Do not put wires below the fan. If wires get pinched behind the fan,
this can cause damage to the wires and prevent the fan from operating
correctly.
To confirm you have the right fan, check the barcode sticker on the side of the fan.
Fans for 3-phase models have a 6-digit Hypertherm® part number (429225) on the sticker. Fans for
1-phase models have only the barcode on the sticker.
