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 Ingersoll-Rand 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.
