Section 9
General
The Aquavar SPD drives are self-diagnosing controllers. If a problem occurs, observe the Status Code Indicator
Light on the front of the unit. No Status Code Indicator Light means either no or low input voltage (less than
140Vac).
DANGER
Status Code Indicator Light is not a voltage indicator! Always turn off disconnect switch and
circuit breaker and wait 5 minutes before servicing. High voltage may still remain on controller.
Refer to the status code label on the side of the controller access cover to diagnose system errors.
See the following diagram.
