Low Pressure Water System

4-3
A temperature sensor, mounted on the outlet manifold, monitors the discharge temperature. To
reduce overheating during a deadhead condition, water is re-circulated through the orifice and
check valve, and routed back through the filter to the booster pump inlet.
From the outlet manifold, cutting water is routed to the sealing head inlet check valves on each
end of the intensifier.
4.5 Service and Maintenance Procedures
There are no routine service and maintenance procedures associated with the low pressure system
on base models. When pumps are equipped with the optional booster pump and low pressure
water filter, the filter element and booster pump will require routine servicing and maintenance.
NOTE
Refer to Section 11, Parts List for a complete listing of replacement parts and part
numbers.
Filter Assembly Maintenance
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 pressure gauge on the inlet manifold.
Document the pressure reading when the filter element is new. The element should be replaced
when the pressure drops to 15 psi (1 bar) below the original value.

1. Turn the cutting water supply off.
2. Press the red bleed valve on the filter head to release any pressure trapped inside the
housing.
3. Use a filter wrench to unscrew the housing and remove the old element.
