Chapter 6  Power supply and electrical parts adjustment

DIP switches inside the control box

Wait at least 5 minutes after turning off the power switch and disconnecting the power cord from
the wall outlet before opening the face plate of the control box. Touching areas where high volt-
ages are present can result in severe injury.
