*Ultimate pressure is measured by Pirani gauge.
|
|
1.
|
Oil is deteriorated with operating, and becomes the factor of performance shortage.
A decrease and the dirt of oil are confirmed, and please regularly add and replace it.
|
|
2.
|
A backflow preventer is incorporated into the pump to prevent the oil from flowing back while the pump is stopped.
Please make a suction side into atmospheric pressure when the pump is stopped for a long time.
|
|
3.
|
If operation is performed at high pressure, oil mist is generated at the exhaust side.
|
|
4.
|
It is not suitable for the pump if operation is performed continuously at a high evacuation pressure of 10kPa or more.
|
|
5.
|
There is a risk of explosion. Never block the outlet or operate the pump with equipment mounted at the outlet side that blocks the passage of gas.
Otherwise, the internal pump pressure increases causing the pump to explode, the oil level gauge to protrude or the motor to be overloaded.
|
|
6.
|
This motor houses an automatic returning thermal protector, which may be activated in case of trouble.
The motor will restart automatically when the temperature goes down.
If the thermal protector is activated, switch off the power immediately for safety reason.
