INST ALLA TION INSTRUCTIONS INSTALLA ALLATION 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.
• 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. INSULATION BLANKETS Insulation blankets are available to the general public for external use on electric water heaters but are not necessary with this product.
supply or hardware stores. Follow manufacturers instructions for installation of the valves. Before changing the factory setting on the thermostat, read the “Temperature Regulation” section in this manual. INSTALLATION IN RESIDENTIAL GARAGES: The water heater must be located and/or protected so it is not subject to physical damage by a moving vehicle. • The location selection must provide adequate clearances for servicing and proper operation of the water heater.
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. Water Piping 1. Look at the upper pipe nipple on the water heater. The water outlet is marked hot. Connect the hot water pipe to the hot water outlet of the water heater. 2. Look at the lower pipe nipple on the water heater. The cold water inlet is marked cold.
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. To prevent bodily injury, hazard to life, or property damage, the relief valve must be allowed to discharge water in quantities should circumstances demand.
Converting the Lower Element 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. Refer to “The Convertible Lower Element” section. The Upper Element is a conventional 3800 watt element which only operates at its rated wattage on 240 volts. (See rating plate on the water heater.
Necessary element conversion parts are located in a small bag contained within the large plastic manual envelope attached to the side 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.
8. Tighten terminals 2 and 3 to ensure proper electrical connection. 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. Failure to tighten terminal screws can cause a fire which can result in DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE. 9.
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. Call Maytag Customer Service at 1-800-788-8899 for an authorized servicer. • The length in any ground return path does not exceed 6 feet. • The circuit conductors contained therein are protected by overcurrent devices rated at 20 amperes or less.

SERVICE AND MAINTENANCE Temperature Regulation LOWER THERMOSTAT WITH HIGH LIMIT LOWER THERMOSTAT WITHOUT HIGH LIMIT FIGURE 28. 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.
The upper and lower thermostats are adjustable if a different water temperature is desired. Read all warnings in the “Temperature Regulation” section before proceeding. 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) HOT it is recommended that it not be set higher than the lower thermostat setting.
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.
NOTE: These instructions are written for element cleaning and element replacement for the lower element. If it is necessary to clean or replace the upper element, then repeat these instructions. To remove the element from your tank in order to clean or replace it: 1. Before beginning turn “OFF” the electric power supply to the water heater. FIGURE 34. 5. Remove the insulation cap with handle to expose the terminal cover. FIGURE 31. 2.
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.
• Before beginning turn “OFF” the electrical power supply to the water heater. 18. Replace access panel. 19. Turn “ON” electric power to water heater. • Follow “Draining” instructions in the “Service and Maintenance” section. • 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.
Operational Conditions RUMBLING NOISE SMELLY WATER In some water areas, scale or mineral deposits will build up on your heating elements. This buildup will cause a rumbling noise. Follow “Element Cleaning/Replacement” instructions to clean and replace the elements. In each glass-lined water heater there is installed one anode rod (see parts section) for corrosion protection of the tank. Certain water conditions will cause a reaction between this rod and the water.
5. Replace the insulation cap with handle so that it completely covers the thermostat and element. 5. Check to see the electric service to your house has not been interrupted. If this is the case, contact the electric company. 6. Is the thermostat set to the desired temperature? See “Temperature Regulation” section. 7. If you had experienced very hot water and now no hot water, the problem may be due to the high temperature shut off system.
F Water from drain valve may be due to the valve being opened slightly G *The drain valve may be leaking at the tank fitting. H Water in the water heater bottom or on the floor may be from condensation, loose connections or the temperaturepressure relief valve. DO NOT replace the water heater until a full inspection of all possible water sources is made and necessary corrective steps taken. Leakage from other appliances, water lines, or ground seepage should also be checked.
