4 Operation
CAUTION
Edwards will accept no liability or warranty claims if your pump is used on applications or in a way prohibited
in this manual, or not specified in this manual.
4.1 Operational safety

Do not expose any part of your body to vacuum. If you do, you may be injured.

Do not operate the pump with the pump inlet or outlet ports open to the atmosphere. If you do, your fingers
or other parts of your body or clothing may get trapped, and you may be injured by the rotating mechanisms
in the pump.

During operation, parts of the HV8000 pump can become very hot. Ensure that you do not touch the pump.

Do not operate the pump with any guards removed from the pump drive shaft, the coupling/belt or the drive
system (where fitted). If you do, your fingers or other parts of your body or clothing may get trapped, and
you may be injured by the rotating components.

Never disconnect any of the connecting pipelines (for example, the pipeline connected to the inlet) when
the pump is operating.

Do not attempt to use the HV8000 pump to pump liquids. The HV8000 pumps are not designed for this
application.

Where necessary (for example, if you have not fitted an acoustic enclosure), wear suitable ear defenders.
The pump can be noisy during operation (refer to Section 2.9 ).
4.2 Start-up
4.2.1 Pre-start checks
1. Check that the oil-levels are correct (refer to Section 3.5 ) and that the oil filler-plugs are tightened.
2. Check that there are no visible oil or water leaks. If there are any leaks, contact your supplier or Edwards for
advice.
3. Check that the HV8000 pump is correctly installed, especially after initial installation and maintenance.
WARNING
Obey the safety instructions and precautions listed below. If you do not, there may be a risk of
injury or death to people, or damage to the pump.
WARNING
Ensure that the cooling-air flow around the pump motor is not restricted. If the air flow is
restricted, the motor will get hotter than normal during pump operation.
This may result in reduced reliability and/or damage and/or the risk of the thermistors/
thermostats, if fitted and connected, to shut down the system.
WARNING
Ensure that the correct grade of oil is used and that the oil-levels in the HV8000 pump are correct.
If an incorrect oil is used or if an oil-level is incorrect, pump performance may be affected and the
pump may be damaged.
