3.3 Heat pump module
The refrigeration circuit is "hermetically sealed". It contains the
Kyoto protocol approved refrigerant R410A with a GWP value of
1975. It is CFC-free, does not deplete ozone and is non-flamma-
ble.
The heat pump module switch box contains all components re-
quired for operating the refrigeration circuit.

4.1 Brine circuit manifold
The brine circuit manifold combines and connects the individual
collector or exchanger loops to create a main line connected to
the heat pump. The built-in ball valves can be closed off individ-
ually for de-aerating or emptying the brine circuits.
Fig. 4.1: Set-up of the brine circuit manifold or collector
The collector or heat exchanger pipes must be inserted into the
manifold from below in a bend (without tension), so that it is pos-
sible to compensate any length differences occurring between
the summer and winter months (tension cracks).
