SCH Collectors Installation & Operation Manual

2 Location

Array options

For series and parallel connection of multiple collectors, it is advisable to calculate the pressure drop over the entire system with the aid of the enclosed documents and to install an appropriate pump if necessary. The maximum collector area per collector array connected in series is 260 ft2. Be aware of pressure drop, reference the array options (FIG.’s 2-1 and 2-2).
