Installation
DynaMAX 550P/560P/575P Waterjet Pump Operator Manual 811390 189
Requirements
Location
Install the pump on a solid, flat surface that can hold the weight of the equipment and is thick
enough to resist vibration.
Make sure that there is sufficient space for auxiliary equipment such as a water softener, a reverse
osmosis system, or a chiller.
Cooling
If the cooling water or the supply water temperature is higher than24°C(75°F), cool the water
before use. Water that is too warm can shorten high-pressure seal life.
WARNING
Some locations can be dangerous if the atmosphere contains explosive gas, vapors, or
dust.
Refer to requirements from the National Electric Code (NEC), the International
Electrotechnical Commission (IEC), the Occupational Safety and Health Administration
(OSHA), and other national and local codes for information about environmental criteria.
Do not install this equipment in an area where the temperature is below freezing. Freezing
can cause damage to the pump.
Make sure that there is a minimum clearance of91cm(36inches) on all sides of the
equipment. This lets air movement help cool the machine and keeps space available for
doing maintenance and repairs.
Hypertherm recommends installing the pump on a level surface with a difference in height
of no more than8cm(1/4inch) between opposite ends.
Do not use a glycol solution in a chiller at a concentration higher than 25%.
Glycol can be added to the cooling circuit to prevent freezing, but glycol is less efficient for
cooling than water.
Using a chiller with a water-glycol solution can have an effect on the performance of the
heat exchanger.
If this pump is installed in a small space or in a high-temperature location, consider adding
a chiller to the system for supplemental cooling.
