mode of system operation.
26) Cold Water Dip Tube: See No.16 above.
27) Anode Rod: See No. 18 above.
28) Heating Elements and Thermostats: See No.
19 above. In a two tank system the back-up
electric water heater has two heating elements
and two thermostats.
29) Temperature and Pressure Relief Valve: See
No. 20 above.
30) Isolation Ball Valve: This valve is used in con-
junction with component No. 25 to completely
isolate the conventional water heater in a two
tank system for repair or replacement.
31) Mixing Valve: Automatically blends hot water
from the solar storage tank with incoming city
cold water to an acceptable set point. A mixing
valve must be installed on every SolaRay solar
water heating system.
32) Optional Time Switch: Allows you to manu-
ally turn on or off the auxiliary heating element in
the solar storage tank (single tank systems) or
back-up electric water heater (two tank systems).
The switch also can be preset to automatically
turn on and off the heating element(s) at speci-
fied times each day. A time switch is a highly rec-
ommended option.
11) ESTIMATED COMPONENT LIFE
You can expect a long useful life from the pri-
mary components in your SolaRay solar water
heating system by adhering to the routine service
and maintenance tips provided above.
The SunEarth solar collectors have a design life of
twenty-five to thirty years. The HTF must be
maintained as specified in this manual to maxi-
mize collector life. Photovoltaic modules have
design lives in excess of twenty years. The solar
storage tank should last 10 to 20 years in most
water quality areas by periodically replacing the
anode rod. The 12 volt DC circulating pump
generally runs 20,000 hours before the brushes
or motor require replacement. Like EPA mileage
estimates for automobiles, these component
design lives represent average figures for closed
loop forced circulation systems of this type
installed in the United States.

tion contractor or SunEarth Inc.
