INSTALLATION INSTALLATION SAFETY INSTRUCTIONS General remarks • Connections (electrical, hydraulic) must be carried out in accordance with applicable standards and regulations. • If the water drawing off point is far from the tank, installing an auxiliary DHW loop can allow to get hot water more quickly at all times. Essential instructions for the correct operation of the system •... - Page 14 The upper hot water layer may then reach very high temperatures. • ACV recommends using a pre-set thermostatic mixing valve in order to provide hot water at a maximum of 60°C. • Water heated to wash clothes, dishes and for other uses can cause serious burns.

Page 18: Starting Up
STARTING UP SAFETY INSTRUCTIONS TO FILL THE TANK Essential instructions for the safety of persons and the environment • The DHW tank must always be filled and pressurised before filling and pressurising the primary circuit. • Do not use vehicle antifreeze. This can cause serious injury or death, or damage facilities. -
Page 19: Filling
STARTING UP FILLING Essential instructions for the correct operation of the installation • The DHW tank must always be filled and pressurised before filling and pressurising the primary circuit. FILLING THE DHW TANK (Figure 1) General remark • Connect the safety valve outlet to the sewer. To fill the tank, open a hot water tap (2) located at the highest point of the installation. - Page 20 STARTING UP FILLING THE PRIMARY CIRCUIT (Figure 2) Check that the drain valve (3) of your primary circuit is tightly closed. Open the stop valves (1) and (2) of the primary circuit connected to the heating boiler. Open the air bleed valve (4). In addition, follow the filling instructions provided with the heating boiler.

Page 22: Maintenance
MAINTENANCE PERIODIC CHECKS BY THE USER • Check the pressure of the primary circuit pressure gauge: it should be between 0.5 and 1.5 bar. • Visually inspect, on a regular basis, the valves, connections and accessories in order to detect any leaks or malfunction. - Page 23 MAINTENANCE DRAINING THE PRIMARY CIRCUIT (Figure 3) Before draining the DHW circuit, isolate the tank and lower the pressure of the primary circuit to 1 bar, in order to prevent the DHW tank from being crushed. To drain the primary circuit of the hot water heater: Isolate the water primary circuit by closing the stop valves (1).
