For your safety General Every person, who is in charge of the installation work on the Condair EL must have read and understood this installation manual and the Condair EL operation manual before carrying out any work. Knowing and understanding the contents of the installation manual and the operation manual is a basic requirement for protecting personnel against any kind of danger, to prevent faulty operation, and to operate the unit safely and correctly.
Page 8
Preventing unsafe operation All persons working with the Condair EL are obliged to report any alterations to the unit that may affect safety to the owner without delay and to secure the Condair EL against accidental power-up. Prohibited modifications to the unit No modifications must be undertaken on the Condair EL without the express written consent of Condair.
Product Overview Calculating the maximum required steam capacity The maximum required steam capacity must be calculated based on one of the following formulas: V • p • (x oder • (x 1000 1000 • ε maximum steam demand in kg/h volume of supply air portion per hour in m /h (for indirect room humidification) or room volume to be humidified per hour in m /h (for direct room humidification)

5.4.2 Positioning of the steam distributor The location of the steam distributor should be determined at the time of dimensioning the air condition- ing system. Please note the following instructions to ensure proper humidification of the duct air. Calculating the absorption distance The steam, emitting from the steam distributor, requires a certain distance to be absorbed by the air so that it is no longer visible as steam.
Page 36
Note: If the absorption distance has to be reduced for technical reasons, the amount of steam per unit must be divided between several steam distribution pipes or the steam distribution system OptiSorp must be used. If this is the case, contact your Condair representative. Minimum distances to be observed...

Installation notes The steam distribution pipes are designed for either horizontal installation (on the duct wall) or, with ac- cessories, for vertical installation (in the duct floor). The outlet orifices should always point upwards and at right angles to the airflow. If possible, the steam distribution pipes should be installed on the pressure side of the duct (max. duct pressure 1500 Pa).

Notes on humidity control systems/humidity control 5.6.1 System 1 – Room humidity control System 1 is suited for direct room humidification and air conditioning systems with mainly recir- culated air. The humidity sensor or humidistat respectively is preferably located in the room itself or in the exhaust air duct.
5.6.3 System 3 – Supply air humidity control with continuous output limit ation Supply air humidity control (humidity sensor installed in supply air duct) should be used only where room humidity control is impracticable for technical reasons. Such systems always require a PI-controller.
DANGER! Danger of electric shock The Condair EL is mains powered. Live parts may be exposed when the unit is open. Touching live parts may cause severe injury or danger to life. Prevention: The Condair EL unit must be connected to the mains only after all mounting and instal- lation work has been completed, all installations have been checked for correct workmanship and the covers are closed and fastened properly.
