To connect the unit:
The system should only be installed by a suitably qualified and registered installer.
Only compression fittings should be used to connect the unit.
Hot water
Connect the hot water outlet HW, to cold water inlet on the combination boiler.
Connect the hot water outlet of the combination boiler to the supplied blending
valve, which should be set to the recommended temperature of 48ºC or as
required, NOTE care must be taken to prevent scalding from too higher
temperature.
Connect the safety discharge pipe from the tundish, to drain as stated in
paragraph 7.9.
Solar circuit
Connect the solar return SR with 15mm copper tube (the pipe work running
from the circulating pump outlet to the bottom of the solar collector).
Connect the collector-flow CF with 10mm copper tube (the pipe work running
from top of the collector) to the top CF connection on the AquaSol.
NOTE: Both connections to the Ferroli solar collector are at the bottom
of the unit and flow and return can not be mixed up. The flow
connection is 10mm, the Return connection is 15mm.
Always keep in mind the drain-back level of the Solar storage system. Always install
the collector in a level plain the flow & return must be mounted with an angle of
30mm/m or greater.
The flexible connections of the collector must be installed with the same angle
>30mm/m. The collector itself must be mounted level on the roof.
Install the collector as close to the AquaSol storage unit as possible to prevent extra
heat loss.
The maximum height between drain-back level and top of the collector is
dependent upon the solar pump in the AquaSol storage unit. Therefore the
maximum height is 4m. It is advised to install a separate drain-back tank in case
this is more than 4m. See paragraph 7.7 and ask your supplier.
The manufacturer is not responsible for damage caused by not following the provided
installation instructions or poor installation work.
