Nature's Comfort SunMor SM-V30 Installation Manual - page 4
• Off the extra port from the auto-fill valve, run a line to drain water that overflows from heat expansion to a desired
area.
• Run a line from the left copper coil heat exchanger port to the cold water input of your domestic water heater.
• All water lines must be super insulated using closed-cell foam insulation. Heat tape will be necessary to install BEFORE
you insulate. Use a heat tape that has a thermostat so it will only turn on if it gets cold to save energy.
• Plug any unused port that are left.
• ONLY INSTALL THE GLASS TUBES AND FILL WITH WATER BEFORE DAYLIGHT. Doing so at any other time will cause
the glass tubes to shatter due the extreme temperature difference of the glass tubes reaching over 400 degrees
being hit with unheated water. Heat is still produced on cloudy days and if empty, the tubes take a long time to cool
down after dark! The other option is to have the water lines installed first and water turned on for the auto-fill valve
to let water flow and fill a tube right as it is installed. Keep the glass tubes completely covered from sunlight until
ready to immediately install.
• Before inserting a glass tube into the manifold, coat the end with soapy water before and after putting the black
rubber trim ring on and also coat the manifold gasket for ease of installation. Carefully install each tube into the
manifold by twisting and pushing in to the manifold as straight as possible. Use controlled, firm pressure. The tubes
will suddenly slide easily once fully pushed though the manifold gasket. Use extreme caution not to insert too far so as
to bump into copper coil heat exchanger causing glass to shatter.
• Using the same twisting method, pull to seat the tubes in place in the black plastic cups on bottom end of the frame.
Slide the cups left or right to keep tubes evenly spaced.
Additional Safety Notes, Installing Multiple Systems
• The SM-V30 is a non-pressurized system only and must always be vented and water pressure continually on at the
auto-fill valve to keep the storage tank full of water.
• Keep snow cleaned off the glass tubes using only a soft bristle brush. Never use hard tools or scrapers!
• For those who have larger demand that want to use multiple SM-V30 systems, put the domestic lines to and from the
copper coil heat exchangers of the SM-V30’s in series. Install the line to the auto-fill valve as usual (hot water from the
first system is permitted for auto-filling the next system).
• You must install a water tempering (mixing) valve on the hot water out of the domestic water heater to prevent
scalding water (available from Nature’s Comfort).
Enjoy your free hot water!
