3.4.2 Accessory details 3.4.2.1 DV81-... steam distribution pipe The steam distribution pipes are selected on the basis of the duct width "B" (for horizontal installation) or the duct height "H" (for vertical installation) and the capacity of the steam humidifier. Important! Always select the longest possible steam distribution pipe (opti mum humidification distance).
3.4.2.2 OptiSorp steam distribution system The OptiSorp steam distribution system is used in ventilation ducts with a short humidification distance (for the calculation of the humidification distance refer to chapter 5.4.2). When ordering an OptiSorp system the duct dimension must be specified. Please consult the data in the following table: System 1 System 2 System 3...
3.4.2.3 Blower pack The blower packs – in combination with the steam humidifiers Condair RS – are used for direct room humidification. The blower packs are mounted directly on the humidifier or separately above the humidi- fier to the wall.
Check packing slip to ensure all parts has been delivered. All material shortages are to be reported to your Condair supplier within 48 hours after receipt of the goods. Condair Group AG assumes no responsibility for any material shortages beyond this period.
Storage and Transportation Storing Until installation store the Condair RS in its original packaging in a protected area meeting the following requirements: – Room temperature: 5 ... 40 °C – Room humidity: 10 ... 75 %rh Transportation For optimum protection always transport the unit and components in their original packaging and use appropriate lifting/transporting devices.
DANGER! Danger of electric shock! The Condair RS 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 RS must be connected to the mains only after all mounting and installation work has been completed, all installations have been checked for correct workmanship and the unit is closed and properly locked.

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 39
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.

The indicated connection specifications must be observed. Note: The Condair RS can also be fed with reverse osmosis water from the optional Condair RO-E pure water system (see installation overviews in chapter 5.2).
Page 54
– Draining rates: Note: The draining rates shown in the table below apply to the operation of the Condair RS with un- treated drinking water and the factory settings for the water reduction interval time. When operating with reverse osmosis or deionized water, the water reduction interval time can be reduced according to the table in the operation manual, which reduces the draining rate accordingly.
5.5.3 Inspecting the water installation Check the following topics: – Water supply Has filter valve (accessory "Z261") or shut-off valve and 125 µm water filter respectively been installed in supply line to each unit module? Has acceptable water pressure (without drain water cooling: 1 – 10 bar, with drain water cooling: 2 –...
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.
