INITIAL STARTUP
Checks and preparations for initial start-up
Fill the storage cylinder with (potable) water.
Fill the solar collector circuit.
Make sure that the domestic cold water inlet
cock is open.
Make sure that the safety valves are
functioning.
Check the system for leaks.
Check the concentration of the anti-freeze.
Uncover the solar collectors and clean them if
necessary.
Make sure that the system is securely fixed to
the mounting frame.
Make sure that the roof does not leak.
Inspect the insulation.
MAINTENANCE
b
The solar water heating system must be serviced periodically by
T
’s Technical Assistance Centre or by a
qualified heating engineer.
b
The system should be serviced at least once a year, ideally in the autumn.
b
Check the condition of the magnesium anode.
Visually inspect the collectors for damage/dirt.
Visually inspect the storage cylinder.
Visually inspect the mounting frame and roof
anchor points.
Inspect the insulation.
Make sure that the roof does not leak.
Make sure that the safety valves are
functioning.
Check the system for leaks.
Check the concentration of the anti-freeze.
Check the pH of the anti-freeze with litmus
paper.
Topping up or changing the heat transfer
liquid
Clean inside the storage cylinder (every 2
years or more frequently in hard water/high
temperature areas)
Checking the heat transfer liquid
- Use an instrument like a refractometer or densimeter to check the density of the anti-freeze. If the value is below that
necessary to protect the system at the minimum temperature selected, replace the heat transfer liquid or add anti-freeze.
- Use litmus paper to check the pH (nominal value approx. 7.5). If the measured value is below 7, change the heat transfer
liquid.
