2.0 preface
1 The 3750 Pulpress pressurisation unit has been designed
for ease of setting and operation
2 All packaged pump systems are pre-wired and fully tested,
both hydraulically and electrically, prior to dispatch.
3 All parameter data has been entered into the controller
in accordance with the system criteria. Once on-site
connections have been made, and all pre-checks carried
out, the system is ready for commissioning.
4 During commissioning if system conditions are found
to vary from those set out in the design criteria, the
parameters can be easily changed
