3. Things to Remember
NO TWO INSTALLATIONS ARE EXACTLY ALIKE BUT THERE ARE SOME
GENERAL BITS OF TECHNICAL INFORMATION THAT YOU WILL FIND HELPFUL
IN THE FIELD.
ROOF ORIENTATION:
roof or on an elevated ground mounted rack facing south. The next best orientation is
west and finally east. Collectors should never be installed facing north in the Northern
hemisphere.
FLOW RATES:
The horsepower of your swimming pool filtration pump must be
adequate to supply the solar system with enough water to provide the recommended
flow rate necessary for the collectors being installed. The recommended rates are:
COLLECTOR
UniverSol 32
UniverSol 40
UniverSol 48
AUTOMATIC DRAIN DOWN:
so the water will drain out of them when the pump shuts off. This is especially
important in areas of the country where freezing conditions occur.
For unique roof designs or adverse pool equipment locations, if it is not possible to
achieve complete automatic drain down, manual drain down valves should be installed
in appropriate places in the plumbing or at the end of the bottom (feed) header.
[Instead of installing an end cap at the end of the header, you would place a pipe
connector and reducer bushing along with a 1/2" hose bib].
These valves should be opened when shutting down the system for the winter months
or when freezing conditions are possible. UMA Solar can assist you with the parts
necessary for manual drain down installations.
