Essential instructions forthecorrect operation ofthesystem

• The tank must be installed in a dry and protected area.

• Install the appliance to ensure easy access at all times.

• To avoid any risk of corrosion, connect the stainless steel tank directly to the earth.

• Make sure to install a pressure reducing valve set at 4.5 bar in the DHW circuit if the

supply pressure is higher than 6 bar.

• On the DHW circuit, install an approved safety group, comprised of a safety valve

set at 7 bar, a check valve and a stop valve.

• Make sure that the outlet of the safety unit goes directly to the sewer to avoid any

potential damage.

• Do not install the safety group above the tank to avoid water discharge on to the

tank.

• Make sure to install a domestic expansion vessel of the appropriate size to avoid

discharge from the safety valve (loss of water). Refer to the expansion vessel

manufacturer’s technical instructions for more details.
