INSTALLATION CHECK LIST
SOLAR WATER HEATER LOCATION
Choose a location for your solar water heater centralized to the piping system. You must also locate
the SuperStor Contender Solar Water Heater and related domestic piping where it will not be
exposed to freezing temperature. All piping should be insulated. The Solar Water Heater should be
installed so there is access to the element and thermostat for future service. If you do not provide
minimum clearances, it might not be possible to service the water heater without removing it from
the space. The solar water heater should also be placed in a location where T&P discharge or a leak
will not result in damage to the surrounding area. If you do not have this location requirement avail-
able, you must use an auxiliary catch pan.
