INSTALLATION
DOMESTIC HOT WATER CONNECTION
Pressure reducer
If the water mains pressure is greater than 6 bar, a pressure reducer
calibrated to 4.5 bar must be fitted.
Safety unit
The tank safety unit must be ACV approved and calibrated to 7 bar.
The valve discharge must be connected to the waste water disposal
system.
Domestic hot water expassion tank
Installing a domestic hot water expansion tank avoids any risk of
overpressure due to pressure surges and also makes sure that
there is a always water flowing through the safety unit when refilling
the domestic hot water tank.
Hot water circulation
If the tank is located a long way from the point of use, then
installing a closed recirculation circuit ensures that a faster supply
of hot water is always available.

IMPORTANT
As a safety measure against burns, we strongly advise
installing a thermostatic mixing valve (recommended
temperature: 60° C).
