Accessories and Tools Needed Accessories To simplify the installation Maytag has available the installation parts shown below. You may or may not need all of these accessories depending on your type of installation. Call a Maytag Service Specialist at 1-800-365-0024 for an authorized installer.
Instructions for Installation Removing the Old Water Heater 1 Turn “OFF” electrical supply to the water heater. 5 a. If you have copper piping to the water heater, the two copper water pipes can be cut with a hacksaw approximately four inches away from where they connect to the water heater. This will avoid cutting off the pipes too short. Additional cuts can be made later if necessary. Disconnect the temperature-pressure relief valve drain line.
Instructions for Installation (cont’d) Locating The New Water Heater CAUTION WATER HEATERS EVENTUALLY LEAK: Installation of the water heater must be accomplished in such a manner that if the tank or any connections should leak, the flow of water will not cause damage to the structure. For this reason, it is not advisable to install the water heater in an attic or upper floor. When such locations cannot be avoided, a suitable drain pan should be installed under the water heater.
Instructions for Installation (cont’d) Water Piping * NOTE: Your water heater is super insulated to minimize heat loss from the tank. Further reduction in heat loss can be accomplished by insulating the hot water lines from the water heater. WARNING 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.
Instructions for Installation (cont’d) Temperature-Pressure Relief Valve WARNING WARNING At the time of manufacture this water heater was provided with a combination temperature-pressures relief valve certified by a nationally recognized testing laboratory that maintains periodic inspection of production of listed equipment or materials, as meeting the requirements for Relief Valves and Automatic Gas Shutoff Devices for Hot Water Supply Systems, and the current edition of ANSI Z21.22 • CSA 4.
Instructions for Installation (cont’d) Filling the Water Heater 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 on the lower front of the water heater. 2. Open the cold water supply valve to the water heater. NOTE: The cold water supply valve must be left open when the water heater is in use. 3. To insure complete filling of the tank, allow air to exit by opening the nearest hot water faucet.
Instructions for Installation (cont’d) Wiring C. Flexible metal conduit or 3 metallic tubing shall be permitted for grounding if all the following conditions are met: 1. The length in any ground return path does not exceed 6 feet. 2. The circuit conductors contained therein are protected by overcurrent devices rated at 20 amperes or less. 3. The conduit or tubing is terminated in fittings approved for grounding.
Instructions for Installation (cont’d) Installation Checklist COLD HOT 1. Whether or not the element conversion is made, the model rating plate must be marked. Using a hard point ink pen, check the appropriate block within the model rating plate, which is located adjacent to the lower access panel. 2. Is the fuse or circuit breaker size correct as shown in the chart in the “Product Specifications” section? HOT COLD CONDUIT 3.
Service and Maintenance Temperature Regulation LOWER THERMOSTAT WITH HIGH LIMIT WARNING 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.
Service and Maintenance (cont’d) Thermostat Adjustments replaced more often than an anode rod that appears to be intact. Replacement of a depleted anode rod can extend the life of your water heater. Inspection should be conducted by a qualified service technician, and at a minimum should be checked annually after the warranty period. The upper and lower thermostats have been factory set at HOT (approximately 120°F) to reduce the risk of scald injury.
Service and Maintenance (cont’d) Draining Thermostat Removal/Replacement 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. 1. Before beginning turn “OFF” the electric power supply to the water heater.
Service and Maintenance (cont’d) Thermostat Removal (cont’d) 9. Put plastic terminal cover back in place. 3. Attach a hose to the water heater drain valve and put the other end in a floor drain or outdoors. Open the water heater drain valve. Open a nearby hot water faucet which will relieve pressure in the water heater and speed draining. 10. Replace the insulation block and pad to cover the thermostat. 11. Replace access panel, then turn the electric power “ON”.
Service and Maintenance (cont’d) 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. Lift out tab to unclip terminal cover from thermostat. 11. Close the water heater drain valve by turning the handle to the right (clockwise). The drain valve is on the lower front of the water heater. 12. Open the cold water supply valve to the water heater.
Service and Maintenance (cont’d) Element Cleaning/ Replacement (cont’d) Drain Valve Washer Replacement 16. Replace the terminal cover on the thermostat making sure that the locking tabs on the terminal cover are in place. NOTE: For replacement, use a 17⁄32″ x 13⁄64″ x 1⁄8″ thick washer available at your nearest hardware store. For ordering a replacement washer, refer to the “Repair Parts” section. 1. Before beginning turn “OFF” the electrical power supply to the water heater.
Troubleshooting Start Up Conditions THERMAL EXPANSION Smelly water may be eliminated or reduced in some water heater models by replacing the anode(s) with one of less active material, and then chlorinating the water heater tank and all hot water lines. Call a Maytag Service Specialist at 1-800-365-0024 for an authorized servicer for further information concerning an Anode Replacement Kit #9001453 and this Chlorination Treatment.
Troubleshooting (cont’d) NOT ENOUGH OR NO HOT WATER 1. Before beginning, turn “OFF” electrical power supply to the water heater. 1. In a new installation, the water heater may not be properly connected. Make sure the cold water supply valve is open. Review and check piping installation. Make sure that the cold water line is connected to the cold water inlet to the water heater and the hot water line to the hot water outlet on the water heater. 2.
Troubleshooting (cont’d) Leakage Checkpoints Use this guide to check a “Leaking” water heater. Many suspected “Leakers” are not leaking tanks. Often the source of the water can be found and corrected. CAUTION Read this manual first, then before checking the water heater make sure the electric supply has been turned “OFF”, and never turn the electric supply “ON” before the tank is completely full of water.
