The collectors are identified by one sticker. On this sticker all the
details of the collector are written. The information
provided on the sticker is important for the future identification of
the product.
INSTRUCTIONS FOR THE INTERCONNECTION OF COLLECTORS
In a central collector bank, the maximum number of collectors, must not be greater than seven-eight (e.g. 14-16m
2
)
per row. The maximum number of collectors shouldn´t be greater than four-five per row in case of using a Drain Back
system. The collector banks must be connected in parallel between themselves and at a distance of 90cm (when at
an angle of 25°) to 120 cm (when at an angle of 40°). At the beginning and the end of each line, there must be a valve
and a 3/4” x 1/2” x 3/4” T-piece for the installation of a submersible thermometer. In addition at the end of the last row,
the differential thermostat sensor must be placed in place of the collector’s sensor (Ø8).
RECOMMENDATIONS ON HEAT TRANSFER MEANS AND SAFETY AND
PROTECTION MEASURES DURING FILLING, OPERATION AND MAINTENANCE
For the protection of the collectors’ circuit from frost, a solution of water and propylene glycol is used, which is non-toxic,
at a ratio suitable to provide frost protection down to -10° within the collector at an exterior temperature of -20°. Once
the system has been placed and until the installation is complete the glass panels of the collectors must remain covered,
until the boiler is filed with service water, so as to avoid the boiling of the filling liquid or the breakage of the glass.
The system must have the filling liquid replaced or topped up every 2-3 years. The filling must be accomplished with
a suitably diluted liquid. In addition, the circuit needs the provision of a differential thermostat with a sensor for the
protection of the circuit from frost which shall activate the circulation pump when the internal temperature r4°C.
Additionally, under no circumstances must the automatic filling valve be left open, as there is the danger that if the
collector bank has a small leak at some point which is leaking water, the automatic filling valve (if left open) will
continuously top up the system with water and so the ratio of the anti freeze liquid will be altered and the collectors
may break at the first sign of frost.
