GENERAL INFORMATION The Eemax Mini Tank water heaters can be used in most under the counter, point of use applications. EMT models are designed to supply hot water for all hand wash and kitchen sinks in a residential, commercial or industrial environment. EMT models can replace traditional central hot water heaters thereby conserving water and reducing energy waste. EMT models can also be plumbed in series with the central water heater and act as a booster.
TECHNICAL DESCRIPTION There are four Eemax Mini tank models, a 1.3 gallon, a 2.5 gallon, a 4 gallon and a 6 gallon model. The pressure vessel (water tank) is welded, glass lined steel and is equipped with an anode rod. The water heater is equipped with a thermostat and a high limit temperature switch. A temperature/pressure relief valve is supplied with the unit. INSTALLATION INSTRUCTIONS EMT1 - EMT2.5 - EMT4 - EMT6 The installation must be completed by a licensed professional.
PLUMBING CONNECTIONS Connect the cold water inlet pipe to the inlet nipple (marked with a blue ring) and the hot water outlet pipe to the outlet nipple (marked with a red ring). IMPORTANT: If Water pipes are copper or bronze, use dielectric connections to prevent corrosion. Failure to provide dielectric insulation may result in premature tank or nipple failure and may void your warranty. Insure that the water heater is installed in a level position.
T/P Valve Discharge pipe: 1. Must NOT be smaller in diameter than the outlet diameter of the valve, or have any reducing couplings. 2. Must NOT be plugged or blocked. 3. Must be made of suitable material for hot water. 4. Must not be over 15’ in length. 5. Must not have more than two elbows. 6. Must terminate at an adequate drain. 7. Must not have a shut off valve between relief valve and tank or relief valve and termination of discharge.
FILLING THE WATER HEATER CAUTION!: Before plugging the water heater electric cord into an outlet, be sure that the system is completely charged with water and ALL AIR IS REMOVED. Before connecting the power, fill the tank and system with water and check for leaks. To be sure that all air is out of the water system, open the hot water faucets on your fixtures until constant water flows from them. Otherwise any air remaining in the tank will cause the water heater element to self destruct.
ELECTRICAL CONNECTIONS To be certain that all of the air is out of the water heater, open the HOT water faucet on your fixtures until constant water flows from them. If air remains in the tank, the element will be damaged when the electric cord is plugged in. Connect the water heater to a GROUNDED OUTLET. The water heater is fitted with a power cord that is intended to plug into a grounded 110-120 V/AC receptacle. Adhere to all pertinent State and local codes.
INSTRUCTIONS FOR USE CONGRATULATIONS! You are now ready to use your water heater. Run the hot water at a nearby sink and evaluate the hot water temperature. Make any temperature adjustment using the section below: SETTING THE THERMOSTAT: The water heater is equipped with an adjustable thermostat that once set will automatically control water temperature. The red indicator lamp remains illuminated while the water is being heated.
MAINTENANCE INSTRUCTIONS Do not attempt to repair this water heater yourself. Call a service person (plumber or electrician) for service assistance. Always unplug the power supply cord when the water is turned off or when servicing or draining the water heater. Before calling for service, first confirm that the water heater is properly filled and that 110VAC power has not been interrupted.
DESCALING THE HEATING ELEMENT: Scale deposits can affect the heating capability of the element. Heavy scale can even cause the element to burn out. The element can be descaled chemically or manually. 1. Remove the heating element (see above). 2. To descale chemically, soak the heating element in white vinegar or other descaling solution and then rinse well with fresh water. 3.
RESETTING THE HIGH LIMIT SWITCH: For various reasons the high limit safety shut off switch will occasionally shut the water heater down. This shut down will occur when water temperatures exceed 190F. Power is automatically turned off to the heating element. The shut off device may activate as a result of a power outage or an electrical storm. NOTE: Do not attempt to reset the high limit switch without first allowing the water heater to cool down the high temperature water inside the heater.
TROUBLE SHOOTING PROBLEM: Water does not get hot 1. Make sure the power supply is on and working. 2. If light does not come on, check that the reset button is pushed in; follow steps from previous section. 3. If the indicator light is illuminated, but water temperature does not get hot at the sink, test for a plumbing crossover as follows; shut off cold water supply to water heater and open hot water tap. There should be no water flowing.
