We recommend bypassing the heat exchanger while adjusting water chemistry. Stabilize chemistry to a pH of 7.2 - 7.8, with chlorine residual at 1.0 to 3.0 ppm. Damage to the heat exchanger due to improper water chemistry is not covered under the warranty.

Engineers must determine whether this system will work in each application and must ensure compliance with code requirements. Due to the high temperature at the heat exchanger connections, we recommend installing a stainless steel nipple (10" long) on the pool supply and return lines. Seal all threaded connections with an appropriate pipe dope. Perform a leak test to verify all joints. 636-000-043/0199...
