Power Cable from Power Supply to Power Source.
1. Be certain that the line disconnect switch is in the OFF position.
2. Connect the power cord leads to the line disconnect switch following local and applicable electrical codes.
Optional Equipment
Water Muffler
The water table provides the supply of water to the Water Muffler pump. It is mandatory that this water be
filtered. A strainer filter, Hypertherm 027009, is provided with all Water Muffler systems.
Plumbing Requirements
Four feet of 3/4 inch I.D. #12 hosing is required to attach the filter to the pump. It is important that the pump
be placed as close as possible to the water table. Longer distances result in pump priming problems, as well
as water lag problems during start up. This results in excessive noise and smoke during the initial starting.
Water pump and water hosing can be purchased by the customer, or supplied by Hypertherm when ordering a
Water Muffler system. Please refer to Water Muffler System part numbers listed below, and Water Muffler
instruction manual 802050 for further information.
Torch Lifter Requirement
The system requires a high-quality, motorized torch lifter with sufficient travel to cover all cutting thickness
requirements. A lifter which provides 10 inches (254 mm) of vertical travel should be adequate. The unit
should have a constant speed of at least 20 ipm (508 mm/min) and braking should be positive. 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 system!
