Typical installation schematic
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 formation 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.
b
If the storage cylinder is installed in systems that
operate at pressures in excess of 4 bar, fit a pres-
sure reducer.
b
Take care when opening the solar heating circuit’s
vent valve. Risk of burns!
b
Make sure that the expansion vessel is able to with-
stand high temperatures and that its membrane is
resistant to the water-glycol mix.
b
The domestic hot water system MUST INCLUDE
an expansion vessel, safety valve, automatic vent
valve and storage cylinder drain cock.
b
The safety valve must be connected to a suitable
collection and drain system. The manufacturer
declines all responsibility for damage caused by
water escaping from the safety valve.
b
Use a thermostatic mixer valve (19) to limit the
domestic hot water outlet temperature.
b
If the pressure in the solar heating circuit drops, do
NOT top up with water but use the proper water-
glycol mix. Risk of freezing!
b
All piping, collectors, heat exchangers and other
devices in the circuit must be subjected to proper
hydraulic seal testing.
b
The choice of system components and the method
of their installation are left up to the installer.
Installers must use their expertise to ensure proper
installation and functioning in compliance with all
applicable legislation.
