3. The conduit or tubing is terminated in fittings approved for
grounding.
WARNING
Never use this solar water heater unless it is completely full of
water.
WARNING
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.
CAUTION
If wiring from the fuse box or circuit breaker box was aluminum
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 electrician.
FIGURE 6
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 6.
WARNING
INSTALLATION IN RESIDENTIAL GARAGES: The solar water
heater must be located and/or protected so it is not subject to
physical damage by a moving vehicle.
FILLING THE SOLAR WATER
HEATER WITH WATER
1. Close the solar water heater drain valve. The drain valve is
on the lower front of the solar water heater.
2. Open the cold water supply to the solar water heater. NOTE:
THIS VALVE MUST BE LEFT OPEN WHEN THE SOLAR
WATER HEATER IS IN USE.
3. Fill the solar water heater until water runs out an opened hot
water faucet. This will let out air in the solar water heater and
the piping. Close the faucet after the water comes out. You
must not turn the electricity on until the solar water heater is
full of water. IF ANY AIR IS LEFT IN THE TOP OF THE SOLAR
WATER HEATER, THE TOP HEATING ELEMENT WILL BURN
OUT RIGHT AWAY.
4. Check all the new water piping for leaks. Fix as needed.
WIRING OF ELEMENT
Determine voltage and wattage from the rating plate attached to
the solar water heater. All external wiring, connection, and
overcurrent protective devices must be provided and installed
in accordance with the latest edition of the National Electrical
Code, local codes, and local utility requirements. The solar
water heater must be electrically “grounded” by the installer. A
green ground screw has been provided on the solar water
heater’s junction box.
The grounding electrode conductor shall be of copper,
aluminum, or copperclad aluminum. The material shall be
resistant to corrosion, and shall be of one continuous length
without a splice or joint.
Rigid metal conduit, intermediate metal conduit, or electrical
metallic tubing may be used for the grounding means if conduit
or tubing is terminated in fittings approved for grounding.
FIGURE 5
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.
