Page 18: Safety Instructions For The Installation
InstallatIon safety instrUctions for the installation General remarks The connections (electrical, flue pipe, hydraulic) must be carried out in accordance with current standards and regulations in force. 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. - Page 19 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.

Essential recommendations for safety The components inside the control panel can only be accessed by an approved installer. -
Page 32: Filling The System
Starting up fillinG the system First put the DHW tank under pressure before pressurizing the heating (primary) circuit. Filling the domestic hot water circuit Open the isolating valves (1) and the drawoff tap (2). Once the water flow rate has stabi- lized and the air is totally evacuated from the system, close the draw-off tap (2). -
