Sears 390.30579 Haintenance, Grounding Outlet, Pump Minimum Watt Model Rating of Generator

ELECTRICAL / MAINTENANCE

Grounding Outlet

If your outlet is not grounded, install a copper wire, at least 14 gauge (2mmZ), from the outlet box, as shown in Figure 3B, 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 continu-

ity is interrupted by plastic, rubber, or other electrical insu- lators; 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 3C), with a length of No. 4 wire clamped securely at both ends.

Automatic Thermal Overload Protection

This pump motor has a built-in 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.

[_kWARNING] 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 non-operational surnp pump. Take it to Sears for service by a qualified technician.

Generator Sizing

Below is the minimum Engine-Generator Watt rating required
