First Time Startup
IMPORTANT
The following first time startup procedure should be followed after any service has
been performed on the intensifier, high-pressure water, or low-pressure water
assemblies.
1. Make sure the cut pressure and pierce pressure adjustment knobs are backed out all the way. If
the pump has analog pressure control make sure the pressure setting is 10ksi or less.
The pump may have been shipped with loose fittings, filters, and components
depending on winterization requirements, where the pump is shipped to, and
other environmental factors. Make sure that all of the water fittings and loose
components are tightened before proceeding to the next step.
2. Prime the flow of the cutting water:
a. Disable the Intensifier.
b. Open the cutting head.
c. Turn the source water on.
d. Let sit for 2-3 minutes.
e. Depress the red button on the top of each of the filter housings to bleed air from the canisters.
f. Close the cutting head.
3. Start the pump by pressing the (PUMP ON) button on the touchscreen display. Make sure
that the boost pressure meets the inlet water requirements as outlined in the Specifications
section of this manual.
4. Check again for any leaks and loose fittings. Take any corrective action and then proceed to the
next step.
5. Flush the pump and high-pressure lines using the following procedure.
Flushing HP Water Lines
After installation of a new pump and high-pressure lines, it is common for small pieces of metal and
debris to be present in the high-pressure lines.
IMPORTANT
NEVER perform the initial startup with a diamond orifice in place. The likelihood of
damaging the orifice during the initial startup is very high!
It is important to flush the system to prevent damage to orifices, on/off valve
parts, and other parts of the HP system.
The following procedure describes one method to “flush out” the HP lines. If you purchased your
Hypertherm pump through an OEM, they may have their own procedure that they recommend. During
this procedure, damage may occur to the on/off valve sealing parts and orifices. Make sure to have spare
kits and orifices available before starting the procedure.
