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
prior to dispatch.
3 If ordered with system criteria, all parameter data has
been entered into the controller in accordingly. 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 parame-
ters can be easily changed.

5.0 safety instruction
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 This equipment should not be installed until operation and
maintenance instructions has been studied and under-
stood by the person(s) responsible.
3 Handling, transportation and installation of this equip-
ment shall only be undertaken with the use of appropriate
lifting gear.
4 The set shall not be used for any purpose other than that
for which it was designed and sized.
5 The set shall not be operated with the cover removed and
the cover interlocked isolator overridden.
note
During normal operation, the pumps will only gen-
erate pressures sucient to satisfy system demand.
However, abnormal running conditions may cause
closed valve pressures to be experienced.
