Before doing any electrical work, make certain the power
is disconnected and properly tagged or locked off. All
electrical work must be done by a qualified technician
and meet all applicable codes. If it is necessary to make
troubleshooting checks inside the control box with the
power on, USE EXTREME CAUTION. Do not place your
fingers or non insulated tools inside the control box.
Touching wires or other parts inside the control box
could result in electrical shock, death or serious injury.
Never allow more than 130 volts to be connected to the
120 volt motor circuit. Damage to motor, push-button, air
bag, and serious personal injury or death may result.
