*1) The ultimate pressure is the value indicated on the Pirani gauge when the standard oil (ULVOIL
R-72) is used. The ultimate pressure when the McLeod gauge is used is approx. one digit
lower than the value indicated on the Pirani gauge.
*2) GP close: When the gas ballast port is closed GP open : When the gas ballast is fully opened
*3) The type of rotary pump oil differs depending on vapor pressure, viscosity, etc. The use of a
wrong type of oil can lower the pump performance. So use the pump oil recommended ULVAC.
recommended type of oil: (1) ULVOIL R-72 (standard oil), (2) ULVOIL R-42 (oil for use in
coldseason)
