Connecting the OVB exchanger to the filtration and heating circuit

For connection to the secondary circuit with pool water, the internal 1 1/2" thread is used.
A brass union with a PVC end piece must be connected to it, into which a 50 mm pipe is then
glued. Due to the high temperatures of the exchanger, do not use PVC unions – the thread may loosen and water may leak out!

For connection of the primary circuit with heating water, the internal 3/4" thread is used.

To mount the exchanger on the wall, use the included mounting parts.
