person must
read and thoroughly understand operation/maintenance manuals and any additional
information provided by Agilent. All warning and cautions must be read carefully and
strictly observed. Consult local, state, and national agencies regarding specific requirements
and regulations. Address any safety, operation, and/or maintenance questions to your
nearest Agilent office.

Solvents
WARNING The mechanical components of leak detectors are typically
cleaned with alcohol, methanol, or other solvents.
When heated, sprayed, or exposed to high-temperature
equipment, these solvents become flammable and explosive,
causing serious injury or death. Do not use these solvents near
a high-temperature source. Ventilate the working area with a
blower and work in a large, well-ventilated room.
Alcohol, methanol, or other solvents are irritants, narcotics,
depressants and/or carcinogens. Their inhalation and/or
ingestion may produce serious side effects. Prolonged or
continued contact with the skin results in absorption through
the skin and moderate toxicity. Always ensure that cleaning
operations are carried out in large, well-ventilated rooms, and
wear eye shields, gloves, and protective clothing.
To clean the leak detector enclosure and the LCD display, use
only a soft cloth slightly dampened with water or a mild soap.
Do NOT use excess water or cleaning solvents of any kind.
Avoid splashing any cleaning solvents into the unit through the
ventilation openings. Wipe the surface with a dry lint-free cloth.
CAUTION Do not clean any aluminum parts with Alconox®. Alconox is
not compatible with aluminum and will cause damage.
Vacuum Equipment and Cleanliness
Cleanliness is vital when servicing the leak detector or any vacuum equipment. There are
some techniques that are more important in leak detector servicing than in general vacuum
work:
CAUTION Do not use silicone oil or silicone grease.
Use powder-free butyl or polycarbonate gloves to prevent skin
oils from getting on vacuum surfaces.
NOTE Agilent does not recommend the use of vacuum grease.
Vacuum grease absorbs helium tracer gas and releases this
slowly resulting in helium background during leak test
operations. If it must be used, use it sparingly and avoid
silicone types. Apiezon®L grease is recommended (Agilent Part
No. 695400004).

O-ring Care
When removing, checking or replacing O-rings, keep in mind the following:
NOTE Agilent recommends replacing all O-rings during routine
maintenance or during any maintenance procedure requiring
that O-rings be removed.
NOTE Due to the effective cleaning nature of VacuSolv solvent and
its residue-free properties, Agilent’ Component and
Spectrometer Cleaning Kit (Part Number 670029096), used in
accordance with the kit instructions, is recommended for
cleaning spectrometer components. The kit can also be used for
fine cleaning of other parts in the leak detector’s vacuum
system such as valves and fittings. No rinsing steps or
high-temperature drying are required following cleaning with
VacuSolv. Although appropriate precautions are advised,
VacuSolv is compatible with most materials and does not
contain toxic chemicals or CFCs (chlorofluorocarbons). Other
acceptable solvents are isopropyl alcohol (IPA) or Dow
Corning®OS-20.
CAUTION Remove O-rings carefully with your fingers. Do not use metal
tools for this task; this prevents scratching of any sealing
surfaces.
❑ Wipe all O-rings clean with a lint-free cloth before
installation to ensure that no foreign matter is present to
impair the seal.
❑ Do not use grease or any other substance on O-rings that
will come in contact with the spectrometer.
❑ Do not use alcohol, methanol or other solvents on O-rings.
Doing so causes deterioration and reduces their ability to
hold a vacuum.
❑ Agilent does not recommend the use of vacuum grease. If
applicable, apply a small amount of Apiezon®L grease and
wipe the O-rings shiny dry.

Equipment, General
Environment of intended use:
❑ Indoors use in an industrial and laboratory installation only.
❑ Altitude up to 2000m
❑ POLLUTION DEGREE 2, Overvoltage Category: I, Class III
(DC powered)
❑ Operating Temperature: +5 °C to +48 °C, Relative
Humidity (RH) up to 80% max. Operating in the top working
range of [-3, -4, -5, -6], avoid operating with a constant
foreline pressure > 500 mTorr at +48° C.
❑ Storage ambient conditions: RH from 0% to 95%,
non-condensing, temperature: -20°C to +60°C
WARNING ❑ Do not use in presence of flammable or explosive gas.
❑ Do not attempt to disassemble or modify the equipment.
Such action could lead to electric shock or injury. Agilent's
authorized technician will do any repair work.
❑ If there is smoke or unusual smell or noise, stop the using the
equipment immediately, and contact the Agilent Service
Center.
WARNING The leak detector is not designed for use with hazardous gases.
Verify that the system to be tested has been purged of all
hazardous gases prior to using the leak detector. When testing a
system that contained hazardous gases, connect the exhaust of
the leak detector to a scrubbed or toxic containment exhaust.
Exposure to hazardous gases could result in serious injury or
death.
WARNING Equipment tightness is guaranteed for normal operating
conditions when the equipment leaves the factory. It your
responsibility to maintain the level of tightness, particularly
when pumping dangerous products.
CAUTION The performance and operating safety of this equipment can
only be guaranteed if it is operated according to normal
conditions of use.
Allow at least 4" of clearance adjacent to the ventilation slots at
the front, sides and back of the equipment enclosure.
Allow sufficient room for the operator to safely maneuver to
perform testing.

LCD Display
WARNING If the LCD display breaks, avoid getting any liquid crystal in mouth
or eyes. If it gets on the operator hands, feet or clothing, wash it
immediately with soap and water.
CAUTION Do not apply excessive pressure to the LCD display as this may
cause smears.
In general, the lower the temperature, the longer it takes the LCD
display to turn on. Performance of the LCD display may deteriorate
in low temperature.
Power and Static Sensitivity
The power supply requirements for VS C15 Component leak detector: 24 VDC, 5 A min.
The VS Component leak detector can be ordered with or without an external 24 VDC
AC-DC power supply.
❑ When ordered with the universal external AC-DC power supply (VSC15PS), you
must provide a mains supply:
❑ 100-230 VAC ± 10%, 50/60 Hz ± 2%, with a 10 A local power switch/circuit
breaker.
❑ When ordered without the external power supply, you must supply a 24 VDC
+/- 5%, 5 A min. power supply with a local power switch.
Provide the 24 VDC power to the VS Component leak detector via a detachable cable: 18
AWG triple-twisted wires terminated by Molex’s HCS-125 Receptacle (P/N 03-12-1036),
with 3-socket female terminals (Molex P/N 18-12-1222) that are compatible with a DC inlet
connector of an EMI filter on the rear panel of the VS C15 Base Unit. Wire as follows:
❑ +24 VDC: position 1 (D-shape terminal) of the receptacle.
❑ PE wire: position 2 (middle terminal) of the receptacle; to provide grounding
between the VS C15 units and the external power supply system.
❑ 24VRTN wire: position 3 of the receptacle.

Figure 1 24VDC Input Power Connection
Provide the 24 VDC power to an optional VS C15 Display Unit via a High Density 15-pin
D-Sub M/F cable connected to the DISPLAY connector on the rear panel of the Base Unit as
shown below.
CAUTION Use surge protection to improve the immunity of the leak
detector against unidirectional transients caused by the
following phenomena:
❑ Switching phenomena in the power network
(e.g., switching of capacitor banks, inductive loads,
electrical motors, etc.)
❑ Faults in the power network
❑ Indirect lightning strokes
CAUTION Many components of the leak detector are static sensitive.
Wear a grounding device when performing any maintenance
on the leak detector, especially when performing maintenance
of static sensitive parts, such as circuit boards and the
spectrometer.
