OPERATING YOUR WATER HEATER
Before Using
1. Make sure the solar storage tank water heater has
been properly installed. See “Installing Your Water
Heater” section.
2. Completely fill the tank with water. (See Figure 2)
3. After the solar storage tank water heater tank is
completely filled with water, connect electrical power to
the solar storage tank water heater.
4. Read the “Water Temperature Regulation” section of
this manual. If the instructions are not clear, contact a
quali
fi
ed person.
5. Adjust the thermostat to the desired temperature
setting as described under “Adjusting the Thermostat/
High Limit Control” section.
IMPORTANT: Do not attempt to operate this solar storage
tank water heater if the thermostat(s), or surrounding
insulation has been exposed to water in any way.
Immediately call a quali
fi
ed person to inspect the solar
storage tank water heater and replace any thermostat or
insulation that has been exposed to water.
Do not attempt to repair these parts. Solar storage tank
water heaters subjected to
fl
ood conditions or any time
the thermostat(s) have been submerged in water require
replacement of the entire solar storage tank water heater.
Safety Shut-off
This solar storage tank water heater is designed
to automatically shut-off in the event that the water
temperature exceeds 170°F or 77°C (190°F or 88°C in
LDCE Models). A high limit control switch is used to shut off
the power to the elements if the water temperature exceeds
170°F or 77°C (190°F or 88°C in LDCE Models). The high
limit control can be reset by
fi
rmly pushing in the red reset
button located on the thermostat. Follow the instructions
under “Adjusting the Thermostat/High Limit Control”,
section to properly reset the high limit control. If the high
limit control switch continues to shut-off the water heater
contact a quali
fi
ed person for service.
Water Temperature Regulation
Water temperature over 125°F can cause
severe burns instantly or death from scalds.
Children, disabled and elderly are at highest
risk of being scalded.
Feel water before bathing or showering.
Temperature limiting valves are available.
WARNING
The thermostat is adjusted to a temperature setting
of 120°F or lower when it is shipped from the factory.
Water temperature can be regulated by adjusting
the thermostat to the preferred setting as shown in
“Adjusting the Thermostat /High Limit Control.”
The
preferred starting point is 120°F. There is a hot water
scald potential if the thermostat is set too high.
IMPORTANT:
Adjusting the thermostat past 120°F on
the thermostat will increase the risk of scald injury in the
times shown below.

NOTE: During low demand periods when hot water is not
being used, a lower thermostat setting will reduce energy
losses and may satisfy your normal hot water needs.
If hot water use is expected to be more than normal, a
higher thermostat setting may be required to meet the
increased demand.
When leaving your home for extended periods
(vacations, etc.) turn the thermostat to its lowest setting.
This will maintain the water at low temperatures with
minimum energy losses and prevent the tank from
freezing during cold weather.
