Page 3: Safety Measures
- Do not carry out repairs on components that have safety functions. These must be periodically checked and, if necessary, replaced. - Components must only be replaced using Thermics Energie original spare parts. Failure to do so will void the warranty.
Page 4 - Installation must only be carried out by qualified personnel according to the national and regional regulations in force. - Only use the fixing systems provided for the Thermics Energie collectors and read the current regulations provided in these instructions in order to install them correctly.

Panel description g. Suggestions regarding sizing Reference can be made to some general guidelines for the sizing of small Thermics Energie solar systems as a starting point for the detailed executive design that the system, designer or qualified professional technician should carry out according to current technical practices and legislation: - Solar collector orientation;...
Page 10 Thermics Energie technicians. Solar filed reference flow rate The nominal flow rate of Thermics Energie panels is established by considering a value from 0.6 to 0.85 l/min per sq.m. The circulation unit also has to be selected and sized accordingly, considering the area of the solar surface installed, the pressure drops of the solar field and the circuit (local and distributed).

Page 13: Transport And Handling
- There should always be a certified safety valve in the solar circuit. All Thermics Energie solar stations and modules are fitted with a certified safety valve. Also install a metal drain at the outlet of the safety valve in a special brass container as per regulations.
Page 14: Choice Of Hydraulic Connection And
Panel installation j. Choice of hydraulic connection and examples Thermics Energie panels can be connected in series in a battery having a total surface area up to 35 sq.m. The hydraulic inlet and outlet connections to the panel can be installed one on one side and one on the other, either on the right or left, or both on the same side, either right or left.

Panel maintenance and repair Charging the solar circuit and putting it into operation It is recommended to use Thermics Energie Mayline FSP transfer fluid in order to prevent freezing or corrosion of the solar pipework. Mayline FSP is a glycol-based fluid specially designed for evacuated tube thermal solar collector applications.
Page 37 Panel maintenance and repair - Filling the boiler: Open the utilities hot water tap and leave it open, open the mains water inlet to the boiler and fill it. Once the boiler is completely full, close the utilities hot water tap and wash the solar circuit.
Page 38 Panel maintenance and repair Connect the delivery (filling) and return (drain) lines to the filling and drain valves (5-9). Close the ball valve (10) by turning it clockwise, open the filling valve (5) and drain valve (9) and add the Mayline FSP antifreeze by turning on the charging pump so that it circulates in the same direction as for normal operation.
