Installation Manual for SB32-9PV and SB64-9PV
Do not use the Solar Boiler™ system to heat any treated water system, such as
pools, directly.
Use the proper mixture and quantity of propylene glycol USP and distilled water for
freeze protection.
DO NOT use automotive antifreeze, recreational vehicle anti-
freeze, ethylene glycol, or other poisonous fluids.
Thermo Dynamics recommends
a mixture of 40% Propylene Glycol USP and 60% distilled water for use as the heat
transfer fluid.
The maximum safe working pressure of the Solar Boiler™ system is 60 psi (410
kPa)
System Maintenance
•
Solar Collector Glass:
In some areas the glass plate of the collectors may require cleaning once a year
with an industrial cleaning product. In areas where air pollution is severe, more
frequent cleaning may be required.
•
Back Flushing the Heat Exchanger: (see page 26)
The Solar Boiler™ heat exchanger should be flushed with clean water ever 6
months. First, close the valve at the bottom of the solar storage tank near the
1/2” brass tee that connects the tank to the Solar Boiler™. Second, connect a
hose to the drain bib at the bottom tank tee, and place the free end in a drain.
Open the drain bib and allow water to flow for a few minutes. This will remove
residue from the Solar Boiler™ heat exchanger.
•
Reservoir Fluid Level:
The fluid level in the Solar Boiler™ reservoir should be checked every year.
Instructions for this procedure are part of the refilling instructions. (see page 22)
•
Heat Transfer Fluid (HTF):
The HTF should checked annually. If the HTF is very dark in colour and has a
strong odour, it should be replaced. The extracted HTF should be disposed of at
your local Environmental Disposal Depot.
The pH and freeze protection capability of the HTF should be checked annually.
The pH should not be less than 6. Contact your installer or Thermo Dynamics
Ltd.
With proper system operation and maintenance, the HTF should last between 4
and 15 years without replacement.
