A4 Operation
The pumps are designed for continuous operation.
CAUTION
If the pump is stopped for any reason; the dry nitrogen supply to the regulators must be switched off. This
eliminates the need to reset the regulators and also prevents possible oil pump priming problems on re-start
when the system is under vacuum.
Note: Refer to Figure A3. If you wish to continue to purge the oil-box after the pump has stopped you need only
switch off the supply to the gas-ballast by closing the flow regulator (5) to the gas-ballast.
