Page 8: Before Connecting This Unit
• Excessive use of flux can damage this unit, especially the check valves. Avoid over-use, and ensure that the system and all pipe work is flushed to BS7593, thus removing all contaminants prior connecting to the AquaSol. • Ensure that the discharge pipe (tundish) and drain valve are positioned away from any electrical components. -
Page 9: Assembling The Unit
Connect the tundish assembly as follows: Connect (1) to the expansion relief valve on the filling manifold (2). Connect (5) to the pressure relief outlet on the AquaSol (6), hand-tighten only. Connect the pump assembly (3) to the collector return (4). Note that the 15mm copper pipe fits inside the 22mm stainless steel pipe. -

Page 12: To Connect The Unit
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. -
Page 13: High Buildings -> Optional Drain-Back Tank
7.7 High buildings -> optional drain-back tank In high buildings (houses) where the difference between the AquaSol and the collector will be more than 4m a separate drain-back tank must be installed in the collector flow. In this way The maximum height difference between collector and AquaSol is expanded to 15m + 4m = 19m. -
Page 14: Electrical Connections
The collector sensor must be connected to the terminals marked COL. Polarity is not important. The AquaSol will give a signal to the Ferroli boiler to prevent it starting up the after heating function if the solar water temperature is above a temperature level of 60°C. -

Page 19: Starting The System
Normal operation If solar radiation is available to heat up the AquaSol the pump will be switched on in high power mode during 400 sec. to purge air from the collector circuit. After this starting up period the pump flow will be adjusted depending on solar radiation and temperature in order to optimize the solar gain of the system. -
