0.5 (bar). Pressure controlled bypass valve EVC 13 is equipped with a pressure controlled bypass valve (48). This is to protect the circulation pump in in- stallations where the radiator flow can completely stop. When the radiator side is closed, the boiler water circulates across the pump internally in EVC 13. -
Page 17: Electrical Installation
The boiler is connected on terminal (9) to 400 V 3- phase, neutral + earth via a distribution board with fuses. EVC 13 does not include an isolator switch on the NOTE! incoming electrical supply. The installation must be preceded by a circuit-breaker with at least a 3 mm Electrical installation and service breaking gap. -
