4. Operation
4.1 Operational Precautions
(1) Do not operate the vacuum pump with any devices that cause
clogging of the exhaust attached on the exhaust port side in such a
way that they disturb the gas flow. Otherwise the inner pressure of
the vacuum pump may increase and cause a rupture of the casing
and the oil level gauge, resulting in oil leakage and an overload of
the electric motor.
(2) If the valve is installed in a pipe at the latter stage from the exhaust
port, check that it opens.
If toxic and combustible/flammable gases other than inactive gas are
discharged by the vacuum pump, it cannot be used since leakage may
occur from the pump body.
If combustible/flammable gas and materials other than inactive gas are
discharged by the vacuum pump, it cannot be used since
ignition/explosion may occur in the vacuum pump.
If toxic gas is sucked in the vacuum pump, it goes without saying that
not only the pump body but also the pump oil will be toxic. Take care
during the maintenance work.
