FA ROTEX Solaris RPS4 - 06/2015
8 x Hydraulic system connection
8.2 Connection of a pressure solar panel
system
If the structural conditions do not permit mounting the solar
panels above the storage tank, or if the connecting line cannot be
installed with a continuous gradient between the solar panel and
the storage tank, you cannot use the depressurised ROTEX
solar system (DrainBack) and thus the Control and pump unit
RPS4.
Instead, the heating system can be executed with the ROTEX
solar pressure system. The following solar components can be
used equally in both systems:
Ɣ Solaris high-performance flat solar panels V21P, V26P, H26P
Ɣ Solaris on-roof, flat-roof and in-roof mounting packages
Ɣ Solaris hot water storage tank
Other system components must only be used under system-spe-
cific conditions.
