SELECTION GUIDE The Drain-Unit selection is determined by the height of the installation. Bear in mind the difference in height between the top of the collector array and the bottom part of the Drain-Unit positioning. N.b.: less pump power required if the Drain-Unit is installed just above the collector field. HEIGHT OF INSTALLATION* 3-5 metres 5-10 metres 10-15 metres 3- 10 metres 10-15 metres RECOMMENDED MODEL 6-metre pumps 6-metre + 6-metre pumps 11 + 6-metre pumps 11-metre pumps 11 + 6-metre pumps ECONOMY MODEL 6-metre pumps 11-metre pumps Unfit 11-metre pumps 11 + 6-metre pumps NUMBER OF COLLECTORS** 1-5 1-4 1-4 4-10 4-8 *Height from the top of the solar collectors to the lowest point of the drain unit **Calculated for a collector capacity of 1.25 litres and tube 15 mm. It can be used with installations that have a larger number of collectors than other market alternatives. The volume of the circuit above the drain unit must not exceed 8 litres of working volume of the air separator in drain units with a single tank (or 16 litres for drain units with 2 tanks). Volume calculation in upper part: Volume Nº of collectors Volume of fluid = + + in collector Volume of pipes Solar heating systems 03 DRAIN UNIT WITH INTEGRATED REGULATION • Maximum operating temperature: 110ºC. • Maximum peaks: 130ºC. • Safety valve calibration: 3 bar. • Flow indication range: 2-12 litres/min. • Maximum separation volume: 8 litres. • Connections: bicone nut for a Cu15mm o ½”M pipe. • Control options with pre-connections made. • Consult for adaptability to other regulations.
