4)Plug the level control plug into a GFI receptacle, then plug the pump into the piggyback plug. One cycle of operation should be observed , so that any potential problems can be corrected.

5)It is recommended that the float should be set to insure that the sump well liquid level never drops below the top of the motor housing or a minimum level of 2.5" (64mm) above the pump bottom.

6.) Figure 3 shows a typical connection for pumps with the wide angle float and piggy-back plug. for manual and automatic operations.

C-4) Electrical Connections:

C-4.1) Power Cable:

The cord assembly mounted to the pump must not be modified in any way. This pump comes complete with a 3 wire cord and 3 prong grounded plug that must be connected into a 3 wire grounded Ground Fault receptacle. DO NOT remove ground pin from electrical plug. It is NOT recommended to use an extension cord with these pumps.

Do not use the power cable to lift pump.

C-4.2) Overload Protection:

Automatic thermal overload protects the sealed-in-oil motor, running dry may overheat the motor and trip the overload. The type of in-winding overload protector used is referred to as an inherent overheating protector and operates on the combined effect of temperature and current. This means that the overload protector will trip out and shut the pump off if the windings become too hot, or the load current passing through them becomes too high. It will then automatically reset and start the pump up after the motor cools to a safe temperature. In the event of an overload, the source of this condition should be determined and rectified immediately. Using a ohmmeter, check the resistance of the motor windings by connecting one lead clip to each electric "flat" prong on the power cord plug. The ohmmeter should be on R x 1 setting. Normal reading is 1.7/1.9 . To check for ground, place the ohmmeter on R x 100k, connect one lead clip to the "round" ground prong on the power cord and touch the other lead clip to each "flat" prong individually. If the reading is other than infinity, a leakage through stator insulation or moisture in the windings is occurring and the stator must be removed, dried out and rechecked. A reading at zero indicates a dead short and the stator will have to be replaced. DO NOT

LET THE PUMP CYCLE OR RUN IF AN OVERLOAD CONDITION OCCURS !

SECTION D: SERVICE AND REPAIR

NOTE: All item numbers ( ) refer to Figure 4.

D-1) Lubrication:

Anytime the pump is removed from operation, the cooling oil in the motor housing (5) must be checked visually for oil level and contamination.

D-1.1) Checking Oil:

To check oil, set unit upright. Remove gland nut on cable (10). With a flashlight, visually inspect the oil in the motor housing (5) to make sure it is clean, clear and that the oil level is above all internal componentry . If oil appears satisfactory, replace gland nut. If oil is low or appears contaminated, test oil as per section D-1.2
