7.4 HP Dump Valve
The dump valve assembly includes a normally open HP water valve, plus
a solenoid operated air valve for the air actuator on the dump valve.
Replacement parts for the HP valve are provided in the Parts Lists
(Section 12, see Figure 12-7, “Bulkhead Piping Assy”).
7.5 HP Attenuator
There is no servicing of the HP attenuator at the customer level. The
seals in the HP attenuator are tested at KMT Waterjet to high pressure in
excess of operating pressure making disassembly difficult. In the event
of a HP water leak of a HP attenuator, the attenuator should be replaced.
The defective attenuator should be returned to KMT Waterjet for
replacement or servicing.
