EQUIREMENTS
A properly licensed contractor must make the 230-volt electrical connection to the water heater
or solar storage tank and the electronic time switch (Optional). If your solar contractor is not
allowed by law to make these connections consult a licensed electrician.
N
EVER ACTIVATE THE CIRCUIT BREAKER CONTROLLING THE ELECTRICAL HEATING ELEMENT
UNTIL THE SOLAR STORAGE TANK IS COMPLETELY FILLED WITH WATER
.
This will prevent
“dry firing” of the heating element. The electrical heating element will be destroyed almost
instantaneously if not completely submerged in water when activated. Make sure the water
heater circuit breaker is off until the solar storage tank is completely filled.
We recommend the use of a 115-volt differential control with a factory installed six-foot line
cord. The installation requires one 115-volt outlet to be installed near the solar storage tank.
Plug the control into the outlet. The circulation pump line cord is plugged into the receptacle on
the side of the controller. A 230-volt control and circulation pump may be substituted, but
troubleshooting the components in the future becomes more difficult. The specified differential
thermostat is the Goldline model GL-30-LCO.
T
HERMOMETERS
Locate two thermometers; one at the supply line and one on the return line of the solar loop so
that the temperature rise across the collector can be determined.
L
ABELS
Label installation is mandatory at several locations of the system. Please insure compliance by
affixing labels at the designated locations.
