You must read this entire instruction manual before beginning installation to completely understand system requirements. Aquastats, heat exchangers, mixing valves, pex pipe, pumps, valves and 1” brass pex fittings are all... - Page 2 • The SM-H60 is a solar water heater that uses the sun’s radiant energy to heat water through the use of 60 double wall vacuum insulated glass tubes. Each tri-element glass tube has a coating on the outside of the inner layer of glass made up of nitrogen aluminum to absorb heat on top of a copper coating to transfer and hold in the heat.
- Page 3 If a line freezes, thermo-siphoning cannot take place and boiling can occur, possibly pushing out and breaking a glass tube or a line can break, draining the system which can also result in damage to your SM-H60 or your boiler.
- Page 4 • Keep snow cleaned off the glass tubes using only a soft bristle brush. Never use hard tools or scrapers! • For those who have larger boiler systems that want to use multiple SM-H60 systems, this may only be done by putting the solar heaters in parallel.
- Page 5 Summer Use • For operation when not firing your outdoor boiler, a sidearm HX must be used and utility energy must be turned on for the domestic hot water (DHW) in case of too much demand or not enough sunlight. You must also add a cord end to the aquastat for the boiler pump that must be set to run when the boiler water jacket is 10 degrees or more above the DHW set point and shuts off when it falls to 5 degrees above the DHW set point so utility energy is not used to reverse-heat the boiler.
