HT4001
Instruction Manual
Power Cable from HT4001 Power Supplies to Power Source
1. The line disconnect switch must be in the OFF position!
2. Connect the power cable leads to the line disconnect switch following local and applicable electrical codes.
Optional Equipment
Water Muffler
The water table provides the supply of water for the water-muffler pump. This water must be filtered for the
water-muffler system. Hypertherm provides a filter (027009) with all water-muffler systems.
Important: Place the pump as close as possible to the water table. Longer distances result in pump priming and
water lag problems during start up. This results in excessive noise and smoke during the initial
starting.
Plumbing Requirements
Attach the filter to the pump with approximately four feet of 3/4 inch I.D. #12 hose. The customer may supply
his/her own water pump and water hose or purchase a pump with or without hose through Hypertherm. Please
refer to water muffler system part numbers listed on the following page, and water muffler instruction manual
801730 for further information.
Torch Lifter Requirement
The HT4001 system requires a high-quality, motorized torch lifter with sufficient travel to cover all cutting thickness
requirements. The lifter must provide at least 10 inches (254 mm) of vertical travel. The unit must have a
constant speed of at least 20 ipm (508 mm/min) with positive braking. A unit which drifts through the stop point is
not acceptable.
WARNING
The line disconnect switch must remain in the OFF position during the rest of the pre-installation and
installation of the HT4001 system!
