2.2.2.2

ACV circulation kit

ACV offers an optional pre-assembled circulation kit comprising:
- a circulator.
- a 3-way manual motorisable valve.
- connecting pipes including a second optional circuit.
- two isolating valves.
- adapters for mounting expansion tank, safety valve and filling

valve to right or left.

2.2.2.3

Discharge

The drain valve and safety valve must be connected to the waste
water system in accordance with current regulations.

2.2.3

DOMESTIC HOT WATER CONNECTION

2.2.3.1

Pressure reducer

If the water mains pressure is greater than 6 bar, a pressure
reducer calibrated to 4.5 bar must be fitted.

2.2.3.2

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
system in accordance with current regulations.

2.2.3.3

Hot water expansion tank

Installing a hot water expansion tank avoids any risk of pressure
surges due to water-hammer.

2.2.3.4

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 always available.

2.2.3.5
