Connect the delivery and return pipes to the circulation unit. Prepare and
connect a suitable expansion tank according to the system design and a
discharge for the safety valve in case any heat transfer fluid comes out.
After the washing, filling, electrical connection and system checking operations,
close the circulation unit with the front casing.

After carrying out the pipe connections, it is advisable to clean the system to
remove any impurities. Proceed as follows:
• close the balancing valve
• connect to the filling connection and run water into the system, making it
circulate until clean water comes out the drain connection
• if water is used for this operation, drain the system via the prepared con-
nection, making sure to force the opening of the non-return valve by turning
the return valve (blue) 45° in closing
• repeat the filling operation, but this time with appropriate heat transfer fluid
(water and glycol max. 50%)
• put all the hydraulic parts of the unit in the working position and activate
the circulating pump.
• open the air vent valve on the delivery side and circulate the fluid for several
minutes, then recheck the circuit pressure: if it is lower than the required
design value, add more fluid and repeat the venting operation.
• once the system is vented, run the pump at maximum speed and adjust the
flow according to the solar collector manufacturer's instructions. The flow
rate is adjusted by means of the balancing valve and the reading on the
respective indicator or with the pump speed selector.
