Operating and storage conditions
Note:
For operation between -20 °C and 5 °C (-4 and 41 °F), we recommend that the HV8000 pump is operated
continuously except when shut-down is necessary for maintenance purposes. Note also the cooling-water
requirements given in
There is a wide range of backing pumps which are suitable for use with the HV8000 pumps. If necessary,
contact Edwards for advice.

WARNING
If you fit an isolation valve between the HV8000 pump and the backing pump, you must interlock
the operation of the valve with the operation of the HV8000 pump, so that closure of the valve
results in shut-down of the HV8000 pump.
