    Observe and comply with all local and national codes dealing with electrical installations. Condair does not accept any liability for installation of humidification or dehumidification equipment by unqualified personnel, or the use of equipment and parts that are not authorized by Condair. Personnel Qualifications All installation work must be performed only by licensed personnel authorized by the customer.

  • Page 22: Installation Overview

    The Condair DA Desiccant Dryer is designed for indoor installation and can be installed, with ducts, in the room to be dehumidified or in a separate room. The installation requires a duct to remove wet air from the Condair DA Desiccant Dryer, an air duct for the reactivation air, a duct for the dry air outlet (recommended, especially for distribution), and connection to the mains supply (with disconnect switch).

  • Page 23: Clearance Requirements

    Electrical disconnect switch Installation The Condair DA Desiccant Dryer may be installed in the dehumidified room, or in a separate room. To obtain the best performance, equip diffuser to fan outlets. IMPORTANT! Ensure that the rooms supplying air to the dehumidifier and rooms requiring dry air from the dehumidifier are properly vented to reduce formation of pressure imbalance.

  • Page 24: Installing The Unit In A Separate Room

    Does not require duct if coming from the room housing the unit. Requires a duct if coming from elsewhere. Wet air leaves the unit to another location or outside. Requires duct out of the room housing the unit. 24 | Installation and Planning Condair DA 2593630_A_EN_2003_DA_IOM...

  • Page 26: Connecting The Process Air Duct

    Connecting the Process Air Duct Typical installations of the Condair DA Desiccant Dryer do not require a process air duct to the unit because the unit is installed in the space needing dehumidification. Instead, air into the dehumidifier is taken from the space directly.

    ~0.15-0.25 in (4-6mm) may be drilled at the duct's lowest position. Alternatively, a drain line may installed in the duct. Contact your Condair representative for information on proper draining. Place warning signs at the outlet, or where applicable. The wet air temperature may reach above 176 °F (80 °C).
