Detailed information thereto can be found in the separate operating instructions for Condair GS control.

9.1 Importantnotesontroubleshooting

QualificationofpersonnelHave faults eliminated by adequatelyqualifiedandtrainedpersonnel only. Malfunctions caused by theelectricalinstallationmustberepairedbyauthorizedpersonnel(e.g.electrician)only.

SafetyWhen eliminating faults, the Condair GS mustbetakenoutofoperation, as described in chapter 7.5, and prevented from further inadvertent operation.Make sure the power supply to the unit is cut off (test with voltage tester) and that the stop valves in the water and gas supply line are closed.

General noteMost operational malfunctions are not caused by faulty equipment but rather by improper installa-tionordisregardingofplanningguidelines.Therefore,acompletefaultdiagnosisalwaysinvolvesathoroughexaminationoftheentiresystem.Often,thesteamhoseconnectionhasnotbeenproperlyexecuted,orthefaultlieswiththehumiditycontrolsystem.
