1.2.1 Solvents
Warning The mechanical components of leak detectors may be cleaned with one
of the recommended solvents. When heated, sprayed, or exposed to
high-temperature e uipment, 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.
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.
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 is re uired 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.
To clean the leak detector plastic top enclosure, the LCD display and
front panels, 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 or Front Panel buttons. Wipe the surface with a dry
lint-free cloth.
1.2.2 acuum Equipment and Cleanliness
Caution

loves to prevent
skin oils from getting on spectrometer internal components.

acuum Products Division
Manual 699910005, Hot Ion Source Replacement Page 4
1.2.3 O-ring Care
When removing, checking, or replacing O-rings, keep in mind the following:
NOTE
Agilent recommends replacing all O
-
rings durin
g routine maintenance or
during any maintenance procedure re uiring that O-rings be removed.
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 vacuum surfaces.
• 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.
1.2.4 Metal Seal Care
CAUTION
Metal Seals must be replaced any time a spectrometer is opened. All
fasteners must be installed and tor ued per assembly procedure
specifications. Remove Metal Seals carefully with your fingers or a soft
tool. Metal tools scratch sealing surfaces.
• Metal Seals are supplied in pre-cleaned condition. No cleaning is
re uired. If necessary, Metal Seals can be cleaned using the
recommended solvents. Wipe Metal Seals clean with a lint-free
cloth before installation to ensure that no foreign matter impairs
the seal.
• Do not use grease or any other substance on Metal Seals that
will come in contact with the spectrometer.

acuum Products Division
Manual 699910005, Hot Ion Source Replacement Page 5
1.2.5 Spectrometer
CAUTION Store the Ion Source/Preamplifier sub-assembly in a cool, dry area in a
tightly sealed, ESD protected container. Wear non-powdered, ESD-safe
Nitride or e uivalent gloves when handling the spectrometer. Wash
hands thoroughly after handling the spectrometer filaments and
especially before smoking or eating.
The spectrometer and PCB’s are static sensitive devices. Wear a
grounding strap when performing any maintenance on these units and
especially when performing maintenance of static sensitive parts.
CAUTION The spectrometer operates at a very high vacuum produced by the high
vacuum turbomolecular pump. Service of the spectrometer re uires that
this vacuum be vented to the atmosphere.
