The grounding prong in the plug is connected through the green wire inside the cord to the grounding system in the tool. The green wire in the cord must be the only wire connected to the tool’s grounding system and must never be attached to an electrically

“live” terminal. (See 3-Prong Plug and Outlet.)

The tool must be plugged into an appropriate outlet, properly installed and grounded in accordance with all codes and ordinances. The plug and outlet should look like those in the preceding illustration. (See 3-Prong

Plug and Outlet.)

Double insulated tools may be used in either of the 120 volt outlets shown in the preceding illustration. (See

Outlets for 2-Prong Plug.)

Extension Cords

Grounded tools require a three wire extension cord. Double Insulated tools can use either a two or three wire extension cord.

As the distance from the supply outlet increases, you must use a heavier gauge extension cord. Using extension cords with inadequately sized wire causes a serious drop in voltage, resulting in loss of power and possible tool damage.

(See Table A.)

The smaller the gauge number of the wire, the greater the capacity of the cord. For example, a 14 gauge cord can carry a higher current than a 16 gauge cord. (See Table A.)

When using more than one extension cord to make up the total length, make sure each cord contains at least the minimum wire size required.

(See Table A.)

If you are using one extension cord for more than one tool, add the nameplate amperes and use the sum to determine the required minimum cord size. (See Table A.)

If you are using an extension cord outdoors, make sure it is marked with the suffix “W-A” (“W” in Canada) to indicate it is acceptable for outdoor use.

Make sure the extension cord is properly wired and in good electrical condition. Always replace a damaged extension cord or have it repaired by a qualified electrician before using it.

8. Protect the extension cords from sharp objects, excessive heat, and damp or wet areas.

Pipe is secured to a solid surface, with appropriate hardware (not included), to ensure the stability of the Pump. (See Figure E.)

4. Install an additional union (not included) or other means of separating the Discharge Pipe just above the floor to facilitate removal of the Pump if necessary.

(See Figure E.)

5. A check valve (not included) is recommended just above, or in place of, the union to prevent the backflow of water after each pump cycle. If a Check Valve is used, a 1/8” diameter air bleed hole should be drilled through the Discharge Pipe just above the lower Base (25) to prevent Pump “airlock”. A small spray of water out of

this hole is normal while the Pump is running. (See Figure E.)
