storage cylinders are delivered wi-
thout a boiler heating pump. A suitably rated pump
must be provided and installed separately. Flow rate
from the solar collector circuit depends on the type
and number of collectors installed. For further infor-
mation, consult the manual for the collectors.
b
The domestic hot water system MUST INCLUDE an
expansion vessel, safety valve, automatic vent valve
and storage cylinder drain cock.
b
Safety valves must be connected to a suitable col-
lection and drain system. The manufacturer declines
all responsibility for damage caused by water esca-
ping from safety valves.
b
The choice of system components and the method
of their installation are left up to the heating engineer
installing the system. Installers must use their exper-
tise to ensure proper installation and functioning in
conformity to all applicable legislation.
b
Circuits filled with anti-freeze must be fitted with water
disconnectors.
b
If the water supply is unsoftened, avoid setting the
maximum temperature of the storage cylinder above
60°C, since higher temperatures can lead to the for-
mation of more lime scale and consequently poorer
thermal exchange efficiency.
b
Make sure that the storage cylinder is full of water
before starting up the solar heating system.
