HOTTER WATER CAN SCALD:
Water heaters are intended to produce hot water. Water heated to a temperature which will satisfy space heating, clothes washing, dish washing,andothersanitizingneedscan scald and permanentlyinjure 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 disabled. If anyone using hot water in your home fits into one of these groups or if there is a local code or state law requiring a certain temperature water at the hot water tap, then you must take special precautions. In addition to using the lowest possible temperature setting that satisfies your hot water needs, a means such as a mixing valve should be used at the hot water taps used by these people or at the water heater. Mixing valves are available from your local plumbing contractor. Consult a Qualified Installer or Service Agency. Follow mixing valve manufacturer’s instructions for installation of the valves. Before changing the factory setting on the thermostat, read the “Temperature Regulation” section
in this manual.

LOCATING THE NEW SOLAR WATER HEATER
FACTS TO CONSIDER ABOUT THE LOCATION
Carefully choose an indoor location for the new solar water heater, because the placement is a very important consideration
for the safety of the occupants in the building and for the most economical use of the water heater.
Whether replacing an old water heater or putting the water heater in a new location, the following critical points must be observed:
1.Select a location indoors as close as practical or centralized to the water piping system as possible. The solar water heater should be located in an area not subject to freezing temperatures.
2.Selected location must provide adequate clearances (4”/101.6 mm) for servicing parts such as the thermostats, drain valve, and relief valve. Adequate clearance for servicing this water heater should be considered before installation, such as changing the anodes, etc.
3.The solar water heater should be located so it is not subject to physical damage by moving vehicles or area flooding.
Installation of the solar water heater must be accomplished in such a manner that if the tank or any connections should leak, the flow will not cause damage to the structure. For this reason, it is not advisable to install the solar water heater in an attic or upper floor. When such locations cannot be avoided, a suitable metal drain pan should be installed under the solar water heater. Drain pans are available from your local plumbing contractor.
Such a drain pan must have a minimum length and width of at least 2 inches (51 mm) greater that the water heater dimensions and must be piped to an adequate drain.
Water heater life depends upon water quality, water pressure and the environment in which the water heater is installed. Water heaters are sometimes installed in locations where leakage may result in property damage, even with the use of a drain pan piped to a drain. However, unanticipated damage can be reduced or prevented by a leak detector or water shut-off device used in conjunction with a piped drain pan. These devices are available from some plumbing supply wholesalers and retailers, and detect and react to leakage in various ways:
•Sensors mounted in the drain pan that trigger an alarm or turn off the incoming water to the water heater when leakage is detected.
•Sensors mounted in the drain pan that turn off the water supply to the entire home when water is detected in the drain pan.
•Water supply shut-off devices that activate based on the water pressure differential between the cold water and hot water pipes connected to the water heater.
INSULATION BLANKETS
Insulation blankets are available to the general public for external use on electric water heaters but are not necessary with this product. The purpose of an insulation blanket is to reduce the standby heat loss encountered with storage tank heaters. Your water heater meets or exceeds the National Appliance Energy ConservationAct standards with respect to insulation and standby loss requirements, making an insulation blanket unnecessary.
Should you choose to apply an insulation blanket to this heater, you should follow these instructions below. Failure to follow these instructions can result in fire, serious personal injury, or death.
•Do not cover the temperature and pressure relief (T & P) valve with an insulation blanket.
•Do not cover the instruction manual. Keep it on the side of the water heater or nearby for future reference.
•Do obtain new warning and instruction labels for placement on the blanket directly over the existing labels.

LOCAL CODES
The installation of solar water heater must be in accordance with these instructions and all applicable local codes and electric utility requirements. In the absence of local codes, install in accordance with the current edition of the National Electrical Code (NFPA-70).
