5.3.4 Medium connection in a 4-pipe system
User instructions!
When making a medium connection to the unit, always ensure the correct connec-
tion to the input and output of the heat exchanger! Exchanging the connections can
lead to loss of efficiency! (see
fig. 5-9 and fig. 5-10)
The connection fittings of the heat exchanger always have an inner thread. (refer to
Tab. 5-2)
Pos. 1: Inlet cooling (internal screw thread, see
Tab. 5-2).
Pos. 2: Return line cooling (internal screw thread, see
Tab. 5-2)
Poz. 3: Supply line heating (internal screw thread,
see Tab. 5-2)
Pos. 4: Return line heating (internal screw thread, see
Tab. 5-2)
