4.2 Water Coupling
4.2.1 With circulation
Connect the cold and hot water pipes as well as the
circulation pipe to the hot water module
(Fig. 4.2).
Circulation: 3/4" external thread, high-sealing.
Cold water (blue marking): 3/4" external thread,
flat-sealing.

Important:

Hold the couplings steady when making the connections
to prevent strain on the welded joints!
Hot water (red marking): 3/4" external thread.
Note:
The permitted flow rate in the circulation pipe
Duration of the circulation operation
In accordance with DIN EN 1988 and DVGW
work sheets W551 and 553.
4.2.2 Without circulation
Short-circuit the circulation pipe (1/2" internal
thread) and the hot water pipe (3/4" external thread)
(Fig. 4.3).

4.3 Filling and Venting

Before commissioning, the hot water return pipe
is to be vented at the ball valve (Fig. 4.4) and at
the right-hand T-coupling on the heat exchanger
(Fig. 4.5) until the water is free of air bubbles.

Cold water
Attention! Hold the coupling steady
when making the connection.
