4.2.3 Hydraulic connection
1. Only with connection of a HybridCube hot water storage tank
to a ROTEX heat pump:
Ɣ
ROTEX Mount the storage tank kit "E-PAC" for the
ROTEX heat pump to the HybridCube hot water storage
tank (see the individual installation and operating instruc-
tions included for the storage tank connection kit).
2. When using
circulation brakes
, fit them into the pipe
connections on the ROTEX Sanicube / HybridCube.
3. Connect the drain hose to the connector of the safety
overflow (fig. 4-4 to fig. 4-7, item 14) on the hot water storage
tank.
– Use transparent drain hose (draining water must be visi-
ble).
– Connect the drain hose to an adequately dimensioned
waste water installation.
– Drain should not be lockable.
4. Check the water pressure at the cold water connection
(<6 bar).
Î
If the pressure in the domestic water supply is greater
then fit a pressure reducer and limit the water pressure to
<6 bar.
5. Create connection of the cold water inlet to the hot water
storage tank (fig. 4-4 to fig. 4-7, item 1).
6. Connect the connections to the hot water distribution network
(fig. 4-4 to fig. 4-7, item 2).

Installation of drain hose at safety overflow
In order to be able to flush out the stainless steel corru-
gated heat exchanger for domestic hot water heating in
the event of bad water quality, install a removal facility
to each of the cold water and hot water connections on
the storage tank (T-piece with draw-off cock).
Above a hardness level of >3 mmol/l we recommend
also fitting a dirty water filter that can be back-flushed
into the cold water connection.
