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 plastic enclosure, the LCD display
and Front Panel buttons, 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.
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.

Metal Seal Care
CAUTION Metal Seals must be replaced during routine maintenance or
during any maintenance procedure required. All fasteners must
be installed and torqued per assembly procedure specifications.
Remove Metal Seals carefully with your fingers. Do not use
metal tools for this task, this prevents scratching of any sealing
surfaces. Wear non-powdered, ESD safe Nitride or equivalent
gloves prior to removing or replacing Metal Seals.
❑All Metal Seals come in clean room condition packages. No
cleaning is required If necessary, Metal Seals can be cleaned
using alcohol or methanol. Wipe all Metal Seals 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 Metal Seals that
will come in contact with the spectrometer.
