Ferroli assumes no responsibility or liability for any errors or inaccuracies that may appear in this manual, including the products and functions described in it.
Any other use is considered improper. AQUASOL INSTALLATION MUST ONLY BE PERFORMED BY QUALIFIED PERSONNEL, IN ACCORDANCE WITH ALL THE INSTRUCTIONS GIVEN IN THIS TECHNICAL MANUAL, THE PROVISIONS OF CURRENT LAW, THE RECOMENDATION OF BS STANDARDS, ANY LOCAL REGULATIONS AND THE RULES OF COMPETENT WORKMANSHIP.
• Suitability of the wall to support the unit (see paragraph 6.2) The following clearances are required for maintenance purposes: Top view 50mm 500m 50mm 150mm >600mm 400mm Side view Front view M 1261-06-X AquaSol Ferroli Installation Manual.doc July 2006 Page 5 of 24...
Note: if the AquaSol is not mounted on a solid wall, adequate precautions should be taken to ensure that the fixings are mounted into the battens of the wall and that these are of sufficient strength to support the 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.
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.
7.4 Ferroli AquaSol Solar Drain-back system Solar flat plate collector. For maximum exposure the collector should face Southeast to Southwest at an angle of 35° (Minimum angle 25° maximum angle 60°) Maximum 4mtr head AquaSol cylinder with integral drain-back. T&P Flow from Collector 10mmØ...

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.
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.
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.
Note: The discharge will consist of scalding water and steam. Asphalt, roofing felt and non-metallic rainwater goods may be damaged by such discharges. M 1261-06-X AquaSol Ferroli Installation Manual.doc July 2006 Page 15 of 24...

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.
9.3 Flushing the System To flush the system, drain the system as per instructions 9.2. Refill the system as per instructions 8.1, This may be required several times if heavily contaminated. M 1261-06-X AquaSol Ferroli Installation Manual.doc July 2006 Page 20 of 24...
400 seconds, following which it will switch to solar radiation dependent lower speed. The pump will be switched off as the AquaSol reaches a temperature of 85°C. After this the collector circuit will drain and prevent the AquaSol from overheating.
Pump does not switch on within 30 days a. Check the operation of both collector and lower cylinder sensors (Tabel 2) b. Check that the collector sensor is in contact with the absorber plate M 1261-06-X AquaSol Ferroli Installation Manual.doc July 2006 Page 23 of 24...
