Electrical Wiring - BWT ET-NU25 Notice D'installation Et Conseils D'utilisation

The heat exchanger was originally designed for a pool water flow from left to right.
The water from the boiler enters from the left, flows through the heat exchanger in the opposite direction
to the pool water and exits on the same side lower down.
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 invert 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.
