1.17 START-UP
The start-up consists of the first filling with water after installation.
Fill with water within 2 months after installation and in any case
only ever remove the covering sheet after the system has been
filled and is stably under pressure.
1.18 ALL THE USES EXCEPT START-UP
If it is not possible to cover with the standard sheet supplied, always
keep the system primed with water and stably under pressure.
1.19 FILLING
- Connect the cold water supply line (from the mains or a well,
etc.) to the inlet connection as indicated in the basic hydraulic
connection diagram.
Note: the outlet connection must be free, if a drainage tap for
venting the system has been installed upstream from the by-pass
valve, this must be opened.
- Open the supply tap and begin to fill the accumulation tank
until the water has filled all the cylinders and the air inside has
been vented through the outlet connection.
Repeat the filling and venting operations several times,
making sure that no bubbles or pockets of air remain
inside the accumulation tank. If any air remains insi-
de it could compromise the correct operation of the
system and even damage the collector itself.
- Allow the water to flow inside the system for a certain
period of time, in order to rinse out any deposits or residues
that could have entered the tank during installation. Convey
the exiting water down the drain.
In any case, it is recommended not to use the water
as “drinking” water for the first two weeks after filling
and putting the collector operation.
- Close the drainage tap upstream from the cold water inlet and
connect the return line to the by-pass valve installed on the outlet
connection, as indicated in the basic hydraulic connection diagram.
- Re-open the cold water drainage tap again, check the correct
installation of all the safety components and also check that there
are no leaks along the supply lines.
Make sure that all the safety components have been
installed according to the instructions in the basic
hydraulic connection diagram before opening the
water supply and putting the system into operation.
- Lastly, turn on the hot water tap to check the correct supply of
water and eliminate any residual air in the supply line of the
system.
- After this operation, it will be possible to remove the covering
sheet.
Due to the thermal inertia of the system, the solar
collector with integrated SOLARSMART storage will
take a few sunny days to go to full capacity. Normally
the system will reach temperatures of use after a day
of full sun.
