Mount the speed adjust potentiometer through a 0.38 in. (10 mm) hole with the hardware provided

(see Figure 4). Install the circular insulating disk between the panel and the 10K ohm speed adjust

potentiometer.

Twist the speed adjust potentiometer wire to avoid picking up unwanted electrical noise. If speed

adjust potentiometer wires are longer than 18 in. (457 mm), use shielded cable. Keep speed adjust

potentiometer wires separate from power leads (BAT +, BAT -, A1, A2).
