convenience box. It may contain a disconnect switch

and/or receptacle if water heater is cord connected.

flexible (metallic or plastic) cable containing 2, 3, or 4

insulated wires of different colors.

eye level (also out of reach of small children), and such

that existing cable (Fig. 2 or Fig. 3, Item l) may be utilized.

• Measure the distance n from the Time Switch to Water
