MATERIALS AND BASIC TOOLS NEEDED Materials Needed To simplify the installation Sears has available the installation parts shown below. You may or may not need all of these materials, depending on your type of installation. EXPANSION TANKS FOR THERMAL EXPANSION CONDITIONS AVAILABLE IN 2 GALLONS , AND 5 GALLONS CAPACITY THROUGH LOCAL SEARS STORE OR SERVICE CENTER. WATER HEATER INSTALLATION KIT WITH FLEXIBLE CONNECTORS FOR 3/4” OR 1/2” THREADED OR COPPER PLUMBING.
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 4. 5a.
• Sensors mounted in the drain pan that turn off the water supply to the entire home when water is detected in the drain pan. • Water supply shut-off devices that activate based on the water pressure differential between the cold water and hot water pipes connected to the water heater. Mineral buildup or sediment may have accumulated in the old water heater. This causes the water heater to be much heavier than normal and this residue, if spilled out, could cause staining.
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.
Fit T & P valve insulation over valve. Make sure that the insulation does not interfere with the lever of the T & P valve. NOTE: To protect against untimely corrosion of hot and cold water fittings, it is strongly recommended that di-electric unions or couplings be installed on this water heater when connected to copper pipe. Secure all insulation using tape. 1. Look at the top cover of the water heater. The hot water outlet is marked hot.
If after manually operating the valve, it fails to completely reset and continues to release water, immediately close the cold water inlet to the water heater, follow the draining instructions, and replace the temperature-pressure relief valve with a new one. Position the valve downward and provide tubing so that any discharge will exit only within 6 inches (153 mm) above, or at any distance below the structural floor. Be certain that no contact is made with any live electrical part.
Converting the Lower Element Necessary element conversion parts are located in a small bag contained within the electrical junction box on top of the water heater. These instructions only cover the conversion of the convertible element, read this entire manual before attempting to install or operate the water heater. The water heater is factory set to operate at 3800 watts. The lower element can be converted to operate at 5500 watts.
8. Failure to tighten terminal screws can cause a fire which can result in DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE. FIGURE 16. 5. Tighten terminals 2 and 3 to ensure proper electrical connection. Remove the screws from terminal 2 of the element, and move the looped end of the wire aside. 9. Replace terminal cover on thermostat making sure that the locking tabs on the terminal cover are in place. FIGURE 17. 6. The buss bar is labeled 5500 W.
11. Replace the access panel. 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. If wiring from your fuse box or circuit breaker box was aluminum for your old water heater, replace it with copper wire. If you wish to reuse the existing aluminum wire, have the connection at the water heater made by a competent electrician. Contact your Sears salesperson to arrange for a professional electrician. 1.
5. Wiring Diagrams (see “Wiring Diagrams” section) have been supplied showing the two most common types of connections between the water heater and the power supply. You can easily see which type connection you have by removing the junction box cover on top of the water heater. • • 6. Use wire nuts and connect the power supply wiring to the wires inside the water heater’s junction box. 7. The water heater must be electrically “grounded” by the installer.

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. Lift out the tab as shown below to unclip the terminal cover from the thermostat. The terminal cover can now be removed from the thermostat. 1.
4. Remove the two screws securing the access panel, and remove panel. FIGURE 33. 1. Before beginning turn “OFF” the electric power supply to the water heater. 5. Remove the insulation cap with handle. FIGURE 30. 2. Turn off the water supply to the water heater at the water Shut-off valve or water meter. FIGURE 34. 6. 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 31. 3.
8. Clean the area around the element opening. Remove any sediment from or around the element opening, inside the tank. 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. 9. If you are cleaning the element you have removed, do so by scraping or soaking in vinegar or a de-liming solution. 14. Check element for water leaks.
18. Replace access panel. • Follow “Draining” instructions. See “Draining” section. 19. Turn “ON” electric power to water heater. • Turning counter clockwise, remove the hex cap below the screw handle. • Remove the washer and put the new one in place. • Screw the handle and cap assembly back into the drain valve and retighten using a wrench. DO NOT OVER TIGHTEN. • Follow “Filling the Water Heater” instructions in the “Installation Instructions” section. FIGURE 41. • Check for leaks.
TROUBLESHOOTING Start Up Conditions NOTE: Expansion tanks are pre-charged with a 40 psi air charge. If the inlet water pressure is higher than 40 psi, the expansion tank’s air pressure must be adjusted to match that pressure, but must not be higher than 80 psi.
D. An excess of active hydrogen in the tank. This is caused by corrosion protective action of the anode. Smelly water may be eliminated or reduced in some water heater models by replacing the anode rod (s) with one of less active material, and then chlorinating the water heater tank and all hot water lines. Contact the local Sears Service Center for further information concerning an Anode Replacement Kit #9001453 and this Chlorination Treatment.
2. Make sure the electrical supply to your water heater is “ON”. 3. Check for loose or blown fuses in your water heater circuit. Circuit breakers weaken with age and may not handle their rated load and should be replaced. 4. Make certain the disconnect switch, if used, is in the “ON” position. 5. Check to see the electric service to your house has not been interrupted. If this is the case, contact the electric company. 6. 7. shut off system.
LEAKAGE CHECKPOINTS 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. The water must flow from the hot water faucet before turning “ON” power. A. *Condensation may be seen on pipes in humid weather or pipe connections may be leaking. B. Small amounts of water from the temperature-pressure relief valve may be due to thermal expansion or high water pressure in your area. C.
