Taking out of operation
●
Open the KFE cock on the
KFE filling connection
and drain
the water content of the storage tank.
Only with
solar system
●
Adjust the valve insert on the connection bracket so that the
path to the blind plug is blocked off (fig. 11-5).
●
Place a suitable collecting tray and remove the blind plug
from the connection bracket (fig. 11-5).
●
Insert the
KFE filling connection
in the connection bracket
and secure with holding clamp (fig. 11-6).
●
Open the KFE cock on the
KFE filling connection
.
●
Adjust the valve insert on the connection bracket so that the
path to the drain hose is open (see also fig. 11-5) and drain
the water content of the storage tank.
11.1.2 Draining the heating circuit and hot water
circuit
1. Switch off the main switch and secure against restarting.
2. Close the gas stop valve.
3. Connect the drain hose to the KFE cock of the ROTEX
GCU compact.
4. Open the combined filling and draining valve on the ROTEX
GCU compact.
5. Drain the heating and hot water circuits.
6. Disconnect the heating flow and return flow as well as the cold
water inflow and the hot water outflow from the ROTEX
GCU compact.
7. Remove the thermal insulation from the hydraulic group (see
chap. 4.4.3).
8. Disconnect the hydraulic group/heat cell connection (pull out
the securing stirrup), remove the 3UV DHW 3-way valve and
unscrew the heat exchanger for storage tank charging.
9. Remove the hydraulic group.
10. Connect the drain hose to the cold water inlet and hot water
outlet as well as the heat exchanger for storage tank charging
so that the hose opening is leakproof above the ground.
11. Allow the individual heat exchangers to run empty one after
the other based on the suction lifter method.
12. Put the hydraulic group back on again and re-attach the
thermal insulation (steps 7 to 9 in reverse order).
11.2 Final decommissioning and disposal
For final decommissioning of the ROTEX GCU compact it must
be
●
taken out of service (see chap. 11.1),
●
disconnect it from all electrical, gas and water connections,
●
disposed of in a professional manner.
Recommendations for disposal
The ROTEX GCU compact has an environmentally friendly
design. During the disposal process, the only waste created is
that which can be used for material or thermal recycling. The ma-
terials used that are suitable for recycling can be sorted into indi-
vidual types.

ROTEX has complied with the standards for environ-
mentally-friendly disposal as a result of the environ-
mentally-friendly design of the GCU compact. Proper
disposal in compliance with the respective national
regulations of the country of use is the responsibility of the
