Utilities
Electrical power
The motor size determines the full load amperes, the overload settings, and the wire sizes. Refer to
your pump model (beginning on page 138 in this section) or to the electrical drawings.
The electrical drawings are shipped in an envelope that is found inside the electrical
cabinet.
The pump uses 3-phase alternating current (AC) electricity. Some parts, such as valve solenoids
and sensors, use24-volt direct current (VDC) electricity from a power supply in the electrical
enclosure.
Supply water
Softened water is necessary for most systems. Get advice from a specialist for recommendations
for choosing a water treatment system. Reverse osmosis systems are available from Hypertherm.
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.
Cooling
Compressed air
Do not use deionized water unless the system has stainless steel water fittings.
Deionized water can cause the plumbing parts to fail.
