Page 20: Installation
6 Installation Installation General The following observations must be taken into account for the hydraulic unit installation: 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. - Page 21 6 Installation Assembly 6.3.1 Assembly of the hydraulic unit Importante All units can be mounted on a wall rather than on the tank, as illustrated below. Importante The solar unit must be installed vertically (flow rate direction from the pump going up towards the collector). This installation position means that the thermometers, pressure gauges and flowmeters are easily visible.
