6.3 Replacing the terminal box or capacitor
Fig. 22 Terminal box
If the terminal box is replaced, make certain the elec-
trical information listed on the new box matches the
information listed on the old box, and that it is com-
patible with the pump and incoming electrical supply.
For all terminal boxes, it is very important to tightly
secure the frame grounding screw through the termi-
nal box, so that a proper connection between the ter-
minal box and motor is made.
