9.1. Brazed Plate Heat Exchanger Kits (CL)
a) The brazed plate heat exchanger kits can be used in closed loop systems to heat any suitable storage
tank, instead of using an internal tank coil heat exchanger. All Apricus OG-300 system utilize a 12 plates
dual wall heat exchanger with leak detection. A Grundfos UP 15-29 SF single speed circulation pump is
included as part of the kit and will provide the heat exchanger with a flow rate of ~3gpm.
9.2 Connections
a) The brazed plate heat exchanger kit will be connected to the P2 relay of the Apricus Solar Controller.
For information on systems using this kit and controller settings refer to the Apricus OG-300 Schematics
and Parts List Manual
10. Apricus OG-300 System Designs
Apricus has developed a set of system designs, which represent the most common installation formats. Prior to
installation, ensure the system design meets local codes and regulations. Any modifications to the design during
installation will void the SRCC OG-300 certification and should be checked by a qualified engineer. All systems
must be installed by Authorized Persons. Upon completion of the installation, the system may also need to be
checked by a plumbing inspector prior to commissioning.
A comprehensive set of direct flow and closed loop system schematics are presented in the Apricus OG-300
System Schematics and Parts Lists Manual.
