Operation The Condair RS steam humidifier may be commissioned and operated only by persons familiar with the Condair RS steam humidifier and adequately qualified. It is the owner’s responsibility to verify proper qualification of the personnel. First-time commissioning The first-time commissioning must always be done by a service technician of your Condair representative or a well trained and authorized person of the customer.
7.2). If the function check on the level unit is successful, the Condair RS will be in normal operating mode and the home screen is shown. The heating current switches on as soon as the humidity controller/ humidistat demands humidity. The LED lights green and steam is produced after a short delay.
Notes on operation 4.4.1 Inspections during operation During operation the Condair RS and the humidification system have to be inspected weekly. On this occasion check the following: • the water and steam installation for any leakage. • the steam humidifier and the other system components for correct fixing and any damage.
In order to stop the drain cycle, press the <Cancel> button in the drain progress window. The drain cycle is stopped, and the home screen is shown again. 5. If you have to carry out work on the Condair RS, switch off steam humidifier via the unit switch. Otherwise the steam cylinder(s) is/are immediately filled again.
Taking the unit out of operation In order to take the Condair RS steam humidifier out of operation (e.g. for maintenance purpose), per- form the following steps: 1. Close the shut-off valve in the water supply line. 2. If applicable: Stop the RO-E pure water system according to the separate Condair RO-E installation and operation manual.
Operating the Condair RS control software Home screen After switching on the Condair RS and the automatic system test has been passed the Condair RS is in normal operating mode and the home screen is shown. Note: The appearance of the home screen depends on the current device and error status and the con- figuration of the humidity/temperature control of the system.
Device Status Cyl. A/B: Shows the current status 18:04 18:04 02.04.2024 02.04.2024 of steam cylinder A and B of the Condair RS. Home Status Note: Device Status Cyl. B only appears on large Device Status Cyl. A and double units.
