installed at the lower side of the collector(s) and the
other edge at the filler neck of the bottle, as long as we
have already lifted the bottle and the plastic tube (
L
) at
the same height with the water tank (
photo 4
). Then
we start filling up the closed circuit (loop) with the
thermal fluid of the bottle and when it will be finished
we continue filling it up with water until the water tank
will run over from the tube at the side (
N-08
), which
means that all of the air has come out, the closed
circuit is filled up and we can screw the security valve
finally. At the end, as long as we have checked very
carefully all of the connections for any possible
leakages, we position the protection side cover of
aluminium (
J
) as at (
photo 2
) and the protection
middle cover of aluminium (
K
) in case of 2-3 collectors
as at (
photo 3
), and finally we place the boiler
security straps (
M
) (

) that we have to screw
in the jam nut M8 at the front side of the horizontal
B
support angle and the back side of the long bracket
support
