Operation SAFETY PRECAUTIONS A. Do turn off power to water heater if it has been subjected to over heating, fire, flood or physical damage. B. Do Not turn on water heater unless it is filled with water. C. Do Not turn on water heater if cold water supply shut-off valve is closed. D. If there is any difficulty in understanding or following the OPERATION or MAINTENANCE instructions, it is recommended that a qualified person or serviceman perform the work. ! CAUTION Hydrogen gas can be produced in a hot water system served by this water heater that has not been used for a long period of time (generally two weeks or more). HYDROGEN GAS IS EXTREMELY FLAMMABLE!! To dissipate such gas and to reduce risk of injury, it is recommended that the hot water faucet be opened for several minutes at the kitchen sink before using any electrical appliance connected to the hot water system. If hydrogen is present, there will probably be an unusual sound such as air escaping through the pipe as the water begins to flow. Do not smoke or use an open flame near the faucet at the time it is open. 1. WATER TEMPERATURE SETTING - The temperature of the water in the water heater can be regulated by setting the temperature dial of the adjustable surface mounted thermostat located behind the jacket access panel. This thermostat controls the water heater's heating element only. (A seperate thermostat should be utilize in monitoring the temperature from the collector)To comply with safety regulations the thermostat are factory set at 120° F or less where local codes require. Reset Button ESE TR ESE TR Thermostat Dial Pointer Thermostat Protective Cover 150°F 90°F 125°F TURN OFF POWER BEFORE SERVICING CAUTION!! - Hotter water increases the risk of SCALDING! This illustration shows the temperature adjustment dial used for setting the water temperature. Refer to Section 1 - Water Temperature Setting, above, for more details and safety instructions regarding water temperature setting. Figure 4. - Thermostat and Protective Cover. Safety and energy conservation are factors to be considered when selecting the water temperature setting of the water heater's thermostat . The lower the temperature setting the greater the savings in energy and operating costs. ! DANGER There is a Hot Water SCALD Potential if the thermostat is set too high. NOTE: Households with small children or invalids may require a 120° F or lower thermostat setting to prevent contact with "HOT" water. 7 TIME / TEMPERATURE RELATIONSHIPS IN SCALDS Temperature 120° F 125° F 130° F 135° F 140° F 145° F 150° F 155° F Time to Produce Serious Burn More than 5 minutes 11/2 to 2 minutes About 30 seconds About 10 seconds Less than 5 seconds Less than 3 seconds About 11/2 seconds About 1 second Table courtesy of Shriners Burn Institute ! DANGER Make certain power to water heater is OFF before removing jacket access pane FOR ANY REASON. If adjustment is necessary, turn off power to water heater, remove jacket access panel and insulation exposing thermostat. The thermostat protective cover should not be removed. Set thermostat dial pointer, with a small screwdriver, to desired temperature. (Refer to Fig. 4.) Replace insulation and jacket access panel. Turn on power to water heater. 2. SAFETY CONTROLS - The water heater is equipped with a combination Thermostat and Temperature Limiting Control (ECO) that is located above the heating element in contact with the tank surface. If for any reason the water temperature becomes excessively high, the Temperature Limiting Control (ECO) breaks the power circuit to the heating element. Once the control opens, it must be reset manually. ! CAUTION The cause of the High Temperature Condition must be investigated by qualified service personnel and corrective action taken before placing the water heater in service again. To reset Temperature Limiting Control, turn off power to water heater, remove jacket access panel and insulation. The ther-
