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installation

• 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.
