Install the 24 Volt Regulator, TO-220 Package

The 24 volt regulator (P/N TL783), U1, comes in a TO-220 package that looks like this

(there may be some variation in the plastic molding):

Install it with a heat sink, 6-32x3/8" screw

, and a keps nut following Figure 4. The

captive lock washer side should face the solder side of the PCB. Bend the leads down to

fit through the three holes in the PCB. Adjust everything so that it fits well. Tighten the

hardware, then solder the 3 leads.
