Operation - Agilent Technologies HS-16 Instruction Manual

Operation

During initial installation, the newly installed pump fluid
may be subjected to degassing. This may result in foreline
pressure fluctuations that are considered normal.
WARNINGS
The following conditions increase the
risk of explosion:
❑
Air leaks into the system
❑
Roughing through a hot
diffusion pump, which can
cause hot hydrocarbon fluids
to ignite or explode when
exposed to air
❑
Air release or the admission of
air to a pump with a hot boiler
(permitting a strong oxidizer to
contact the hot pump fluid)
❑
Pressure above 1 milliTorr
(1.3X10
❑
Insufficient (or low level of)
pump fluid
❑
Operating a pump without
circulating cool water to the
main body cooling coils
❑
Operating pump with water
trapped in Quick Cool coil
❑
Foreign matter in the pumping
fluid, which changes its viscosity
and obstructs flow passages

CAUTIONS
❑
Do not turn on the heater without
fluid in the pump. This may ruin
the heaters and damage the pump.
❑
Do not air-release the pump while
the boiler is hot. Most diffusion pump
fluids break down under these
conditions.
❑
Do not operate the pump heater
unless cooling water is circulating.
Doing so causes the pump and fluid
to overheat.
❑
Do not operate without a foreline
baffle. This can cause a greater than
normal fluid loss. *The HS-32 does
not have a foreline baffle.
