22.
Position the poppet and seat assembly into the end of the valve body.
23.
Lubricate the threads on the valve body with Pure Goop and thread the pressure control
valve assembly into the high pressure manifold. Torque the valve body to 190 ft-lbs (258
Nm).
24.
Install the air and drain lines.
25.
Follow the startup procedure in Section 4, Operation, before returning the pump to
service.
5.8
Low Pressure Filter Maintenance
To ensure water quality and supply to the high pressure assembly, the filter elements will require
routine servicing and maintenance. The procedures for servicing these components are detailed
below.
The life of the filter element is directly related to the quality of the inlet water. The condition of
the filter element can be monitored by observing the post-filter pressure gauge on the control
display. The elements should be replaced when the pressure drops below 18 psi (1.2 bar) when
the pump is running.
Check the pressure gauge only when the pump is running at full speed and
operating at full output pressure. When the pump stops, the pressure will increase
substantially, even with a dirty filter.
1.
Shut the system down.
2.
Turn the supply water off.
3.
Using a strap wrench, remove the filter
housings.
4.
Remove the filter elements from the housings
and discard.
5.
Inspect the contents of the housings. This
inspection can provide early warning of a
change in supply water quality.
The fine and coarse elements must be installed in the correct position as labeled on
the pump. Failure to do so could shorten pump life.
