water shutoff valve must be installed above this connection so that water flow may be completely stopped
in the event of a leak, repair, or maintenance.
The hot water output to the house from the tank should be connected to the port labeled "Hot Outlet" on
the top of the tank. Again, a dielectric union must be used where a connection is made between
galvanized and copper pipes. A mixing valve must be installed at this point to limit the temperature of
water delivered to the home.
All hot water lines should be insulated with at least 1/2" thick heat resistant rubber tubing insulation such
as Armstrong Armaflex.
In most instances, the solar collectors can be attached to the roof using the standard mounting hardware
provided with the solar system. Certain types of roofing will require special attention for proper mounting.
For example, a clay tile or cement tile roof. Complete roofing attachment methods of solar collectors for
these various types of roofs are beyond the scope of this manual. The manual will describe and illustrate
some of these approved mounting techniques. A competent contractor should be used to ensure that all
roof penetrations and attachment points are not a source of rainwater leakage later on. Standard
plumbing roof jacks or solar industry copper flashings may be used for plumbing penetrations in most
cases.
The collectors should be canted slightly toward the inlet side to ensure they drain completely when
maintenance is required on the system.
CAUTION!
Photovoltaic modules produce electricity even in minimal sunlight. Keep the PV module covered
during the installation process and when performing system maintenance. The PV system toggle
switch should be in the off position until you are ready to energize the system.
Electrical connections should only be made after the plumbing system is fully installed and ready to be
charged. Insure that the controller or the PV system toggle switch is in the “OFF” position until you are
ready to energize the pump. Remember to remove all collector/module coverings prior to energizing the
system.
NOTE: All collectors are to be mounted vertically, sloped in order to be completely void of fluid when
drained, and oriented in such manner as described below under COLLECTOR LOCATION.
