SAFETY INSTRUCTIONS TO FILL THE TANK
Essential instructions for the safety of persons and the environment
• The DHW tank must always be filled and pressurised before filling and
pressurising the primary circuit.
• Do not use vehicle antifreeze. This can cause serious injury or death, or damage
facilities.
• If antifreeze is needed in the primary circuit, it must comply with Public
Hygiene Regulations and must be non-toxic. A food-grade Propylene Glycol is
recommended. It must be diluted according to the ratio recommended in the
local regulations.
• Consult the manufacturer to determine the compatibility of the antifreeze with
the tank's construction materials.
Essential instructions for the correct operation of the system
• Before bringing the tank into service, check the connections to avoid any risk
of leaks during filling.
• Only use drinking water to check that the DHW tank is watertight. The on-site
test pressure must not exceed a pressure surge of 8,6 bar.
• Using antifreeze in the primary circuit will lead to a reduction in the heating
performance. The higher the concentration of antifreeze in the circuit, the lower
the performance.
