TriScroll 300 Dry Scroll Vacuum Pump
WARNING
Disconnect power from the
TriScroll 300 before performing any
maintenance procedure.
Allow the pump to cool before perform-
ing any maintenance procedure.
Approximate cool-down time is one to
two hours.
CAUTION
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 alcohol, methanol or other
solvents on O-rings. To do so causes
deterioration and reduces their ability to
hold a vacuum.
If applicable, apply a small amount of
Krytox
®
GPL 224 grease and wipe the
O-rings “shiny” dry.
NOTE
Varian Vacuum Technologies recom-
mends replacing all O-rings during rou-
tine maintenance or during any
maintenance procedure requiring that
O-rings be removed.
Unless otherwise stated, apply
Loctite
®
242 or Loctite PST
®
567 to the
first few threads only. Apply just enough
to obtain a seal.
WARNING
The TriScroll 300 weighs 26.4 kg
(58 lbs). To avoid injury, use proper lift-
ing techniques when moving the pump.
