High-Pressure Water System Safety
Never work on any high-pressure component or loosen any high-pressure fittings without first bleeding
the system to ensure that there is no high-pressure water present. Follow all instructions and safety
recommendations in this manual.
WARNING
Always avoid contact with the stream of water. Seek immediate surgical attention
if you are exposed to any high-pressure stream of fluid.
•Avoid contact with the high-pressure water. HP water can penetrate any part of the human body and
cause severe infection or death if not treated properly. Seek immediate surgical attention if you
come in contact with any high pressure stream of fluid.
•Do not try to repair a leak on any HP water fitting when the system is pressurized. A leak at a
sealing surface can cause a hazardous spray of water. Shut off the motor and verify the HP water
pressure is relieved down the drain before servicing any high-pressure plumbing.
•Plumbing supports and guides must be used for all HP tubing exiting the pump. Failure to do so can
introduce excessive bending stress and fatigue through vibration causing premature failure of the
plumbing, and heighten risk of personal injury due to an unexpected rupture.
•Always use two wrenches when tightening or loosening HP connections: one for the gland nut and
one for the fitting. This will prevent excessive bending stress and premature failure of the
plumbing.
•Always use high-pressure piping rated for the type of system you are operating. This pump is
capable of outputting 60,000 psi of water.
Hydraulic System Safety
WARNING
Pressurized fluid streams can penetrate skin, causing severe personal injury or
death. If any fluid is ejected against the skin, seek immediate surgical attention.
•Make sure all connections are properly tightened after performing service or maintenance.
•Keep hands and body away from pinholes and nozzles, which eject fluids under high pressure.
•Never check for hydraulic leaks with your hand: use a piece of cardboard or other material.
•Do not expose skin to a pressurized leak.
•Wear appropriate protective equipment including heavy gloves and safety glasses.
•Do not attempt to tighten or loosen any mechanical connection unless the machine is powered off
and all system pressure has been relieved.

Motor/Pump Assembly Safety
WARNING
Beware of moving equipment. Keep clothing and hands away from equipment that
is operating. Always verify covers and shields are in place before starting
equipment.
2.4 Emergency Medical Treatment
Waterjet equipment can cause severe injury and infection. Anytime a person comes in contact with a
high pressure stream of fluid, it must be reported immediately and treated. It may look as though
nothing happened, but a serious infection and possible amputation may result if immediate surgical
attention is not received.
Always seek immediate surgical attention if you come in contact with any high pressure stream of fluid.
Failure to do so can result in severe infection.
The injury should be treated as an acute surgical emergency and be evaluated by a qualified surgeon.
Circulation may be compromised therefore DO NOT apply heat. Keep effected person awake and
elevate injured part.
Inform the medical personnel that the victim has been working with a high-pressure mixture of water
and abrasives at up to 60,000 psi and a nozzle velocity of up to 2,000 feet per second. Waterjet injuries
have been known to cause infections with micro-Europhilic organisms such as gram-negative pathogens
like those found in sewage.
9

Emergency medical information
Anyone who receives equipment related injuries while operating high-pressure water equipment
should be given immediate hospital attention. It is vital that waterjet operators carry a waterproof
emergency medical tag or card that describes their work and the nature of injuries inherent in using
waterjet cutting devices.
This card provides general purpose information to aid in relaying information to medical or emergency
personnel.
MEDICAL ALERT

3.2 Utility Requirements
Site Preparation
WARNING
Certain locations may be hazardous if the atmosphere contains gas, vapors, or
dust in explosive quantities. Refer to the National Electric Code (NEC), IEC, OSHA
requirements, and local codes for detailed information about environmental
criteria.
The facility must have adequate air, water, sewer drain, and electrical service per the Specifications
section prior to installation of the equipment.
Floor material should be concrete capable of supporting the weight of the machine, and thick enough to
provide resistance to vibration.
11

Water Requirements
IMPORTANT
Local codes may require that a back-
flow prevention valve be supplied to separate
the pump from the building potable water. Consult local codes for the required
type and necessity of a valve.
Cutting Water
The water supplied to the intensifier is a crucial factor in precision waterjet cutting because of its direct
effect on the service life of equipment components. The pump's built-in filtration is sufficient for
removal of suspended solids. Total Dissolved Solids (TDS) in the inlet water will have an adverse effect
on check valves, seals, orifices, and other consumables. Most systems require that the water be softened
at a minimum before it enters the pump.
Before installing the system have a water quality analysis performed by a local company that can
provide water-conditioning equipment. See the Inlet Cutting Water Requirements section under
Specifications for specific conditioning requirements.
Cooling Water (if supplied with a Water/Oil Heat Exchanger)
The heat exchanger uses regular tap water for cooling the hydraulic fluid. Hydraulic fluid temperature
must be maintained below 130ºF. The hydraulic cooling water section of the Specifications area of
this manual details the cooling water flow and temperature requirements.
In most cases public-utility water is acceptable. In situations where the water contains heavy mineral
deposits, the cooling fins in the heat exchanger may become clogged with buildup. In these
circumstances pre-filtration and/or softening may be necessary. Depending on plant setup, ambient
temperature can also be a factor in cooling. Where the equipment is confined to a small high-
temperature space, additional cooling may be required.
Sewer Requirements
The pump has two outlet lines. The WASTE WATER OUT line carries any rejected cut water from the
bleed-down valve. The COOLING OUT line carries the water exiting the heat exchanger in water
cooling units. DO NOT couple lines.
Both outlets require independent lines to the sewer drain to prevent exiting cooling water from backing
up into the system. The wastewater outlet plumbing must be lower than the outlet connection on the
pump. This will prevent potentially dirty water from backing into the bleed down valve causing closure
problems.
12

Electrical Requirements
CAUTION
When connecting power to the pump it is the buyer's responsibility to investigate
and comply with all local codes. The power requirements are listed on the serial
plate on the back of the pump as well as on the inside of the electrical enclosure
door.
Three phase power connection
Each of the three phases of input power are connected to the three (3) terminals at
the top of the motor switch (right). Additionally a ground leg must be attached to
the grounding lug inside the electrical cabinet.
Pumps equipped for certain foreign power may have slightly different connection
requirements. Always refer to the electrical schematic for the machine to verify
proper connection.
Schematics are supplied in the Drawings and Parts Listssection of the manual and
an additional copy is included inside the electrical cabinet.
Location Requirements
•The pump must be placed in a location, which allows access to all sides for service.
•The pump should have a minimum 36 in. clearance surrounding the machine, free of all obstacles,
to allow room for service. See the Pump Requirements section under Specifications.
•The pump should not be placed in any environment where the temperature is below freezing. If
freezing temperatures are expected before operating again, drain all water lines and filter housings
after work is completed for the day.
WARNING
If a water line, fitting, or valve may be frozen, DO NOT operate the machine. The
system must be thawed until water flows freely through the entire water circuit.
Recommended Tools
Most maintenance of the pump can be accomplished using standard tools. Refer to the recommended
tools list in the Drawings and Parts Lists section. Contact Hypertherm to purchase replacement
specialty tools for intensifier and bleed-down valve servicing.

4Operation
4.1 Operation Overview
This section outlines the operation of the Front Control Panel, as well as startup procedures, and normal
operation. The HyPrecision 100D/150D pumps are controlled from the front control panel.
The main disconnect on the electrical enclosure must be turned on in order for the pump to function.
4.2 Front Control Panel
The HyPrecision 100D/150D pumps are controlled via an Operator Control Station (OCS) attached to
the outside of the Electrical enclosure. The OCS monitors all fault conditions and controls the
intensification process. Certain pump models referred to as OEM may not have a control panel. In this
case, refer to the manual for the equipment that is controlling the pump.
The OCS is equipped with digital inputs and outputs for monitoring all pump and environmental
conditions as well as controlling the functions of the pump.
Other features include intensifier enable/disable, intensifier-overstroke threshold setup, and alarm
logging.
Log files are stored on a removable MicroSD card. When troubleshooting is necessary, the card can be
removed from the pump and the information transferred via a USB reader to Hypertherm technicians.
Program updates can also be installed by simply copying a new program onto the card and replacing it
in the pump.
No service is necessary on the OCS. All inputs and outputs run to terminal blocks, which should be used
for wiring the remote options. Refer to the supplemental control manual, for additional details about
control operation and features.
Standard Control Panel
Base model pumps have the standard control panel. The standard control panel
has an OCS panel, hydraulic gauge, cut pressure adjustment knob, and pierce
pressure adjustment knob. In addition, there are water gauges indicating the pre
and post filter water pressure.
The following image shows the standard control panel (all HyPrecision
100D/150D models).
CONTROLS ON: Enables the pump controls.
LOCAL/REMOTE KEYSWITCH: Switches from local pump control to
remote pump control. See Remote Pump Operation under the Operation
section in this manual.
EMERGENCY STOP: Shuts off controls, motors, and intensifiers, and bleeds
down the high-pressure water.
REMOTE ACTIVE light: Lit when pump is in remote pump control mode or
remote pressure control mode.
15

Depending on the type of pump model(s) you have the layout of the gauge panel will vary.
The PIERCE PRESSURE and CUT PRESSURE adjustment knobs, located on the gauge panel, are
manually operated.
Units with the optional analog pressure control will not have the CUT PRESSURE and PIERCE
PRESSURE control knobs, which are replaced with a high precision electrical control valve.
CUT PRESSURE knob (if applicable): Adjusts Pressure Set Point 1 (Cut). See Adjusting the Cut and
Pierce Pressure in the Operation section for more information.
PIERCE PRESSURE knob (if applicable): Adjusts Pressure Set Point 2 (Pierce). See Adjusting the
Cut and Pierce Pressurein the Operation section for more information.
HYDRAULIC PRESSURE gauge: Displays the hydraulic pressure of the pump. Pumps with more
than one hydraulic pump will have additional gauges. The hydraulic pressure gauge can be useful in
determining the approximate cut pressure. To do so, use the following formula:
Cut Pressure = 19.25 X Hydraulic Pressure
PRE-FILTER WATER PRESSURE gauge: Displays the water pressure before the filter bank. See
the Low-Pressure Water section of this manual for more information.
Normal operating range: 40-110PSI
POST-FILTER WATER PRESSURE gauge: Displays the water pressure after the filter bank. See the
Low-Pressure Water section of this manual for more information.
Normal operating range: 40-110PSI

4.3 Pump Startup
Initial or Post-Maintenance Startup
The first time you start up your pump it is important that the Pre-Startup Inspection, Motor Direction
Check, and First Time Startup procedures (below) be performed to prevent serious damage to the pump
components. Make sure that all installation requirements have been met prior to performing any of the
following checks. Follow all safety procedures as outlined in the Safety section of this manual.
It is common to identify leaks in the high-pressure water, low-pressure water, and possibly hydraulic
circuits while performing these procedures. Always stop the procedure and correct the leaks before
continuing.
Pre-Startup Inspection
1. Verify all safety circuits are connected and operational.
2. Check the sight gauge to make sure the hydraulic reservoir is full. Add oil as necessary to bring
the oil to an acceptable level. Refer to Hydraulic Oil in the Hydraulic section in this manual for
instructions on adding oil.
3. Verify all utilities are connected to the pump and turned on at the plant.
4. Check for loose hoses and fittings and make sure there are no leaks present.
Motor Direction Check
CAUTION
This procedure involves exposing a rotating shaft. Never place any object or any
part of your body near the shaft while exposed. Only visual inspection should be
used to prevent bodily injury. Be prepared to press the EMERGENCY STOP
button.
IMPORTANT
The motor direction check should be performed anytime electrical maintenance
has been performed on the electrical panel, motor wiring, or line wiring to the
pump. Improper motor rotation can cause irreversible damage to the hydraulic
pump and components.
1. Open or remove the front cover from the pump and locate the motor rotation arrow.
2. Remove the safety cover on the pump mount and visually inspect the coupling rotation.
3. To jog the motor, pull the EMERGENCY STOP button on the control panel, and then press the
CONTROLS ON button.
4. Press (COOLING MODE) and then press (PUMP OFF) to jog the motor. Verify
visually that the shaft is rotating the same way the motor rotation arrow indicates.
If the motor rotates in the wrong direction, swap two of the wires at the starter panel's MAIN
DISCONNECT, not at the motor or starter contactors, and then recheck the rotation. After verifying
motor rotation, replace the safety cover on the pump mount and the side covers. Also, see Motors in the
Electrical System section for additional information.
17

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.
