! General Safety Precautions Be sure to read and understand the entire Use & Care Manual before attempting to install or operate this water heater. It may save you time and cost. Pay particular attention to the General Safety Precautions. Failure to follow these warnings could result in serious bodily injury or death .
Introduction Thank you for buying your non-metallic electric water heater. Your new water heater is made of the latest materials and will not rust or corrode. It will give many years of hot water service when installed, operated and maintained according to the instructions in this manual. Your water heater is completely assembled and ready to install. This manual provides the general instructions for installation.

Installation 3. WATER SUPPLY CONNECTIONS — Refer to Fig. 2 for suggested typical installation. The installation of unions or flexible copper connectors is recommended on the hot and cold water connections so that the water heater may be easily disconnected for servicing if necessary. The HOT and COLD water connections are clearly marked and are 3/4” NPT on all models. Install a shut-off valve in the cold water line near the water heater. 4.
Installation To prevent stress on the relief valve fitting, which may damage the tank, support the drain pipe using metal strapping or similar method to an overhead point. Refer to Figure 3 for typical strapping method. NOTE: Local codes shall govern the installation of relief valves. Metallic Conduit or Metal Sheathed Cable and fittings approved for use as a grounding conductor.
Installation power supply provided is equivalent to that marked on the water heater’s rating plate. All wiring must conform to local codes or, in the absence of local codes, the latest edition of National Electrical Code ANSI/NFPA 70. The complete wiring schematic diagram for standard nonsimultaneous operation units is shown below in Figure 6.
Installation 8. PIPE WRAP ENERGY KIT — A pipe wrap energy saving kit consisting of two lengths of foam insulation is included with this water heater. To realize maximum energy savings, all exposed pipes should be insulated. However, most of the energy losses occur close to the water heater. This kit is designed to minimize this loss. Install one piece of insulation on the cold water supply line and the other piece on the hot water line. (Refer to Figure 9).
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 completely 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.

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 Reset Button Temperature Adjustment Screw (Shown at Factory Setting of approx. 120° F.) Table courtesy of Shriners Burn Institute HI setting equals approximately 170° F water temperature.
Operation ! CAUTION B. Remove the four (4) screws securing the thermostat access panel and the two (2) thermostat insulation pads, exposing the thermostat. The plastic personnel protector should not be removed. 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. C. With a small screwdriver, adjust the thermostat setting. This thermostat is marked in degrees from 110°F to 170°F.
Maintenance Properly maintained, your new, non-metallic water heater will provide years of dependable trouble-free service. It is suggested that a routine preventive maintenance program be established and followed by the user. It is further recommended that a periodic inspection of the operating controls, heating element and wiring should be made by service personnel qualified in electric appliance repair. appliances can cause a pounding “water hammer” sound.
Maintenance G. To expose the element for removal, lift up the hinged portion of the thermostat protective cover by gently pulling the lower corners up and away from the thermostat. Be careful to avoid pulling the thermostat from its mounting bracket, or bending the thermostat bracket. 3. HEATING ELEMENTS — Most water supplies will cause scale or mineral deposits to form on the heating elements. As the scale forms, it gets increasingly harder for the element to heat water.
Maintenance 4. VACATION AND LONG TIME SHUTDOWN — ! DANGER If the water heater is installed where it could freeze (summer cabin, lake home, etc.) you must drain all water from it and the piping. If the tank is full of water and it freezes, the tank will break. Freeze damage is not covered by the warranty! The water drained from the tank may be hot enough to present a SCALD HAZARD and should be directed to a suitable drain to prevent injury or damage.
Trouble Shooting Guide (cont’d) NATURE OF TROUBLE POSSIBLE CAUSE SERVICE Water too hot or not hot enough (cont’d) 3. Thermostat access panel(s) and/or insulation not in place 4. Thermostat(s) not resting tightly against mounting plate Noisy heating element(s) 1. Scale build-up on elements Water Leaks 1.
