released).
• Check that all circuits are properly sealed.
• Check that the power supply voltage is correct at the mains
switch.
• Check that all hydraulic connections have been properly
tightened and that there are no leaks.
• Check that all the valves are open, that there is water in the
heating circuit and that nothing is stopping the water from
circulating freely in the heat exchanger and the hydraulic circuit.
• Check that the sludge valve is correctly tted and that nothing is
