Important Notes:
1. The diagram shows generic drawings of connections to and from Free Hot Water tank. Follow the specific
instructions of the solar panel supplier for the actual detailed arrangement, components and valves.
2. When using Free Hot Water tanks, solar collectors should be installed in bottom coil (boiler, wetback or
heaters should be installed in upper coil.
3. It is highly recommended running the solar system via the Free Hot Water coil on a close loop arrangement.
Open loop solar is also possible using the Service Circulation port for the solar return instead of the Coil Hot
port, and branching of the Cold Inlet instead of using the Coil Cold port.
4. When connecting commercial solar system, ensure that the energy going through the solar coil is lower
than the max kW rating of the coil as per instructions. Excess energy above the coils rating will void the
warranty.
Warning: Open loop solar carries a frost risk to the panels since antifreeze is not used. This OG300 system
may not qualify for Federal and State rebates if Open Loop method is used.
Commissioning the Solar Tank
VERY IMPORTANT: Prior to turning on any heating application such as solar, boiler or a heater, the tank MUST BE
FILLED UP WITH WATER
1. Make sure that all hot water taps are close off

6. Attend to any other external heating applications
Draining The Water Heater
1. Turn off the power supply of the elements
2. Turn off all external heating applications
3. Turn off cold inlet supply at the 3 in 1 valve or at the meter
4. Open a hot water tap to drain the plumbing
5. Turn off the hot water tap
6. Disconnect the hot water outlet union
7. Open to atmosphere Cold Water Expansion Valve to let water flow via the
8. drain pipe
Water Quality
Free Hot Water SST heater has been manufactured to deal with most qualities of US water supply. Desired water
quality levels: pH Level between 6.5 and 8.5
Chlorides: up to 200 ppm, Total Dissolved Solids (TDS) up to 1000 mg/L
Saturation Index between -0.8 and +0.8
If your water quality or the heating liquids are outside the above range, you
should fit appropriate water filtration.
