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

5 .0 instructions for safe use

1 This equipment has been designed for the pressurisation

of sealed heating, chilled water and closed condenser

water systems to the operating conditions shown.

2 No installation of this equipment should take place until

this installation, operation and maintenance instructions

has been studied and understoodby the person

responsible.

3 Handling, transportation and installation of this equipment

shall only be undertaken with the proper use of lifting gear.

4 The set shall not be used for any purpose other than that

for which it was designed and sized.

The set shall not be operated with the cover

removed and the cover interlocked isolator

note:

During normal operation the pumps will only

generate pressures sufficient to satisfy system de-

mand. However, abnormal running conditions may

cause closed valve pressures to be experienced.
