Introduction 1.1 Notes on the operating instructions Limitation These operating instructions are an addendum to the installation, commissioning and service instruc- tions for the Condair GS C series and for the Condair GS...OC C series and describe the operation of the Condair GS/GS...OC - C series control. These operating instructions are meant for well trained personnel being sufficiently qualified. Safekeeping Please safeguard these operating instructions in a safe place, where they can be immediately accessed. If the equipment changes hands, the documentation must be passed on to the new operator. If the documentation gets mislaid, please contact your Condair supplier. Language versions These operating instructions are available in various languages. Please contact your Condair sup- plier for information. Copyright protection The present operating instructions are protected under the Copyright Act.

2.2 Switching on and off the Condair GS/Condair GS...OC Note: For putting the Condair GS/GS...OC into operation and out of operation please follow the procedures described in the chapters 7. and 7.4 of the installation, commissioning and service instructions for the Condair GS/Condair GS...OC. • Switching on the Condair GS/Condair GS...OC: • Switch on the external service switch in the power supply line. • Switch on the unit via the unit switch. The control carries out a system and level test, during which all the LEDs Condair GS 240 light up.
Interrogation functions 3.1 Interrogation of the operating information in the indication level In the normal operating mode the operating and display unit is in the indication level. The indication level forms a loop that includes several pages holding operating information which can be accessed with the arrow keys. The various displays of the indication level are shown below. Info page 1: Standard operating display The appearance of the standard operating display (info page 1) depends on the actual operating status and the configuration of the Condair GS/Condair GS...OC. The following displays are possible.

Press the <Yes> key. The tank draining starts. During the tank drain cycle the display confirms the tank is drained along with the time remaining to complete the cycle. A corresponding message is displayed when the tank is empty. To interrupt the drain cycle press the <Stop> key. Press the <Esc> key several times to quit the tank draining function and to return to the standard operating display. 5.5 Performing the tank pre-clean function With the tank pre-clean function you can initiate a tank cleaning cycle. The tank pre-clean function activates the drain pump in order to drain the tank for a fixed time (depending on unit size), then the fill valve is activated to partially fill the tank with cold water. Upon completion of the fill cycle the tank is drained once again. This removes any accumulated minerals and cools down the tank for maintenance.

Fault elimination 6.1 Fault indication Malfunctions during operation are indicated by a corresponding Warning or Fault message in the display of the control unit (each warning and fault message is stored in the error list): – Warning messages (additionally to the warning message the red LED flashes) Warning IMW-1:Ignition Module Menu Info Further operation is still possible. The control of the Condair GS/Condair GS...OC checks whether there is a temporary problem (e.g. gas supply interrupted for a short time) or whether it can re- solve the problem by taking necessary measures. If the cause of the malfunction disappears of its own accord or if the control can repair the malfunction, the alarm message will automatically switch off. If the cause of the malfunction does not disappear even after a longer period of time, a fault message is triggered. – Fault message (additionally to the fault message the red LED lights) Fault OTF: Over Temperature Lockout Menu Info Further operation is not possible any longer, the unit is blocked. To eliminate the malfunction see chapter 6.. Note: After eliminating the malfunction the fault message must be reset (see chapter 6.4).
