How do I troubleshoot or diagnose a system with the APR Control installed, but there are no Isolation Ball Valves?

Diagnosing the system without the isolation ball valves, is extremely time consuming and difficult. Evacuating the system, installing the ball valves, and recharging may be more efficient with your time and eventual accuracy of your diagnosis.

If installing ball valves is not feasible or possible, then consult with our Senior Technical Engineer by calling Rawal Devices (800) 727 – 6447.
