6.5 Installation procedure

Use this procedure to install or reinstall the system.
Procedure
1. Before installing the 682R Reservoir, inspect all
components for damage. If any of the components
are damaged, you should report this to your local
Flowserve representative. Refer to section 6.3.
2. Determine the installed position of the system. Refer to
the mounting requirements, section 6.4.1.
3. The 682R Reservoir shall not be moved by hand.
It is equipped with a lifting lug. Use an appropriate
lifting device to position the 682R Reservoir as close
as possible to the main equipment. Make sure you
leave sufficient room for operation and maintenance
purposes.

4. Make sure that the 682R Reservoir is installed in a rigid
support to counteract any vibrations and instability.

de-pressurizing the 682R Reservoir. The 682R
Reservoir might have energy stored inside. Make
sure that de-pressurizing happens slowly.
5. Connect the 682R Reservoir connections. Refer to

6.6. Transmitter and switch alarm set points

• The instrument alarm setting depends on the purpose
of the specific instrument (high alarm for Plan 52 and
low alarm for Plan 53A). A high level switch shall be set
to normally open (not detecting liquid), while a low level
switch shall be set to normally closed (detecting liquid).
• For the Plan 52 the pressure transmitter or pressure
switch shall provide a high-pressure alarm between 0.3
to 2.1 bar (5 to 30 psi). The alarm set point should be
below seal chamber pressure, typically less than
2.1 bar (30 psi).
• For the Plan 53A the pressure transmitter or pressure
switch shall provide a low-pressure alarm between 1.6
to 10.3 bar (24 to 150 psi). The alarm set point should
ensure the reservoir pressure is at least 1.4 bar (20 psi)
higher than seal chamber.
• For additional information on how to install or set alarm
points on the instrumentation, refer to the IOM specific
to the instrument.
