• TOP VIEW 3” Water pH between 6.5 and 8.5 • pH levels below 6.5 can cause an increase in the rate of corrosion. pH of 8.5 or higher can potentially cause lime scale build-up • Maintain water pH between 6.5 and 8.5. Check with litmus paper or have it chemically analyzed by a local water treatment company. • If the pH is not between 6.5 and 8.5, consult a local water treatment company for solutions.

Part 3 - Piping A. Plumbing It is mandatory that all plumbing be done in accordance with federal, local, and state plumbing codes and practices. Failure to properly install the water heater WILL VOID the warranty. It is also necessary to use both thread tape and pipe sealing compound on all mechanical plumbing connections. It is recommended to use unions on the hot and cold water connections to easily disconnect the water heater for servicing. Dielectric fittings must be used on water connections.
F. Temperature and Pressure Relief Valve For protection against excessive pressures and temperatures in this water heater, install temperature and pressure protective equipment as required by local codes, but not less than a combination T&P valve meeting the requirements for Relief Valves and Automatic Gas Shutoff Devices for Hot Water Supply Systems, ANSI Z21.22B / CSA 4.4-M99 by a nationally recognized testing laboratory that maintains periodic inspection of production listed equipment and materials.
Table 1 details the relationship of water temperature and time with regard to scald injury and may be used as a guide in determining the safest water temperature for your applications. H. Filling the Heater • Make certain that the drain valve is completely closed. • Open the shut-off valve in the cold water supply line. • Open the hot water faucets to allow air to vent from the heater and piping. • Allow sufficient time for the heater to completely fill with water.
Part 4 - Wiring Install wiring and electrically ground appliance in accordance with the authority having jurisdiction or, in the absence of such an authority, follow the National Electrical Code, NFPA 70, and/ or CSA C22.1 Electrical Code-Part 1 in Canada. Failure to follow all applicable local, state, and national regulations, mandates, and building supply codes for guidelines to install the electrical power supply could result in property damage, serious personal injury, or death.

Part 6 - Operation Tank must be full of water before the power is turned on. The heating element will be damaged if energized for even a short time while tank is dry. Failures due to “dry-firing” ARE NOT covered by warranty. After water and electrical connections have been made and tank is filled with water, turn on power to the heater. The heater is now in operation. A.
Completely drain the water heater before removing and replacing a heating element. Failure to do so will result in a leakage of water and property damage, and could possibly result in moderate to severe personal injury or death. Part 7 - Maintenance Considerations • To avoid electric shock, disconnect electrical supply before performing maintenance. • To avoid severe burns, allow heater to cool before performing maintenance. Water drained from the water heater may be scalding hot.
Leakage Checkpoints Water drained from the water heater may be scalding hot. Take care to avoid scalding. Wear gloves and safety glasses, and direct water to a safe drainage location. It is recommended to turn power off to the water heater and run water at a hot water faucet until it cools BEFORE draining water from the heater. Failure to comply with this warning could result in property damage, severe personal injury, or death.
