Grounding Outlet

If outlet is not grounded, install a copper wire (at least 14 gauge) from the outlet box, as shown in Figure 4, to a metal cold water pipe. Use ground clamp on pipe.

IMPORTANT: The cold water pipe you use as a ground must have metal continuity to electrical ground. If continuity

is interrupted by plastic, rubber, or other electrical insula- tors; such as hoses, fittings, washers or gaskets (including

water meter or pump), a metal bypass must be used. Any electrically insulated connector should be jumped (as shown in Figure 5), with a length of No. 4 wire clamped securely at both ends.

Automatic Thermal Overload Protection

This pump motor has a built:m automatic thermal overload

protector. If the motor overheats, the protector will open and cut off power to the motor before the heat damages it

internally. The overload will reset automatically and the pump will restart after the pump cools down below the dan- ger point.

IA WARNING]DO NOT attempt to work on the pump or

motor if the overload seems to have tripped. The motor may restart without warning at any time. You could be injured and the pump damaged if it starts when you are working on it.

DO NOT attempt to repair a sump pump. Take it to SEARS for service by a qualified technician.
