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
storage cylinder drain cock.
b
Safety valves must be connected to a suitable collection and drain system. The manufacturer declines all
responsibility 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
applicable legislation.
b
Circuits filled with anti-freeze must be fitted with water disconnectors.
