Troubleshooting
The following are the only failure possibilities of the Sol-Reliant drain back system:
System not turning on when sun comes out: This is most likely a bad connection between the
solar PV module and pump. Modules almost never fail. The pump has more than a 20-year
lifetime.
Pump is running but the flow meter indicates there is no flow. This is usually caused by a
loss of operating fluid indicating either a leak somewhere in the solar loop or possibly fluid lost
from pressure relief valve at the collector. Alternatively, the
pump itself may have failed .
System is not shutting off at high limit, System is overheating: The high limit switch may
have failed. Turn the system off (see page 9, “Toggle Switch and High Limit Switch,” for the
location of the On/Off switch) and run hot water out of any faucet in the building for a few
minutes. Call your solar contractor. NOTE: Water coming from the tap will not be hotter than
the setting on the tempering valve.
Hot water coming into the house is too hot: This may be a problem with your thermostat
setting on the auxiliary heating element or the setting on the tempering valve. Try adjusting the
tempering valve to desired temperature.
Hot water coming into the house is lukewarm : This may be a problem with your thermostat
setting on your auxiliary heating element or the setting on the tempering valve. Try adjusting the
tempering valve to desired temperature.
Re-roofing
The Sol-Reliant was designed to require the minimum possible time to disconnect and remove
for re-roofing.
STEP 1: Turn the pump switch to “OFF”.
STEP 2: Drain 2-3 gallons of solar heat exchange fluid into a container that can be stored. Drain
from the low point solar loop hose bib below the pump near the solar tank.
STEP 3: Loosen the copper unions on the solar pipes at the collector. Be sure to use two
wrenches and apply equal and opposite pressure so as not to torque and twist the pipe.
STEP 4: Disconnect the electrical connections to the photovoltaic module.
STEP 5: Remove the hex head screws that hold the solar thermal collector to the mounting
brackets.
The solar thermal and photovoltaic collector should now be free to lift off and place to the side
so that the area under the collector can be re-roofed. Once the new roof is in, the Sol-Reliant
