storage cylinders are delivered without 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 information, consult the manual for the collectors.
b
The domestic hot water system MUST INCLUDE an expansion vessel, safety valve, automatic vent valve and stor-
age cylinder drain cock.
b
Safety valves must be connected to a suitable collection and drain system. The manufacturer declines all responsi-
bility for damage caused by water escaping 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 expertise to ensure proper installation and functioning in conformity to all ap-
plicable legislation.
b
Circuits filled with anti-freeze must be fitted with water disconnectors.
