Important Electrical Information:

The motor supports 115/230 V, 50/60 Hz operation, but this pump is supplied configured for 230 V single-phase power.

Please verify your local voltage, frequency and electrical connection before switching on the pump. Voltage conversion or motor wiring changes should only be performed by a qualified electrician in accordance with the Edwards operating manual.

The pump uses an IEC C14 power inlet. Please contact us before ordering if you require a particular mains cable or plug configuration.

Important Operating Information:

This is an oil-sealed vacuum pump and must contain the correct quantity and type of vacuum pump oil before operation.
The pump must remain upright during installation, transportation and use.
Install the pump in a sufficiently ventilated location.
Do not block the pump exhaust.
Install the oil-mist filter and exhaust line correctly before operation.
Do not operate the pump with oxygen-rich, flammable, explosive, highly corrosive or otherwise hazardous gases unless the complete system has been professionally designed and approved for that application.
Ultimate pressure depends on oil condition, operating mode, system cleanliness, gas load and vacuum-system configuration.
Please confirm process and chemical compatibility before purchasing.
