IMPOrTANT
It is essential that the Dhw cylinder is filled and pressurised
before filling the heating circuit.
Pressure reducer
If the water mains pressure is greater than 6 bar, a pressure reducer calibrated
to at least 4.5 bar must be fitted (UK regulations apply).
hot water safety valve
The hot water safety valve is at 7 bar; valve discharge must be connected to
drain (UK regulations apply).
hot water expansion tank (as standard on Pro Pack, 2 litres)
Installing a hot water expansion tank avoids any risk of pressure surges due to
water hammer or pressure variations.
Optional hot water circulation
If the tank is situated a long way from the point of use, then installing a closed
return circuit can provide a faster supply of hot water at all times.
IMPOrTANT
As a safety measure against burns, we strongly
recommend installing a thermostatic mixer.
INstaLLatIoN
optional fittings available
Pressure reducer Ø 3/4"
Temperature mixing valve Ø 3/4"
Expansion tank 5 litres
If there is a risk of low pressure in the hot water circuit
(installation of a Delta Pro & Pro Pack on the roof of a building),
it is essential to install a vacuum breaker device onto the cold
water supply.
