Safety valve
Note! The heat pump must be connected to the expansion tank and the safety valve according to applicable
regulations. The connection between the reservoir and the safety valve must be routed in a continuous
incline. A continuous upwards slope means that the pipe must not slope downwards from the horizontal at
any point.

become damaged. Ensure that system has the necessary pressure, however, not above maximum pressure
of

bar.
