EMPTYING THE SOLAR CIRCUIT
If the system requires emptying, perhaps to replace
the solar fluid, proceed as follows:
1
Insert a rubber hose into the drain valve,
place the other end of the rubber hose in
a receptacle large enough to contain the
system solar fluid;
2
open the drain valve
3
open the degasser
[ C ]
on the collectors
to allow air to enter from the highest point
and then empty the circuit more easily;
4
Take the used solar fluid to the tip or to a
specialised incineration facility, in compli-
ance with local regulations.
