ANSWERING AN ALARM

When an alarm condition occurs, the alarm light on the con- trol panel lights. It stays lit until the alarm condition is cor- rected. If you have the optional audible alarm, pressing the Enter button silences the audible alarm.

To find out what is causing the alarm, check the indicator lights on the control panel for the pump and compressor sta- tus. If the pump and compressor are both off, check the water tank level, flow valves, and the pump. If the pump is on and the compressor is off, check the compressor, suction pressure and discharge pressure.
