Flexible metal conduit or flexible metallic tubing shall be permitted for grounding if all the following conditions are met:

1.The length in any ground return path does not exceed 6 feet.

2.The circuit conductors contained therein are protected by overcurrent devices rated at 20 amperes or less.

3.The conduit or tubing is terminated in fittings approved for grounding.

Never use this solar water heater unless it is completely full of water.

SOLAR WATER HEATERS EQUIPPED FOR ONE TYPE VOLTAGE ONLY. This solar water heater is equipped for one type of voltage only. Check the rating plate near the bottom access panel for the correct voltage. DO NOT USE THIS SOLAR WATER HEATER WITH ANY VOLTAGE OTHER THAN THE ONE SHOWN ON THE MODEL RATING PLATE. Failure to use the correct voltage can cause problems which can result in DEATH, SERIOUS BODILY INJURY OR PROPERTY DAMAGE. If you have any questions or doubts consult your electric company.

If wiring from the fuse box or circuit breaker box was alumi- num for the old tank, replace it with copper wire. If you wish to reuse the existing aluminum wire, have the connection at the solar water heater made by a competent electrician. Contact your local utility to arrange for a professional elec- trician.

THERMOSTAT

Each thermostat is factory preset at 120°F to reduce the risk of scald injury. This setting has proven by experience to be most satisfactory from the standpoint of operational costs and household needs.

Solar water heaters installed in Florida require the thermostat(s) to be set at 125°F. If you wish to adjust the settings, see the “Temperature Adjustment” section of this installation manual on page 11.

TEMPERATURE REGULATION

HOTTER WATER CAN SCALD: Solar water heaters are

intended to produce hot water. Water heated to a temperature which will satisfy clothes washing, dish washing, and other sanitizing needs can cause scalds resulting in serious personal injury and/or death. Some people are more likely to be permanently injured by hot water than others. These include the elderly, children, the infirmed, or physically handicapped. 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. Please see Figure 7 and Table 2 for information regarding thermostat settings. In addition to using the lowest possible temperature setting that satisfies your hot water needs, some type of mixing device, such as a mixing valve should be used at the hot water taps used by these people or at the solar water heater. Mixing valves are available at plumbing supply or hardware stores. Follow manufacturers instructions for installation of the valves. Before changing the factory setting of the thermostat, read the Temperature Adjustment section. KEEPING THE THERMOSTAT SETTING AT 120°F WILL REDUCE THE RISK OF SCALDS. Never allow small children to use a hot water tap, or to draw their own bath water. Never leave a child or handicapped person unattended in a bathtub or shower.

TEMPERATURE SETTINGS

NOTE: This residential solar water heater will not supply sanitizing hot water for dishwashers.

The thermostat is factory set at its lowest position which approximates 120°F and is adjustable if a different water temperature is desired. For best system savings this temperature should not be changed. Read all warnings in this manual and on the solar water heater before proceeding.
