Hydraulic System Connection - Rotex A1 BG Installation And Maintenance Instructions Manual

Hydraulic system connection

Fig. 8-5 and fig. 8-6 show examples of the integration
of a Sanicube INOX hot water storage tank and a sub-
tank US 150. Note that the hydraulic circuit shown does
not claim to be complete and your system planning
must therefore still be carried out thoroughly.
As a ROTEX certified company you will find other ex-
amples for hydraulic system connection concepts on
the ROTEX Homepage.
