To maximize the performance of the Pool Exchanger Line of heat exchangers, the product should be installed in a counter-current flow method, as shown below in Figure 1 below. The hot, or heating, fluid flows through the tube side. The cold, or heated, fluid flows through the shell side.
Example: for swimming pool applications, the pool water is to flow through the shell side, and the boiler water is to flow through the tube side.

The Pool Exchanger Line come with mounting brackets to assist in their installation and ease of use.
Under no circumstances should there be any pulsating of fluids in the system, this causes vibrations that could damage the structural integrity of the pool exchanger. The system should be designed to prevent the unit from encountering pressure shocks and rapid temperature changes.
