Connection of the electric immersion heater (booster heater) is
only possible in combination with a ROTEX heat pump. The
installation is to be carried out in accordance with the associated
installation and operating instructions of the ROTEX heat pump
and the individual storage tank connection kit (E-PAC).
4.2.6 Filling the hot water heat exchanger
1. Open the shutoff valve for the cold water supply pipe.
2. Open the hot water tap connections so that the draw-off
volume can be set as high as possible.
3. Once water has been discharged from the tap connections,
do not interrupt the cold water flow; this will ensure that the
heat exchanger will be fully vented and that any impurities or
residue will be discharged.
4.2.7 Filling the storage tank
Without installed solar system
1. Connect the filling hose.
a)
All
