The heat exchanger is configured for a pool water flow from left to right.
Water from the boiler enters the heat exchanger on the left hand side, and exits via the circulator further
up on the same side.
The temperature sensor is inserted into the recess on the left-hand side of the heat exchanger (at the pool
water entry point).
To invert the direction of water flow, do the following :
• Unscrew both of the 3 part unions on the circulator and swap them. Screw the 3 part unions back together.
• Take the temperature sensor out of the housing on the left-hand recess and insert it into the corresponding
recess on the right hand side.
