Power Requirements
The customer must provide the power cable for the water-muffler pump. The pumps provided by Hypertherm take a
three-phase input. Part numbers and corresponding voltages are listed below. Input current information is provided
on the motor data plate. Present pump systems all draw less than 20 amps. Select cable sizes accordingly.

Air Requirements
Provide a clean, dry, oil-free source of air with a delivery pressure between 80 and 120 psi (5.5 and 8.3 bar) with a
minimum flow rate of 20 scfm.
For further information, please refer to Hypertherm water muffler instruction manual (801730).
Initial Height Sensing (IHS)
The customer must provide a source of compressed air to the Initial Height Sensing system.
Air Requirements
Use a clean, dry, oil-free source of air to prevent possible problems created by moisture and water in the line.
Reduce shop air pressure to 20 psi (1.4 bar) with a regulator. Use a 1/4 inch I.D. hose between the regulator and
the inductive height control module.
An option to the IHS system is an upper-limit switch and cable. Please refer to Initial Height Sensing Connections
in the Installation section of this manual for further information.
