The vacuum pump becomes hot (40-80ºC) during operation. Only touch the valve
when operating the gas ballast valve.
Always close the gas ballast valve before starting the pump.
If the gas ballast valve is left open when condensed gases are not being exhausted
from the pump, not only may pump oil be sprayed around and the power be reduced,
but the ultimate pressure will also be increased.
Close the gas ballast valve when condensed gases are not being exhausted from the
pump.

Attaching the oil mist trap (option) element
The OMT-100A, OMT-200A, OMI-100, and OMI-200 oil mist traps can be attached to
the GHD-101 to collect the exhausted oil mist. Attach an OMT-100A, OMT-200A,
OMI-100, or OMI-200 oil mist trap to the exhaust section instead of the standard
exhaust port. Attaching one of these oil mist tarps will prevent the oil mist from being
exhausted and also reduce the exhaust noise.
Refer to the oil mist trap instruction manual for details.
4.9
Operation restrictions when attaching the oil mist trap (option) element
The following operation restrictions apply when using an oil mist trap. Replace the
filter if it becomes clogged.
The internal pressure limit of this pump is 0.03 MPa (gauge pressure). If
measurement of the pump exhaust pressure shows a value of 0.03MPa (gauge
pressure), replace the oil mist trap filter.
Failure to follow this requirement may result in the pump breaking. Observe the
operation restrictions when using an oil mist trap. Replace the filter if it becomes
clogged.
