INSTALLATION INSTRUCTIONS Removing the Old Water Heater The water passing out of the drain valve may be extremely hot. To avoid being scalded, make sure all connections are tight and that the water flow is directed away from any person. 4. Check again to make sure the electrical supply is turned “OFF” to the water heater. Then unplug the water heater (cord set) or disconnect the electrical supply connection from the water heater junction box. FIGURE 1. 1. Turn “OFF” electrical supply to the water heater.
from some plumbing wholesalers and retailers, and detect and react to leakage in various ways: • Sensors mounted in the drain pan that trigger an alarm or turn off the incoming water to the water heater when leakage is detected. • Sensors mounted in the drain pan that turn off the water supply to the entire home when water is detected in the drain pan. FIGURE 7.
HOTTER WATER CAN SCALD: Water heaters are intended to produce hot water. Water heated to a temperature which will satisfy clothes washing, dish washing, and other sanitizing needs can scald and permanently injure you upon contact. Some people are more likely to be permanently injured by hot water than others. These include the elderly, children, the infirm, or physically/ mentally handicapped.
NOTE: To protect against untimely corrosion of hot and cold water fittings, it is strongly recommended that dielectric unions or couplings be installed on this water heater when connected to copper pipe. 1. Look at the top cover of the water heater. The hot water outlet is marked hot. Put two or three turns of teflon tape around the threaded end of the threaded-to-sweat coupling and around both ends of the 3/4” threaded nipple.
is made with any live electrical part. The discharge opening must not be blocked or reduced in size under any circumstances. Excessive length, over 30 feet (9.14 m), or use of more than four elbows can cause restriction and reduce the discharge capacity of the valve. No valve or other obstruction is to be placed between the relief valve and the tank. Do not connect tubing directly to discharge drain unless a 6 inch air gap is provided.
Filling the Water Heater Never use this water heater unless it is completely full of water. To prevent damage to the tank and heating element, the tank must be filled with water. Water must flow from the hot water faucet before turning “ON” power. To fill the water heater with water: 1. Close the water heater drain valve by turning the handle to the right (clockwise). The drain valve is located on the lower front of the water heater. Before making the conversion to 5500 watts, check the (1) power supply .
Necessary element conversion parts are located in a small bag contained within the electrical junction box on top of the water heater. 4. Lower Element: Lift out the tab as shown to unclip the terminal cover from the thermostat. The terminal cover can now be removed from the thermostat. FIGURE 12. 1. Before beginning the conversion turn “OFF” electric power supply to the water heater. FIGURE 16. 5. Remove the screws from terminal 2 of the element, and move the looped end of the wire aside.
8. 11. Replace the access panel. Tighten terminals 2 and 3 to ensure proper electrical connection. FIGURE 21. 12. Complete wiring to the water heater, or if completed, turn “ON” electric power to the water heater after filling the tank with water. Failure to tighten terminal screws can cause a fire which can result in DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE. 9. Replace terminal cover on thermostat making sure that the locking tabs on the terminal cover are in place. FIGURE 22.
If you are not familiar with electric codes and practices, or if you have any doubt, even the slightest doubt, in your ability to connect the wiring to this water heater, obtain the service of a competent electrician. Contact your Sears salesperson to arrange for a professional electrician. For complete grounding details and all allowable exceptions, refer to the current edition of the NEC - National Electrical Code NFPA 70. 4.

SERVICE AND ADJUSTMENT Temperature Regulation The lower thermostat is factory set at a position which approximates 120°F (49°C), and is adjustable if a different water temperature is desired. Read all warnings in this manual and on the water heating before proceeding. HOTTER WATER CAN SCALD: Water heaters are intended to produce hot water. Water heated to a temperature which will satisfy clothes washing, dish washing, and other sanitizing needs can scald and permanently injure you upon contact.
Temperature-Pressure Relief Valve Operation NOTE: It is not necessary to adjust the upper thermostat. However, if it is adjusted above the factory set point of 120°F (49°C), it is recommended that it not be set higher than the lower thermostat setting. The temperature-pressure relief valve must be manually operated at least once a year. The upper and lower thermostats are adjustable if a different water temperature is desired. Read all warnings in the “Temperature-Regulation” section before proceeding.
The water heater should be drained if being shut down during freezing temperatures. Also, periodic draining and cleaning of sediment from the tank may be necessary. 1. Turn “OFF” the electrical power to the water heater at the junction box. 2. Remove the access panel and the insulation cap with handle. 3.
