FILLING THE DHW TANK Figure 1
General remark
• Connect the safety valve outlet to the sewer.
1. To fill the tank, open a hot water tap (2) located at the highest point of the system. It
enables to bleed the air from the system.
2. Open the filling valve (1) and the stop valves (3) to fill the DHW tank.
3. Close the hot water tap (2), after the water flow has stabilised and the air has been
completely evacuated.
4. Check all the connections of the system for leaks.
FILLING THE PRIMARY CIRCUIT Figure 2
General remark
• If the tank is used within a heating system, refer to the heating boiler manual.
1. Check that the drain valve (3) of your primary circuit is tightly closed.
2. Open the stop valves (1) and (2) of the primary circuit connected to the heating boiler.
3. Open the air bleed valve (4) located on the top of the hot water tank.
4. When the air is eliminated, close the airbleed valve (4). Make sure the air bleed valve
is tight.
