Solar hydraulic unit
The following observations must be taken into account for the hydraulic
unit installation:
Before installing the solar unit, the entire installation needs to be cleaned.
The solar unit must always be installed at a lower level than the collectors
so that no vapour can enter the expansion vessel in case of a blockage.
If the expansion vessel is installed at the same or a higher level than the
solar unit, a heat insulation circuit is required.
The installation must be rinsed with fresh water after each draining
process.
The solar unit is not suitable for direct contact with pool water or solvents.

Once all the hydraulic connections have been completed, check the
sealing of the entire circuit.
It is helpful to protect the collectors from the potential effects of solar
radiation once the packaging has been removed, until the installation
has been filled.
If there is no demand, or it is anticipated that there will be long periods
without any DHW being extracted, it is recommended to protect the
system using thermal blankets.
Once all the connections on the solar control box sensors have been
completed, it is important to check that these do not run across other
electrical cables as this could generate interference and alter the
readout values.
It is recommended to use a shielded cable for the sensor connections.
Atención
Do not use any lubricant or grease on the installation, as this can
damage the seals. Any particles of dirt, grease or lubricant residue
must be rinsed out of the installation prior to installing the solar
unit.
Do not use any solvents to clean the system, as this can damage
plastic parts such as the pump impellers.
