CONFORMITE EUROPEENNE - Comply with the EU "technical coordination and
standardization of new method" basic requirements of the directive.
WEEE - When the end user is going to discard the product must be sent to the appropriate
facilities, for recovery and recycling.
The direction of motor - Ensure that the pump-motor rotates in the correct direction.
1.2 Importance
WARNING
Operations not comply with the following protective measures will result in
significant personal injury and equipment trouble!
Be sure to turn off the power supply to execute the wiring and maintenance work. You are
recommended to install a dedicated Leak breaker. You have a risk of getting electrical shock in
case of failure or electric leakage.
Do not run the pump on blocking the exhaust outlet or putting any device that might hamper gas
passage onto the outlet. There is a risk that the pressure inside the vacuum pump will rise up to
cause break of the casing or the oil level gauge, resulting in overload of the motor. When utilizing
the oil mist trap perform the periodic maintenance so that no-resistance can be realized in
passage of gas.
Ensured pressure value of the pump is not over 0.03MPa (0.3kg/cm2) (gauge pressure). Check the
exhaust side pressure of the pump. If it was over 0.03MPa, take away anything in and around the
exhaust outlet that hampers gas passage.
Do not exhaust any hazardous gas such as explosive, combustible and toxic. If any toxic gas was
evacuated, not only the pump itself but also vacuum pump oil get toxic. Keep this in mind when
perform maintenance, ask the special agency to do the detoxification process.
Do not exhaust any gas which oxygen content is greater than atmospheric oxygen (the oxygen
content>21%) or other strong reactive gas.
The motor and pump become hot (temperature increase under non-load operation：40℃,
temperature increase under high-load 80℃)during operation, there is a risk of burns. Do not
touch the motor and pump during operation or soon after pump stopping. Apply an appropriate
protection to avoid touching the surface as necessary.
