BOLD TYPE indicates maximum piercing parameters. BOLD ITALIC indicates edge starts only.
BOLD TYPE indicates maximum piercing parameters.
* Pressure of the water supply line should be regulated by customer pressure regulator.
Note 1: Ohmic height sensing is not recommended with water shield. Water on the plate interferes electrically with the ohmic sensing circuit.
Note 2: Water source used for shield must be demineralized.
